How to use VVDI PROG to read EEPROM and FLASH of a STM8AF6266 MCU with active ROP protection.
EEPROM, FLASH, OPTION, all data show “00”.
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”.
