Kernel Hang

Added by Andrew Holt about 13 years ago

Hi,

I have a MityDSPL138 in the industrial IO board. I have built a new kernel, (2.6.34-rc1) It hangs when I try to boot.

I can boot the board from another copy of the kernel, both from flash & by tftp

Here are the u-boot settings:

U-Boot > printe

And that's it. It does nothing else.

Hi Andrew,

Can you please identify where you got the kernel (is it from support.criticallink.com, arago, the TI PSP, or mainline?) and what commit point you are working with? You might also want to include the .config file so that we might be able to reproduce the hang.

I looked for g2e70fb6 in our repository commit log and nothing popped up... my guess is you have local changes on top of a public kernel point?

Thanks.

Mike -

Andrew provided this information to me prior to posting on the forum:

I built a kernel, following the instructions at http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Installing_Open_Embedded

With the following commands:

 
git clone git://support.criticallink.com/home/git/linux-davinci.git linux-davinci
cd linux-davinci/
git checkout -b devel origin/devel
. /usr/local/angstrom/arm/environment-setup
unset CPATH
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- mityomapl138_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage

Hi,

I built the kernel as per the instructions here: http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Kernel

I have made no local changes, I can't get the vanilla one to work :)

.config attached

config (42.9 KB) config

RE: Kernel Hang - Added by Michael Williamson about 13 years ago

Ok,

Sorry guys. I need to update the instructions on that page. The devel branch is no longer maintained, and you should always reference new work off of the master. The proper instructions, for the Industrial I/O board, should be something like:

git clone git://support.criticallink.com/home/git/linux-davinci.git linux-davinci
cd linux-davinci/
git checkout -b my_work origin/master  # the devel branch is OBE, and should be removed
. /usr/local/angstrom/arm/environment-setup
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- industrialio_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage

Note the change to the _defconfig file, BTW. (industrialio_defconfig, not mityomapl138_defconfig).

RE: Kernel Hang - Added by Andrew Holt about 13 years ago

Hi,

That did it !

I now have a working kernel, that I have built. Onward now to getting the DSP stuff to work :)

Many thanks,
Andrew
