device is secure. erase to unsecure?

[d_shivamkumar]

i was performing memory erase task and then suddenly my s32k144 board is also not working. its showing the prompt of 'device is secure. erase to unsecure?', even if i choose yes or no from the options, still the same prompt is showing. how ot resolve this issue so that i can use my s32k144 EVB again? currently i am unable to flash anything (OpenSDA and PEmicro debugging tried).

Hello,

Did you have the Flash partitioned for CSEc operation (number of Flash Keys not 0) prior to trying to erase it?

Best regards,

no

i just started erasing pflash from 1st sector (1st memory location address which is 0000 0000) upto 128th(last) sector. before performing i was using some example code to erase 64th sector wich the memory location address is (0004 0000) but then it was working just fine and just when i've tried erasing 1st sector, this issue came.

Did you try the emergency recovery option?
