We are using the SPC56EL70 and it's Flash driver in our Firmware.

Problem description:
While using the Erase API of the Flash driver we have erased the shadow memory area of the Flash memory.

After having erased this area, when the MCU was given a hard reset (by a Power ON/OFF cycle), it is observed to be unusable.

The debugger does not connect to the MCU, and we are unable to download new Firmware.

Problem severity:
The shadow memory erase has been executed on all 5 of our MCU boards, as a result of which all 5 boards have become defunct.

We need urgent help and support to restore the boards to a working state. Kindly provide guidance to help us overcome this problem.

Thanks a lot in advance.
