ESP32 Forum

Hello, I have a problem in an esp32 that crashes and reboot every ~10h for an irs interrupt without writing the problem: I tried to change the interrupt watchdog timeout from 300ms to 1000ms or to 50ms without noticeable differences.
I also enabled the core dump from menuconfig, but nothing is printed before the reboot.

How can I have information regarding the problem that blocked the interrupt?

I have different tasks running on the device, but most of the code is running without interrupts. The device is communicating with an UART device, connected to wifi and sending information to an MQTT broker.

Thanks

Hello,

I am also trying to find an WiFi issue, I get
rst:0x8 (TG1WDT_SYS_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)
when running esp-idf example softAP.
Working on ESP32WROOM powered with LSH14 battery and buckboost, I can send MQTT messages with a SIM7070 Modem, so I don't think it is a HW problem (since modem can take 2A peak).
Aim is to work in deepsleep mode but no display so all configurations will take part on webserver.

Rebooting...

I am applying 3.6V on VIN with 1A limit on a power supply so it can't come from power supply I guess.
I am now clueless (ESP IDF v3.3.5), flash erased all cleaned....

Any suggestion?

Still sounds like a power issue, to be honest...

I am applying 3.6V on VIN with 1A limit on a power supply so it can't come from power supply I guess.

VIN? Of what devboard? Many devboards have a regulator that requires a larger voltage difference between Vin and the output 3.3V. For instance, the AMS1117 common on most devboards requires 1.15V, meaning the board may not work right if Vin is smaller than 4.45V.

Hello ESP_Sprite,

well I have a power supply set on 3,5V with current limit 1A directly on 3V3.
We are making various custom PCBs with ESP32WROOM. On one of the last boards I have cut all lines from ESP32WROOM, so there are only RX0,TX0, BOOT, EN and supply (3V5 on 3V3 because there is also a modem, now unconnected, which need some more voltage).
I never had this WiFi problem before .
Now I am only trying softAP and Station example from esp-idf-v3.3.5 (all other functions like deep sleep, wakeup, timer, ulp co pro, uart und touch are working fine).
Result are:

I have already made erase flash, cleaned, played with menuconfig... with no success.

and I get often this last thread:

and then nothing happens anymore...

What alos weird is, is that the next task (just print a timer counter) doesn't fired, as if CPU hangs in wifi_start():

Hello,

I rechecked all voltage levels with & without buck boost, I have now fixed 3.5V on ESP32 (max 3.6V in datasheet).
I could connect twice to softAP but Wifi makes all system hanging and I can't see anything on monitor just frozen.

Every clue is now welcome after third day of debuging...

Do you have enough decoupling on your voltage lines? Especially with a slow-reacting power supply, putting a few uF near the ESP32 itself may help.

(Also, only just saw you're using ESP-IDF 3.0 - that one went out of support a while ago. Not saying it'll solve your issue, but you may want to think of changing to a more recent version.)

Hello ESP_Sprite,

I will double capacitor then. What I have seen is that :
- when I only pull EN down to restart ESP, wifi task will freeze (same behaviour after deep_sleep wake-up)
I can see garbage in monitor
I (5749) wifi:mode : softAP (ac:67:b2:4a:ef:f1)
I (5749) wifi:Total power save buffer number: 16
I (57������fi:Init max length of beacon: 752/752
I (5759) wifi:Init max length of beacon: 752/752

- when I shut the power supply down and let capacitors discharging under 3V, wifi will work when I reactivate the power supply.
Here is the monitor clean
I (5869) wifi:mode : softAP (ac:67:b2:4a:ef:f1)
I (5869) wifi:Total power save buffer number: 16
I (5869) wifi:Init max length of beacon: 752/752
I (5869) wifi:Init max length of beacon: 752/752

My EPS-IDF is v3.3.5 (I reedit the subject name)
