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 script  the following messages are shown.


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

Connecting to target...

Additional error details:

Can some one point, where am I doing wrong?
