Problem with Craneboard booting the kernel

Bartek Taczala

Hi,

I've some problems with booting the kernel. I've compiled x-load and u-boot manually, as well as kernel, but it seems kernel either won't run, or it's not properly configured to printk messages to ttyS2 ( I had to manually turn on Device Driver -> Graphics Support ->Console Display Support -> Framebuffer console support )

I don't know if either kernel does not run correctly ( although I know that decompress_kernel from kernel sources is called ), or I have something wrongly configured.

I've also tried prebuild kernel image from TI SDK, but it won't start due to device id being different.

My u-boot env:

AM3517_CRANE # pri
bootcmd=if mmc init; then if run loadbootscript; then run bootscript; else if run loaduimage; then run mmcboot; else run nandboot; fi; fi; else run nandbooti
bootdelay=10
baudrate=115200
bootfile=uImage
loadaddr=0x82000000
console=ttyS2,115200n8
mmcargs=setenv bootargs console=${console} root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait eth=${ethaddr} ip=dhcp
nandargs=setenv bootargs console=${console} root=/dev/mtdblock4 rw rootfstype=jffs2 eth=${ethaddr} ip=dhcp
loadbootscript=fatload mmc 0 ${loadaddr} boot.scr
bootscript=echo Running bootscript from mmc ...; source ${loadaddr}
loaduimage=fatload mmc 0 ${loadaddr} uImage
mmcboot=echo Booting from mmc ...; run mmcargs; bootm ${loadaddr}
nandboot=echo Booting from nand ...; run nandargs; nand read ${loadaddr} 280000 400000; bootm ${loadaddr}

And that's all I can see through minicom.

Hi Bartek,

Hope you have downloaded images and followed the procedure mentioned here: http://processors.wiki.ti.com/index.php/Building_images_for_CraneBoard

Looking the console log, I strongly suspect the kernel image you have built.

Hi,

yes I followed those instructions, but while compiling u-boot I'm running into linking errors:

lib_arm/board.c:299: undefined reference to `register_diagnostics'

armv4t/libgcc.a(_bswapsi2.o):(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr0'

The first error is fixed by commenting the line in which call to register_diagnostics occurs, the second is fixed by patch ( http://lists.denx.de/pipermail/u-boot/2010-May/071363.html )

Is my necessary modifications causes kernel not to boot properly?

Hi Bartek,

You can comment "lib_arm/board.c:299" as this is pointing to register diagnostics routine in the ITBOK and i reckon that is not of no interest here.

However you can download the same here: http://processors.wiki.ti.com/index.php/Building_images_for_CraneBoard#Integrating_and_Building_ITBOK

Apart from downloading the sources you should also be tweaking the Makefile in u-boot to accomodate ITBOK, more details on the same is mentioned here: https://github.com/craneboard/craneboard-itbok/wiki/Integrating-and-building-ITBOK

Hi,

So I've built with ITBOK itegration, but kernel still won't boot ( or perhaps it's running, I can't verify this really, since there's no output from kernel )

Hi,

problem was solved by switching SD/MMC card.
