Re: [ts-7000] [ts-7500]: Booting kernel 2.6.36

[Frederico Gonçalves <>]

Yes, I've got the kernel from the ftp server (ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7500-linux/sources/linux-2.6.36-ts7552.tar.bz2).

I'm using the ts7500_config that comes with it. One funny thing, if I use the following commands I can get it working and booting without a problem:

- make ts7500_defconfig

- make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- EXTRA_CFLAGS='-march=armv4 -mno-thumb-interwork -mno-thumb -mfloat-abi=soft'

I'm also able to boot into debian, issue a depmod and start using kernel 2.6.36.

However, I need more modules than those that are compiled. So I enable them through menuconfig and remove somethings I don't need (such as nfs support). After this, I use the same make command to compile the kernel, which succeeds without a problem. But this time, the board keeps reseting after uncompressing it.

I just don't know what can be the cause for this. By using the same procedure in kernel 2.6.35.11 long term revision, I obtain exactly the same behavior.

Thanks for the help,

I'm currently using ts-7500 for my projects. Lately I've been trying to boot kernel 2.6.36. I'm able to compile it without a problem. However, when trying to boot it, the ts-7500 just keeps rebooting after uncompressing the kernel. Moreover, I think it is uncompressing the kernel image too fast, as if something is wrong with it.

Has someone experienced similar behavior?

More info:

- I'm using arm-linux-gnueabi-gcc available in the ubuntu distro, to compile the kernel.

- I compile it with '-march=armv4 -mno-thumb-interwork -mno-thumb -mfloat-abi=soft' to avoid thumb instructions.

- I've also tried an uncompressed kernel image, but got the same results.

Where you get 2.6.36 sources (I believe from TS ftp)?
What .config do you use ?
