Recompiling kernel with TI8148 PSP

Mike Thornhill

I have been following along in the TI81XX PSP User Guide to rebuild the kernel for my 8148 EVM.

http://processors.wiki.ti.com/index.php/TI81XX_PSP_User_Guide

The path for my CodeSourcery toolchain is here and I have added this to my path:

~/CodeSourcery/Sourcery_G++_Lite/arm-none-linux-gnueabi/bin

Would someone point me in the right direction regarding the errors that I am receiving when using the following two commands:

make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm ti8148_evm_defconfig

make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm uImage

l/linux-04.04.00.02$ pwd

~ti-ezsdk_dm814x-evm_5_05_02_00/board_support/TI81XX-LINUX-PSP-04.04.00.02/src/kernel/linux-04.04.00.02

Thank you for your comments.

Please give the complete path of arm tool chain.

The path is:

/home/mike/CodeSourcery/Sourcery_G++_Lite/arm-none-linux-gnueabi/bin

I meant give correct path in the build command as below.

CROSS_COMPILE = /home/mike/CodeSourcery/Sourcery_G++_Lite/arm-none-linux-gnueabi/bin/arm-arago-linux-gnueabi-

I don't see a file callled arm-arago-linux-gnueabi- anywhere.

/home/mike/CodeSourcery/Sourcery_G++_Lite/arm-none-linux-gnueabi/bin/arm-arago-linux-gnueabi-

but what I do see is:

/home/mike/CodeSourcery/Sourcery_G++_Lite/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-

Does my configuration seem incorrect?

Thanks.

arm_arago_* is arago tool chain. arm_none_* is CodeSourcery tool chain. You can use existing CodeSourcery tool chain. Some relevant information at below links.

1.) The issue that I was having was the error being generated about "cc1". This was not in my path and once it was I was able to compile the uImage.

2.) I have been following this guide to rebuild the kernel with the updated PSP.

http://processors.wiki.ti.com/index.php/TI81XX_PSP_User_Guide#Boot_from_SD_Card

Now when I boot the kernel I receive:

<...>

syslink: disagrees about version of symbol module_layout

FATAL: Error inserting syslink (/lib/modules/2.6.37/kernel/drivers/dsp/syslink.ko): Invalid module format

I don’t see a step here in the guide to update the kernel objects such as syslink.ko and cmemk.ko.

What am I missing here?

You need to rebuilt KOs as well. I will try to get the input from right person who has info about ezsdk. Meantime check "makefile help". It would list details about how to built different module, components etc.

We copied over the Linux sources and u-boot directories to the previous EZSDK directory, also modified Rules.make.

Mike,

Either do a "make all" or "make syslink" followed by "make syslink_install" to build syslink manually.
