Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root filesystem. Do you have an idea of what might be wrong.
Thank you in advance.
Best regards, Mahdi

Hello,
I tried to run L4Linux + Fiasco on a Freescale i.mx http://i.mx 6 Sabre SD board.
The L4Linux is started but it stops at loading the ramdisk, as shown in the debug messages below.
Does someone has an idea of what might be wrong.
Thank you very much in advance.

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?
Matthias.

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.
Best regards, Mahdi

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root filesystem. Do you have an idea of what might be wrong.
Thank you in advance.

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
I don't have a clear idea of what's going wrong. First I would try to start /bin/sh instead of /bin/init and see if that works.
Matthias.
Thanks in advance.
Best regards, Mahdi

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:
RAMDISK: ext2 filesystem found at block 0 RAMDISK: Loading 3072KiB [1 disk] into ram disk... done. EXT4-fs (ram0): couldn't mount as ext3 due to feature incompatibilities EXT4-fs (ram0): mounting ext2 file system using the ext4 subsystem EXT4-fs (ram0): mounted filesystem without journal. Opts: (null) VFS: Mounted root (ext2 filesystem) readonly on device 1:0. devtmpfs: mounted Freeing unused kernel memory: 116K (02313000 - 02330000) Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.
Best regards, Mahdi

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.
Best regards, Mahdi

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root
filesystem.
Do you have an idea of what might be wrong.
Thank you in advance.
Best regards, Mahdi

Hello l4-hackers,
I found a thread [1] from 2014 with the identical issue that I have. I followed the answer and I applied the solution proposed (which worked in the case of the mentioned thread). But unfortunately did not worked in my case, I still have the same issue as indicated below.
Any help will be very appreciated.
Many thanks in advance.
best regards, Mahdi

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.
Best regards, Mahdi

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.
Best regards, Mahdi

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root
filesystem.
Do you have an idea of what might be wrong.
Thank you in advance.

Hello l4-hackers,
I found a thread [1] from 2014 with the identical issue that I have. I followed the answer and I applied the solution proposed (which worked in the case of the mentioned thread). But unfortunately did not worked in my case, I still have the same issue as indicated below.
Any help will be very appreciated.
Many thanks in advance.
There's also the Linux print-fatal-signals=1 cmdline option which should print some more info and could give more hints.

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.
Best regards, Mahdi

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.
Best regards, Mahdi

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root
filesystem.
Do you have an idea of what might be wrong.
Thank you in advance.

Hello Adam,
I added the "print-fatal-signals=1" option to l4linux command line as you suggested.
I did a make clean and I re-started from a fresh default L4Linux configuration. On which I set the "System Type -> Build type" option equal to ARMv7 for l4linux in order to be able to enabled all the floating point related options:
CONFIG_VFP=y CONFIG_VFPv3=y CONFIG_NEON=y CONFIG_ARM_THUMB=y
Then I did a re-compiled the l4linux kernel. I get an "alignment error" when l4linux tried to load the RAMDISK as shown below.
Do you have any idea of what might be wrong or any hints to track down the issue.
Thank you very much for your help.
Best regards, Mahdi

Hello l4-hackers,
I found a thread [1] from 2014 with the identical issue that I have. I followed the answer and I applied the solution proposed (which worked in the case of the mentioned thread). But unfortunately did not worked in my case, I still have the same issue as indicated below.
Any help will be very appreciated.
Many thanks in advance.

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.
Best regards, Mahdi

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.
Best regards, Mahdi

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root

Do you have an idea of what might be wrong.

I added the "print-fatal-signals=1" option to l4linux command line as you suggested.
I did a make clean and I re-started from a fresh default L4Linux configuration. On which I set the "System Type -> Build type" option equal to ARMv7 for l4linux in order to be able to enabled all the floating point related options:
CONFIG_VFP=y CONFIG_VFPv3=y CONFIG_NEON=y CONFIG_ARM_THUMB=y
Ok good.
Then I did a re-compiled the l4linux kernel. I get an "alignment error" when l4linux tried to load the RAMDISK as shown below.
Do you have any idea of what might be wrong or any hints to track down the issue.
Thank you very much for your help.

The Linux is crashing before the virtual serial inside Linux is set up, that's why we do not see anything. What typically helps is early-printk. Thus, make sure to enable CONFIG_EARLY_PRINTK in the L4Linux config and to put earlyprintk=1 on the Linux command line. That should hopefully show more and also the reason for the error.
Adam
Hello Adam,
I added the earlyprintk=1 option to linux boot command and I enabled the CONFIG_EARLY_PRINTK.
The debug messages below show more information compared to logs from the previous tests.
Could you please tell me what do you think might be the cause of the error.
Many thanks in advance.
Best regards, Mahdi

Hello Adam,
I added the "print-fatal-signals=1" option to l4linux command line as you suggested.
I did a make clean and I re-started from a fresh default L4Linux configuration. On which I set the "System Type -> Build type" option equal to ARMv7 for l4linux in order to be able to enabled all the floating point related options:
CONFIG_VFP=y CONFIG_VFPv3=y CONFIG_NEON=y CONFIG_ARM_THUMB=y
Then I did a re-compiled the l4linux kernel. I get an "alignment error" when l4linux tried to load the RAMDISK as shown below.
Do you have any idea of what might be wrong or any hints to track down the issue.
Thank you very much for your help.
Best regards, Mahdi

Hello l4-hackers,
I found a thread [1] from 2014 with the identical issue that I have. I followed the answer and I applied the solution proposed (which worked in the case of the mentioned thread). But unfortunately did not worked in my case, I still have the same issue as indicated below.
Any help will be very appreciated.
Many thanks in advance.

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.

Hi,
its just an educated guess, but I suspect that /bin/init tries to access some devices in /dev. Have you enabled devtmpfs and the devtmps automount option in L4Linux?

Hello,
Thank you very much Mattias for you help.
Now L4Linux goes further but it stops after mounting the root
filesystem.
Do you have an idea of what might be wrong.
Thank you in advance.
Best regards, Mahdi

The debug messages below show more information compared to logs from the previous tests.
Could you please tell me what do you think might be the cause of the error.

Ui, this location is known to me. If you change "char empty_str[]" to "char *empty_str" in pcpu_dump_alloc_info it will work. But this is just a side note. Better disable the alignment checking in Fiasco's config, as this is more of a debugging helper.

Hello Adam,
After disabling the alignment checking in Fiasco, L4Linux goes further now. Thank you!
However, there is still a problem after the mount of the root filesystem as shown below.
Do you have an idea of what might be wrong.
Many thanks in advance.
Best regards, Mahdi

Hello Adam,
I added the earlyprintk=1 option to linux boot command and I enabled the CONFIG_EARLY_PRINTK.
The debug messages below show more information compared to logs from the previous tests.
Could you please tell me what do you think might be the cause of the error.
Many thanks in advance.
Best regards, Mahdi

Hello Adam,
I added the "print-fatal-signals=1" option to l4linux command line as you suggested.
I did a make clean and I re-started from a fresh default L4Linux configuration. On which I set the "System Type -> Build type" option equal to ARMv7 for l4linux in order to be able to enabled all the floating point related options:
CONFIG_VFP=y CONFIG_VFPv3=y CONFIG_NEON=y CONFIG_ARM_THUMB=y
Then I did a re-compiled the l4linux kernel. I get an "alignment error" when l4linux tried to load the RAMDISK as shown below.
Do you have any idea of what might be wrong or any hints to track down the issue.
Thank you very much for your help.
Best regards, Mahdi

Hello l4-hackers,
I found a thread [1] from 2014 with the identical issue that I have. I followed the answer and I applied the solution proposed (which worked in the case of the mentioned thread). But unfortunately did not worked in my case, I still have the same issue as indicated below.
Any help will be very appreciated.
Many thanks in advance.

Hello,
Thank you Matthias for your answer.
I didn't put "/bin/init" as a parameter in the "l4lx.cfg" file. I used the default version of the file and the "init" parameter was not set.
I added to the config file "l4lx.cfg" the parameter "init=/bin/sh" but it gives a similar error. As shown in the debug messages below:

However, I tried the same l4linux with the same ramdisk on a Qemu versatile express ARM Cortex A9, it worked fine and I get a shell prompt.
Does someone has an idea of the problem or any hints about how to track down the issue.
Many thanks in advance.

Hello Matthias,
Thank you for your help.
I enabled the CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT options as you suggested, as shown below in a piece from a .config file:
Then I get another error which I think is different from the mount of the filesystem. But it is still difficult to say what might be wrong.
Could you please tell me what should I check to track down the source of the issue.
Thanks in advance.

Hi,

However, there is still a problem after the mount of the root filesystem as shown below.
Do you have an idea of what might be wrong.
This tells us that the 'sh' is doing something wrong or triggers something that makes it crash due to a signal. Which ramdisk is this? One of mine? On the current one the pc location has just a register move, so likely not the one. The PC value is always the same of consecutive tries? Could you send me the /bin/sh of the ramdisk you're using (private mail).
