Our TTN gateway worked for 15 days and now since three days it suddenly stopped working.

Resetting the gateway by holding the button while powering on the gateway will erase the serial flash including all settings and the firmware. Don’t do that unless you know what you’re doing.
Please suggest us how to troubleshoot. For reference please find the image
I had this too. Well at least it is not looping around the reset. Don’t panic it does not mean that you have ‘bricked’ your device. This will burst back into life when you upload the next version of code.
Are you sure? I erased the serial flash quite a few times and that certainly did not erase the bootloader†. Also, from another topic:
Of course, this does not mention pressing the Mode button while booting, but also does not mention the need for a PICkit in case of failure.
If holding down the mode button can indeed erase the bootloader then I feel the instructions should be removed from TTN Gateway - FAQ altogether.
† I even think it did not erase the factory firmware, according to my January 18th and January 25th posts, where I only got updated firmware on February 6th, so would not have had an SD card inserted to re-flash the firmware in January, I think.
The only way the bootloader can be changed is with a programmer like the pickit. It should always be possible to reinstall the firmware using an SD card.
I’m not sure why some gateways are unable to boot after erasing the serial flash. The serial flash does store the OTA firmware updates downloaded from our update server, so my suspicion is that the gateway thinks that all those zeros in the serial flash (after erasure) are the newly downloaded firmware and tries to run it. I’ll forward this to the gateway team. Maybe they can explain what happens.
