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
