YET? any clues on what it could be used for? ---

> [@GrahameH](#): > > YET? any clues on what it could be used for? I don’t think the TTN firmware will be using it. But if people flash their own software, one could use it just like one could use the other sockets. (But just guessing.) ---

Whoohoo, I managed to compile firmware from the github code, a few caveats to discover and tricks to apply. Did anyone know what the filename must be for the update file on the sd card and/or how to trigger an update? I tried it with update.zip, firmware.zip firmware.hex, things-gateway-cyberjunky-1.0-test.zip and simply booting, but no trace, maybe a button press is needed? ---

The files should be in a subfolder called `/update/firmware.hex` (about 2.8 MB) and `/update/checksums` (a few bytes). (See also [No LED, no UART output on TTN Gateway after reset](https://www.thethingsnetwork.org/forum/t/no-led-no-uart-output-on-ttn-gateway-after-reset/12054/12) for a note about possible formatting issues.) ---

It worked lol! I even got packets transmitted, I never had that yet, but the reboot loop is still there 😑 at least I can add debug messages and tweak stuff.

It seems the reboot loop (for me) [is triggered by a watchdog timer](https://www.thethingsnetwork.org/forum/t/ttn-gateway-faq/11173/16). So we might be able to find the cause, or increase the timer… (Or, in my case, it might actually be a proper WDT reset as it occurs after several `LORA: Configuration failed, retry`.)

Yeah I tried to find what exactly can trigger the watchdog. But there can be a lot of different reasons. I guess we need to enable SYS\_DEBUG: ``` SYS_DEBUG(SYS_ERROR_FATAL, "WDT : REASON: %d\r\n", rebootReason); ``` ---

Three out of four gateways we ordered work just fine, but one is in endless reboot loop. Sometimes we can catch it via WLAN, but it stays up maybe one minute before it reboots. Also resetting does not help. Please advise what to do. ---

Can you check if there are differences between working an non working version when you look at lora board version, date/version/revision on main pcb other visual parts etc? Are you willing to swap lora board, power adapter etc to see if the problem move with it? ---

Well, the three working ones are allready installed in a demo system, so no swapping components possible, but I have relatively easy access to one of them so I can take a pic and compare component versions. What should I particulary look at? ---

Is the gateway with updated firmware still stable for you ? ---

The firmware that makes my gateway stable doesn’t exist yet I guess. The fw compiled from src and the latest beta don’t solve the rebooting.
