Yes. i think it is erasing configurations. To cross check before programming specific P1 i saved configuration in one file using stlink(at location 0x08004000) and when installing bootloader at that time i also programmed this configuration file so in that case after connecting with wifi it is working. No red blink.
But in one of my device, i never claimed on particle and in that P1 OS crashed so tried same step with “particle keys doctor” but for specific that module it give error message like “Make sure your device in DFU mode or your pc is online” Same case like this Post
So i can solve issue for device which is already claimed on particle but any idea about what if device is not claimed on particle?
