The fix depends on why the error occurred. Do not simply re-flash blindly—you risk masking an underlying hardware fault. flash check error address 0h

: Flash memory must be completely empty (all bits set to FF ) before new data can be written. He realized his tools weren't plugged in

: Flashing a chip while it is still on a circuit board can cause the programmer to try and power the entire board, leading to a voltage drop that causes write errors. flash check error address 0h

If the error persists after multiple erase/program cycles:

Most modern microcontrollers have a that is immune to flash corruption.
