Follow the instruction given in "flash programmer" section of "CodeWarrior Development Studio for QorIQ LS series for ARM v8 ISA"  documents to do flash programming.


Steps Followed:To start the flash programmer, perform the following steps:


Update the with 'PROBE_CONNECTION = "cmsisdap:20000203C19E4E733C62918B" ', 'SOC_NAME = "LS1012A" '.Rest are as it is.


  1. Open a terminal and switch to the following location:
    {CW Install Dir}\CW_ARMv8\ARMv8\gdb\bin 
  2. Start GDB from this location:
    • Windows: Run aarch64-fsl-gdb.exe
    • Linux: Run ./aarch64-fsl-gdb
