ls1043ardb flash programing failed by use codewarrior

[lincheng]

Hi,

   I was test ls1043ardb flash programing use codewarrior, i ref the chapter  "7.1 Configuring flash programmer " from
"ARMv8_Targeting_Manual.pdf" . in cwflash.py, i set BOARD_TYPE = "RDB", FLASH_TYPE = "nor",SOC_NAME = "LS1043A",PROBE_CONNECTION = "". then i launch  aarch64-fsl-gdb.exe ,and then do cmd " source ../../gdb_extensions/flash/cwflash.py ". but somethings is wrong, the log likes below.it says "[Failed to read memory from address 0x1ee00c8 on core SAP#0.GTA: error reading memory]". Do anyone know what is wrong with it ?

Hello lin cheng,

Please try to refer the first section "CodeWarrior Connects to the Bare Board to do Flash Programing" in this document Use CodeWarrior for ARMv8 to Debug U-boot and Linux Kernel and Bring up Bare Boards  to do flash programming.

Have a great day,
TIC
