We have designed custom board using reference of FRDMLS1012A.On custom board when we try to connect CodeWarrior TAP it gives error ERROR: Memory access failed. I have attached screen shot here.

Flashing Mehod :

1) Select target board in codewarrior (FRDM-LS1012) studio.

2) Click to connect icon to connect with device.It is giving error.

3) When selecting diagnose option it will display following error.

Please let me know if i am missing something.

Check CodeWarrior SDRAM initialization for your board.

Find .pl initialization files for LS1012a board using the following path:

C:\Freescale\CW4NET_v2016.01\CW_ARMv8\Config\boards

Test your board using OCRAMx memory of the LS1012a as code and data memory for your test program.

Have a great day,

Hi Pavel

On Initialization script it stuck in Reset().

if USE_SAFE_RCW:
        # Set rcw_src to hard-coded RCW option
        gdb.execute("monitor rcw source set 0x9E")
        gdb.execute("monitor rcw apply")

When it tries to run gdb.execute("monitor rcw apply") command it gives ccs:Subcore error encountered during multicore operation error. I have attached script which I am using for flashing .

Note : we have modified RAM as listed below.

In FRDM RAM part no:

MT41K256M16TW-107:P

In custom board :

MT41K1G8SN-125:A
