Strange "wdt reset" #5

Closed enavarro222 closed 8 years ago

enavarro222 commented 8 years ago

Hi,

I'm testing it with a nodeMCU 0.9, I got the following log:

Boot in config mode, ok. Then I send json config and :

Received config request
✔ Configured

 ets Jan  8 2013,rst cause:2, boot mode:(1,6)

 ets Jan  8 2013,rst cause:4, boot mode:(1,6)

wdt reset

I reflash the FW, it boot in normal mode. Then when I manually ask for a reboot in config mode:

** Booting in normal mode **
Attempting to connect to WiFi
Attempting to connect to MQTT
Sending initial informations
Temperature: 22.00 °C
Resetting
↻ Rebooting in config mode

wdt reset

I use mosquito as MQTT broker.

Maybe some delay() should be added to handle wifi processing ? or mqtt.loop() ?

The issue comes from the Arduino for ESP8266 (see https://github.com/esp8266/Arduino/issues/1017) Basically, an ESP.restart() after a flash triggers a wdt reset.

To confirm this is the issue, try this:

Flash the firmware
Manually power reset the board
Repeat the config request/reset

You will see that the board is actually rebooting.

marvinroger commented 8 years ago

Note that when stuck on a wdt reset, you don't even have to reflash the firmware: just reset the board manually and it will boot in the correct mode.

enavarro222 commented 8 years ago

Indeed, this doesn't appear when I hard reset power of the board after flashing !

We can leave this ticket open for documentation, until bug isn't fix in Arduino/ESP8266.

Resume: ~~With NodeMCU 0.9~~ for every ESP8266, you need to manually power reset the board after flashing to have reboot working.

enavarro222 commented 8 years ago

I'm not familiar with nodeNCU, Is there a way to reset it without plug/unplug it ?

marvinroger commented 8 years ago

Yes, let's leave it open for reference. It is not only a problem with NodeMCU, it is for every ESP8266 ;)

On NodeMCU 1.0 there is a RST button. It seems like NodeMCU 0.9 doesn't have such a button, so you'll have to power reset it!

Ok, thanks for the quick answer !

Dear alll... I use a Nodemcu v.09 and v.10 i did have have work my esp correct. after a new flash i did have a problem with the esp... wdt reset load 0x4010f000, len 1264, room 16 tail 0 chksum 0x42 csum 0x42 ~ld ªU INIT : Booting Build nr:48 WIFI : Connecting...

I try different reset option...[ 10k to gpio0 gnd to reset, reset button different ways.. ] I do have 3 esp boards and all 3 broken, when i did flash wit espeasy R48, ide 1.6.5

Is there some one that have working option for this problem?

marvinroger commented 8 years ago

@Dylantje report your issue at esp8266/Arduino, this is not the place to do it as Homie has nothing to do with it. ;)

marvinroger commented 8 years ago

The v2.0.0 will rely on the 2.3.0 version of the ESP8266 for Arduino. This problem is solved in this version.

Eventhough, this bug has be closed sometime ago, here an observation, which might help others: I had the following added to my platformio.ini and I observed the resets described above (about 5 s after startup). After I have removed the debug options, no more resets:

build_flags = -DDEBUG_ESP_PORT=Serial -DDEBUG_ESP_SSL -DDEBUG_ESP_TLS_MEM 
 -DDEBUG_ESP_HTTP_CLIENT -DDEBUG_ESP_CORE -DDEBUG_ESP_WIFI -DDEBUG_ESP_HTTP_UPDATE
