can not connect to target

[naderkhamess]

Hello,

I was overwriting my existing bootloader by using FLASH APIs. After executing the commands I can not connect with target anymore. Could you please support me here? 

I attached the error. My hardware is S32k146

Hi naderkhamess,

It seems that you wrongly modified the value of address 0x400-0x40F with FLASH APIs. Please try to connect the Core and read MDM_AP status register by refer to: Unbricking S32K146

Best Regards,
Robin

Hi Robin,

I tried now to follow instructions, and its always showing :

" Unlocking device...Timeout while unlocking device."

Flash memory is not ready (Status[1]) and MCU secured (Status[2]).
Sorry, I'm afraid you need a new chip.
