Hey.
I was playing with a code once suddenly I could not send anything to MCU. Keil returns me multiple lines like this with different addresses:
"Contents mismatch at: 08040FE1H (Flash=FFH Required=00H) !"
The programming algorithm is fine.
In STLink Utility, I have noticed that write protection has been enabled (sectors 0-15 disabled, 16-31 enabled, 32-47 disabled, 48 - 63 enabled, and so on). I have tried to disable write protection entirely by STLink utility and CLI...no luck. The weird thing is that the address pointed by Keil is not in a protected area. I see that some sectors can be modified and some not (but they are not even marked as a protected! - like sector 32, which is not protected, but the content could not be changed during programming!).
When I tried to modificate write protection in CLI, only MSB of the value changes:
0x0000FFFF-> 0xFFFFFFFF -> 0x0000FFFF ... the LSB part stays the same.
It is a new MCU - is it possible it is a manufacturer issue?
Is it better to buy a new MCU or is there some workaround for this issue?
Cheers,
Rob
