Hello,
how do you test L4 on an ARM platform? Do you have specific hardware for that purpose? You mentioned that you use ARM Integrator boards. As there are several integrator boards available: which one exactly do you use? Do you use other boards as well? I'm asking because I plan to buy an ARM board which is supported out of the box without the need to modify drivers.
Do you additionally use software simulators to test L4? If so, which one do you use? I tried Skyeye to simulate an ARM integrator board as well as a SA1100-board but didn't get any output over the serial line. Qemu doesn't work either and terminates with the following error: "qemu: uncaught target signal 11 (Segmentation fault) - exiting".
Kind regards, Daniel

I'm using Qemu with the integrator targets it offers. I could never test on a real Integrator board.

Qemu works just fine for me and I cannot remember any crash of Qemu itself when using it. I've never used skyeye (as Qemu always worked ok for me).

Qemu-arm seems to crash no matter which ARM board I choose. It crashes always at the same location (the first instruction of the __main function - see below) although the base address differs from board to board:

When Qemu itself crashes something is strange with your Qemu. I wouldn't look at the guest code at all then. Which version of Qemu are you using?

Hello,
after I was able to get Fiasco to work with serial output under Qemu (Skyeye still doesn't output anything), I'm trying to get L4Linux to work with the ARM integrator. Attached you will find a boot log as well as my kernel configuration. I tried to remove as much as possible device drivers. Do I have to enable/disable some kernel options? I would greatly appreciate any help. Btw. for some reason I had to link <l4linux>/lib/lib.a to <l4linux>/arch/l4/lib/arch-arm/lib.a manually.

You still have to enable CONFIG_BLK_DEV_RAM, at least. And you don't seem to have included any filesystem (ext2, cramfs) that is probably needed for the ramdisk to work.
