WDT Reset Issue While Flashing #16

Open dj095 opened 7 years ago

dj095 commented 7 years ago

There is one thing i would like to ask you @pfalcon :

I took a working copy of micropython ota build 1.8.7 from the downloads page of micropython. And flashed it onto my esp12F Module. It works fine by the way. Then i used the .ota file that was digitally signed with with same key as the micropython .bin file. Then i used your ota_client.py script and ran it with the .ota file when the ota-server was listening(OTA Mode). The .ota file was signed with same digital signature as included in the config file for the ota_server. So the server started picking up the digitally signed packages and after a while a reset happened due to the WatchDogTimer(WDT Reset). Then the rest of the packages didn't go through. It says "Unexpected offset". Of course the offset that the ota_server expects now is 0 because it restarted. So I studied your code for ota_server and found a line wdt_timer_feed() to keep the WDT fed. I want to incorporate this line in your Server loop when its receiving UDP Diagram packets. So i how can i incorporate this change such that its supported in the micropython esp8266 1.8.7 code ? And will this change actually stop the WDT_Timer while receving packets?

Thanks for submitting a separate issue to the right project, but:

And will this change actually stop the WDT_Timer while receving packets?

Sorry, I have no idea. You will need to try and see yourself if it helps. Generally, the fact that you get a WDt reset isn't good. It shouldn't happen, and neither myself not @dpgeorge who tested it too saw it. There can still be a bug in ota_server of course. Or there may be some issue with your hardware (check power, etc.).

Actually i did a bit of research and i found that this is actually the "smart-config" in esp12 type boards. They keep the WDT enabled by default so if some corrupt firmware flashing happens and the board resets after a while due to WDT and prevents the board from getting unusable. Anyways i am ready to test this on my own but i don't know how to include any change in your project and get this change in the micropython firmware i build from the official site. How do they include your ota-server implementation in micropython which is visible in example- micropython 1.8.7 ota build. All the echo messages are the same as in your ota-server. But i could not find your files in the micropython repository. Could you help me on this?

Please tell me how to include some change in your repo in the micropython build image. I can't find your files there.
