I have STM8L151G4 with ROP set and I'm using UART interface. In my software there is an function which jumps to bootloader at 0x602d and it works fine. I can use commands like 'get' or 'go', but writing doesn't work. Here is my comunication log with bootloader after jump with ROP set:
Trying to disable ROP:
T: 0x7f
R: 0x79
T: 0x31ce
R: 0x79
T: 0x0000480048
R: 0x79
T: 0x00aaaa
R: timeout
Trying to write to flash:
T: 0x7f
R: 0x79
T: 0x31ce
R: 0x79
T: 0x0000840084
R: 0x79
T: 0x000000
R: timeout
Is there any way to upgrade firmware or disable ROP through bootloader? Maybe I'm doing something wrong? After these commands nothing happens and bootloader doesn't respond.
