"wdt reset"

[kim-rok]

After flashing ESP, broker startting message displayed. And then configure loaded. after a moment, ESP go to 'wdt reset'.

Any help?

Thankyou for PWM!

Happens sometimes for me with unstable power supply. Good power supply and a larger capacitor between GND and Vcc may help. Or only with this firmware version? If you download the FW binary make sure you don't corrupt the file (e.g. ASCII mode).

Hi I used the bin files to write to a Wemos d1 using nodemcu master flasher. Everything went ok but when I reset the wemos I get this:-

This just continues to loop. Have I done some think wrong?

No real idea, for me the latest FW seemed to work fine. You might try an earlier version, perhaps this one https://github.com/martin-ger/esp_mqtt/tree/dd4cf9c2da1c9e2fd2b6c26a3192005be40ebaee - this is known to work fine for others. Currently, I'm on a trip. Will test, if I can find any problem with the latest build on sunday.

Thanks for the reply Martin

I uploaded the older version from your link and had similar result to the newer firmware:-

I then loaded your esp_wifi_repeater to the same wemos and that worked ok, so I know the wemos is good and the way I upload the firmware is good to.

Not sure what to do now, Hope you can help when you return.

Another idea what might be wrong: perpaps the flash read of the script fails, beause there is something in the memory from previous firmwares. Clould you try to erease flash memory at 0xd000 by e.g. flash this empty bin there: https://github.com/CHERTS/esp8266-devkit/blob/master/Espressif/ESP8266_SDK/bin/blank.bin

Will also try to fix this, when I am back tomorrow.

[Gruffnco]

Thanks for that Martin, writing the blank.bin file has sorted my problem.

Keep up the good work, you have some great projects.

Regards Gareth
