Re: NanoVNA bricked


Adrian Waiblinger, if it shows that there is bad state in firmware, then it seems that memory is corrupted, so the only way to flash it is to use ST-LINK

Just use instruction above. If something will going wrong during flashing with ST-LINK, then use menu Target => Erase chip. It will clean all memory, so you will be able to flash it like new one with menu Target => Program and verify.
