Hello,

'???'- means that memory is not accessible at this time or it is full of ECC errors, which is very rare case.

• The MCU is running and the debugger can’t access the flash at that moment.
• The address you typed is incorrect or not aligned.
• The flash controller (C55FMC for S32K3) is busy erasing/writing → flash is temporarily unreadable.
• The debugger is not fully connected or the MCU is not halted.

0x00600000 - 0x006FFFFF is valid range for S32K314 of Program flash (Block 2).

So I assume that MCU is running (not in a stop /suspend debug mode) or some operation is running on this flash block.

Best regards,

Peter
