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...
