Question about JDB in Fiasco
by yang.wei9＠zte.com.cn 30 Aug '15

30 Aug '15

Hi, Adam I have some questions about JDB in Fiasco. 1). Is there any latest manual about JDB? I can only find <Fiasco Kernel Debugger Manual>( http://os.inf.tu-dresden.de/fiasco/doc/jdb.pdf) which is written in 2008. This manual does not conform to the current fiasco version(l4re-snapshot-2014092821)。 2). Does JDB support bt(dump backtrace)? There are some descriptions about "bt" command in <Fiasco Kernel Debugger Manual>. But I can not find it in current version. Does older version fiasco support it? 3). How can I get the older version fiasco code？ Best Regards， Albin -------------------------------------------------------- ZTE Information Security Notice: The information contained in this mail (and any attachment transmitted herewith) is privileged and confidential and is intended for the exclusive use of the addressee(s).

Hello Adam, Thanks for your reply and I'm sorry for the ambiguity of my description. In fact, I have followed that thread and have solved many problems until the last step. ( http://os.inf.tu-dresden.de/pipermail/l4-hackers/2015/007551.html). You guessed that it was the problem of the ramdisk, which I downloaded at http://os.inf.tu-dresden.de/download/ramdisk-arm.rd . After that, you and Mahdi no longer posted messages in this mailing list at this subject. So, I want to know how you address this problem. The output of the execution now appears like this: >* 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.

using math lua module
by AVK 16 Aug '15

16 Aug '15

Quick question, How can i use the math module in lua ? I see that it is there in the contrib folder of lua pkg so it should be built hopefully. Whenever i require("math") in lua, i get an error like Ned: ERROR: rom/json.lua:32: module 'math' not found: no field package.preload['math'] no file 'rom/math.lua' no file './math.so' no file '/usr/local/lib/lua/5.1/math.so' no file '/usr/local/lib/lua/5.1/loadall.so' -- --- Avinash Kundaliya avinash(a)avinash.com.np http://avinash.com.np

Hi l4-hackers, Greetings! I encountered exactly the same problem as Mahdi's. His original thread can be found at http://os.inf.tu-dresden.de/pipermail/l4-hackers/2015/007491.html. AS Mahdi and Adam communicated using private email later, I don't know if the problem has been solved. If it has been solved, can anybody give me some hint on it? Many thanks! Regards, Le Guan

Hi thanks for your answersI want to implement Fiasco.OC on a board and test some RTOS beside other non realtime OS .. at first I want to be sure that if I need a driver for our special tests and the Fiasco.OC does not support that, Could I choose it from linux drivers and port it to Fiasco.OC microkernel?does someone do this work?thanks for your considering my question.regards, shabnam On Saturday, August 8, 2015 10:39 AM, Shabnam Engineer <shabnam.engineer72(a)yahoo.com> wrote: Hi thanks for your answerI want to implement Fiasco.OC on a board and test some RTOS beside other non realtime OS .. at first I want to be sure that if I need a driver for our special tests and the Fiasco.OC does not support that, Could I choose it from linux drivers and port it to Fiasco.OC microkernel?does someone do this work?thanks for your considering my question.regards, shabnam On Thursday, July 30, 2015 5:53 PM, Jorge Alberto Garcia <jorge.garcia.gonzalez(a)gmail.com> wrote: Hi!This is very interesting!, is there any resource about what needs to be done for a user space component handling hw ?Thanks!

In a microkernel system device drivers are implemented as isolated user space components.

L4Linux interface to convert physical address to machine address
by Olujide Adeola 06 Aug '15

06 Aug '15

Hi guys, Apologies if this question has already been answered elsewhere on this mailing list. We are porting our driver to L4Linux but having issues with the page_to_phys() Linux function, what's the L4Linux API to map a VM physical address to a machine address which can be programmed into the DMA registers of a peripheral device on the system bus. Note on terminology, (virtual address <-> physical address <-> machine address). Regards,Olujide

issues in creating an elf binary
by AVK 31 Jul '15

31 Jul '15

Hello, I am trying to create an elf binary for the hello package (to start with) and when i run the `make elfimage` command, it fails with the following error make[3]: *** No rule to make target `mod.make.inc', needed by `bootstrap.ld'. Stop. While i am trying to look into the issue, maybe there is a quick fix for this, or someone has come across this issue already. Or maybe there is a better/easier way to create an elfimage. Regards, Avinash Kundaliya avinash(a)avinash.com.np http://avinash.com.np
