beaglebone: uboot debug in ccs5 through jtag ( XDS100v2 USB Emulato).

[aniket jesu]

Hi all,
I have a beaglebone and I would like to debug u-boot on it, in ccs5. as I know BB has in-built jtag,
I can connect the board through Texas Instruments XDS100v2 USB Emulator in ccs5 for debug purpose!!
Well, I followed this link to set the target configuration>>>


http://processors.wiki.ti.com/index.php/AM335X_StarterWare_Environment_Setup#Debugging_on_BeagleBone_board_using_CCSv5

as in the link I set the configuration then I did "launch the selected configuration", then in debug window,
right click on cortexA8 to say "connect target", I got this>>

so, I guess this is working!! but when I followed this video for reference the to debug uboot>>

http://software-dl.ti.com/sdo/sdo_apps_public_sw/CCSv5/Demos/u-boot_debug_autonomous/u-boot_debug_autonomous.html


as I do, complete configuration for target configuration and say debug I get this error>>>

---------------------------------------------------------------------------------------

Error connecting to the target:
(Error -1266 @ 0x0)
Device is held in reset. Take the device out of reset, and retry the operation.


---------------------------------------------------------------------------------------


am a newbie, need some help!!
 and I'll be glad if anyone suggests me any link or reference which will explain me
complete debug process for begalebone in ccs5.


thanks,

 I would take a look at http://processors.wiki.ti.com/index.php/U-boot_Debug_in_CCSv5 and the link it has to http://processors.wiki.ti.com/index.php/OMAP_and_Sitara_CCS_support for an AM335x GEL file.  It's been a long while since I used this all together, but I updated the first link there with instructions for handling relocation in U-Boot, on my Beaglebone White, and nothing too important should have changed since then for debugging BBB.

thanks for the reply tom

but still stuck in the same error on the other hand I tried to use gdb with open ocd, even stuck thr with some errors!!
have u worked with open ocd and gdb, need some help thr also..

thanks,
