Question:
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”.
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”.
