I am trying to update  u-boot image in FRDM - LS1012A using CMSIS-DAP debugger with CodeWarrior Development Studio for QorIQ LS series - ARM V8 ISA.

 

So far I have done the followings steps:

1. Loaded the cmsis dap firmware provided in this thread in K20.

2. Followed the steps mentioned in CodeWarrior Development Studio for QorIQ LS series - ARM V8 ISA Targeting Manual, Rev. 11.2.2, 10/2016 for flash programming. 

 

When I execute the cwflash.py script  the following messages are shown.

 

Starting flash programmer services...
Starting local server...

Additional error details:

Closing debugger server...

Can some one point, where am I doing wrong?

 

Thanks
