Good day,
We have a custom board with S32K146 MCU and we are using SEGGER J-Flash to flash it. But now we have problems with write protection.
First when we are trying to connect we are getting this message:
![0_wr_prot_message.png 0_wr_prot_message.png](/t5/image/serverpage/image-id/75731i72A07592C54591C0/image-size/large?v=v2&px=999)
If answer YES, J-Flash is asking the same question encore 3 times, and after that the connection will not be established with the message
![1_no_erase_error.png 1_no_erase_error.png](/t5/image/serverpage/image-id/75732i54C551B8473C3541/image-size/large?v=v2&px=999)
If answer NO, the connection establishes but if we will try to erase chip, we are getting error and then target disconnects
![2_yes_error.png 2_yes_error.png](/t5/image/serverpage/image-id/75733i0B0F45515C2F935A/image-size/large?v=v2&px=999)
We will appreciate any help to unlock write protection.
Thanks,
