AM335x U-Boot CCS6 debugging

Arndt Kritzner

Hi,

with u-boot 2013.07 MLO debugging works well as described in http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5. there is no s_init-function in board.c and after jumping to 0x402F0400 the execution seems to start in arch/arm/lib/vectors.S in _start(). But neither in vectors.S nor in board.c it is possible to set a valid breakpoint.

What am I doing wrong?

Kind Regards

Hi,

The wiki link you give is old. There are a lot of changes in code since then. I will ask the software team to comment on this.

Hi Arndt,

the function s_init() was moved at some point from "<u-boot-dir>/board/ti/am335x/board.c" to "<u-boot-dir>/arch/arm/cpu/armv7/am33xx/board.c".
There is a wiki page which has the correct path to "board.c", but otherwise it do not look much different from the one you are using:
processors.wiki.ti.com/.../Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5_sdk7

Yordan

Hi Yordan and Biser,

this problem persists. It is possible to connect and activate the target and to load memory and symbols as described in the above given tutorial. Source code can be loaded and breakpoints can be created. With the uboot-2015.07+gitAUTOINC+5922e09363 (SPL/MLO) no breakpoints can be activated. Every attempt to activate a breakpoint is answered with an "No code is associated with <file>, line <line> in any loaded symbols". In "Disassembly" symbol names do appear. Any Ideas to fix this situation?

Thanks and Regards
Arndt

Hi Arndt,

which version of CSS are you using? It seems that there was some bugs in the CSS which caused similar behaviour and it must be fixed in the latest version. You can check this thread:

Hi Yordan, this is CCS version 6.1.2.00015. Ok, I will try 6.1.3 if this solves my issues.
