Question:

Can I use VVDI PROG to read EEPROM and FLASH of a STM8AF6266 MCU with active ROP protection.

EEPROM, FLASH, OPTION, all data show “00”.

Answer:

As the prompt, if the data we read is the same or we cannot write data correctly, it means the corresponding data area is read-protected.

ROP: 1 Bytes (The first data of OPTION, it determined whether the chip was protected)

If so, we can’t read the encrypted MCU, and we can only erase it by “Chip Erase”.
