I built an ELF image for QEMU and executed it with this command: qemu-system-arm -kernel build/images/bootstrap_lx_ginger-arm.elf -M realview-pbx-a9 -serial stdio -m 256
Any ideas on what's going wrong or next steps I can take to diagnose the issue? Thanks!
Best regards, Michael LeMay http://m.lemays.org
Hi,
I think, that this problem is related to the way the TLS is handled. Thus init times out waiting for the ueventd to create all necessary devices. Init then starts the servicemanager which does no checks on opening devices.
We have an internal solution but this is not yet ready to be pushed to the public. However it should work with the prebuilt images.
Br, Matthias.

I built an ELF image for QEMU and executed it with this command: qemu-system-arm -kernel build/images/bootstrap_lx_ginger-arm.elf -M realview-pbx-a9 -serial stdio -m 256
Any ideas on what’s going wrong or next steps I can take to diagnose the issue? Thanks!

Thank you for the explanation. Having access to the prebuilt root and system images used in the ARM demo would be helpful. Are they already posted online? I only saw X86 images listed on this page: http://l4android.org/download/download.html Thanks.
Best regards, Michael LeMay http://m.lemays.org

Hi,
I think, that this problem is related to the way the TLS is handled. Thus init times out waiting for the ueventd to create all necessary devices. Init then starts the servicemanager which does no checks on opening devices.
We have an internal solution but this is not yet ready to be pushed to the public. However it should work with the prebuilt images.
Br, Matthias.

I built an ELF image for QEMU and executed it with this command: qemu-system-arm -kernel build/images/bootstrap_lx_ginger-arm.elf -M realview-pbx-a9 -serial stdio -m 256
Any ideas on what’s going wrong or next steps I can take to diagnose the issue? Thanks!

Thank you for the explanation. Having access to the prebuilt root and system images used in the ARM demo would be helpful. Are they already posted online? I only saw X86 images listed on this page: http://l4android.org/download/download.html Thanks.
I now uploaded the images. Make sure to boot L4Android with androidboot.harware=l4android on the cmdline.
Matthias.

Hi,
I think, that this problem is related to the way the TLS is handled. Thus init times out waiting for the ueventd to create all necessary devices. Init then starts the servicemanager which does no checks on opening devices.
We have an internal solution but this is not yet ready to be pushed to the public. However it should work with the prebuilt images.
Br, Matthias.

I built an ELF image for QEMU and executed it with this command: qemu-system-arm -kernel build/images/bootstrap_lx_ginger-arm.elf -M realview-pbx-a9 -serial stdio -m 256
Any ideas on what’s going wrong or next steps I can take to diagnose the issue? Thanks!
