LS1012A-FRDM Codewarrior Flash Error

[인섭심]

I want to download JTAG from LS1012A-FRDM.
I used CodeWarrior's CMSIS-TAP to do the following for Flash Write.

1. put the attached cwflash.py in the folder Freescale \ CW4NET_v2018.01 \ CW_ARMv8 \ ARMv8 \ gdb_extensions \ flash
2. PROBE_CONNECTION = "cmsisdap: COM9"
3. Open CW4NET_v2018.01 \ CW_ARMv8 \ ARMv8 \ gdb \ bin \ aarch64-fsl-gdb.exe
4. type "source C: \ Freescale \ CW4NET_v2018.01 \ CW_ARMv8 \ ARMv8 \ gdb_extensions \ flash \ cwflash.py"

.

.

The following error occurs.

Target reset failed.

Can you tell me the cause of the error?

I attached cwflash.py to the body.

1) Is the board capable to boot?

if not:

2) Is valid RCW present in flash?

[인섭심]

There are two boards.

The mode is the same on two boards.

One will boot normally. (No resistance to R50.)
One does not boot after writing RCW. (Resistance to R50, is this a hard coded RCW?)

> Resistance to R50, is this a hard coded RCW?

Yes, this is hard-coded RCW option.

The board can't boot with hard-coded RCW - refer to the QorIQ LS1012A Reference Manual, 4.4.5.2 Hard-coded RCW options.

The hard-coded option normally should be used to program a valid RCW into the flash.

I made a mistake.
It works well after connecting to JTAG for CMSISDAP.
Thank you for your help.

Please provide the modified "cwflash.py" for inspection.
