RE: Program option bytes on STM32G4xx - embitz - 26-11-2022 Yes, you got the idea. Well, you can just read the content back so if the verify failed, it was because it really failed. I think it goes wrong with the buffer writing, the part that you commented out. I think it's easier to write the whole buffer at once into that sector so that also the inverted part of the options are set. Do you have a small test project for me? I will try to make it working for you. RE: Program option bytes on STM32G4xx - matsb - 28-11-2022 Attached is a test program containing both option bytes blocks. When using STM32CubeProgrammer, I can see from its Log that it reconnects twice to the target, every time after an option bytes block has been written: Quote:WriteOB function terminated with connection error due to OB_launch "I think it's easier to write the whole buffer at once into that sector so that also the inverted part of the options are set." Is that possible? I didn't find any description of that in the reference manual. |
