Hi guys,

I happened to find out that beaglebone was listed in the menuconfig. After that I immediately bought a Beaglebone black (Yeah I know beaglebone is different from bb black, but it might succeed. LOL.) and tried to build a image for my bb black . But I found code errors during compilation.

I use arm-none-eabi tool chains and the gcc version is 4.8.

Errors occurred in

sel4test/libs/libplatsupport/src/clock.c which includes platsupport/plat/clock.h but it doesn't exist

sel4test/libs/libplatsupport/src/plat/am335x/dm.c has several coding mistakes, like:

in function dm_stop_timer() the 'timer' is undeclared in function dm_periodic() dm is undeclared in function dm_get_timer() timer->properties.upcounter = false; but 'false' is undeclared timer->properties.bitwidth = 32; should probably be timer->properties.bit_width = 32;

and timer->start = dm_timer_start; timer->stop = dm_timer_stop; should probably be: timer->start = dm_start_timer; timer->stop = dm_stop_timer;

also I got a redundant redeclaration of 'ki_end' in sel4test/kernel/src/plat/am335x/machine/hardware.c

which the compiler thought the previous declaration of ki_end was in : sel4test/kernel/src/arch/arm/kernel/boot.c

So I am just wandering if beaglebone support is still under development? If any of you run sel4 successfully on beaglebone black, please give me some instructions. Currently I removed building platform independent libraries from menuconfig and the compilation went well. But I don't think it's a good idea.

And I also find the cross tool chains which is recommend for Debian Wheezy on the http://sel4.systems/Download/DebianToolChain.pml seems to be not working well for compiling beagle configs. I got cc1 options error during compiling which is due to that some of the options are supported by gcc 4.5 or later while the recommended one is based on gcc 4.4.

Best regards,

Kun Cheng
