Hello,We have a device that runs an stm32g0. I have a bootloader at the beginning of the flash and then 2 pages for config and the rest of the flash for the firmware. The bootloader basically checks if the two config pages are OK and then starts the ...

The 50'000 writes was just a test, normally, the config gets written only a couple of times during the lifetime of the device. We've analyzed some other devices that were on the same "system" and they all had write times < 50.

I always erase the page before i write it. Of course it is possible that the device loses power or resets (BOR) after the erase and before the write. So I'll have to check the page if it is just erased and not written before trying to read it? How?

Yesterday I've flashed the normal bootloader and a special firmware that write the config pages multiple times (as described above). I've written the config pages about 50'000 times (with a reset after every 100 writes, the bootloader always started...
