TWR-LS1021A -PB Booting Problem from both bank 0 & 1

[ramesharise]

Because of wrong flashing BANK 1 got corrupted (LED5 is continually in green). When trying to troubleshoot from BANK 0 , by loading PBL.bin because of some issues not booting from BANK 0 also. Currently not detecting on CodeWarrior debugger & Tera Term as well. Please help me in bringing up the board.

Hi Adrian,

Thanks you very much. 

Using Codewarrior TAP I am able to bring up the board by overriding the RCW. Thanks for your help.

I hope below link will helpful in overriding RCW.

Thanks you very much Adrian,

I found two options: 1. RCW/U-Boot recovery  2. Complete Board recovery

Thank you very much. Currently I am using CMSIS-DAP connection for debugging/programming. I am following given steps to recover RCW/U-Boot recovery. I think it needs, external CodeWarrior TAP probe connection for overriding RCW, wich I don't have, so I stopped here. Currently I am getting below the errror, while I an trying to use with CMSIS-DAP:

"Error launching 

CCSProtocolPlugin : Could not connect to the probe (or other debug link)"

So I will go a head with 2nd option: Complete board recovery, I hope it doesn't required external CodeWarrior TAP probe connection, but have to resolve in Linux environment. 

Is any options to recover the board using CodeWarrior TAP (over USB / Ethernet) kindly let me know. 

Thanks.

RCW override is supported only using CodeWarrior tap. CMSIS-DAP doesn't support this due a limitation in cmsisdap library provided by ARM.

Using CodeWarrior tap you will be able to follow the steps from targeting manual, regarding RCW override.

Please take a look on CW_ARMv7_Targeting_Manual (\ARMv7\Help\PDF\), Chapter 8 JTAG Configuration Files, to see how RCW override can be used for board recovery.  

Useful for your situation are chapter 8.2 and 8.4. Also Chapter 4 Board recovery from https://community.nxp.com/docs/DOC-332382 , provides the necessary steps for board recovery.
