Re: Strange behavior with ground

ESP32CAM_Basic_v0.2.png Schematic above. I made by own device in Eagle, and I didn't do a good job on the schematic footprint, but you can see the pin labels on the outside of the device outline. The order of pins in the schematic footprint is the same as the board viewed from above with the SD car...

Strange behavior with ground

This issue is with an ESP32 camera board. I made a PCB to use as a carrier/power interface. There are three pins marked "GND", and I connected them all together and to the ground of the power input, and it won't boot. The pins on my camera board are (CCW from 5V): 5V GND IO12 IO13 IO15 IO14 IO2 IO4 ...

Re: Interrupt watchdog timer firing

You could be right. I checked, and the cable that worked has a resistance of 0.117 ohms on the V+ line, whereas the one with problems is 0.420.

Re: Interrupt watchdog timer firing

ESP_Sprite, I may have the answer, although I don't understand it. I wanted to cause a fresh crash to make sure I copied everything. I connected the board and uploaded the sketch, and it didn't fail, after hours of spinning. So I suspected the USB cable, and swapped back to one that I was using befo...

Re: Interrupt watchdog timer firing

ESP_Sprite, I decoded the backtrace, got:
0x40089792: vPortReleaseTaskMPUSettings at /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/freertos/port.c line 323
I can't find a file named port.c in my system, should I be looking in github or something?

Interrupt watchdog timer firing

I'm trying to make a simple switch to trigger a home automation script. I have a Hiletgo ESP-WROOM-32 ESP32 ESP-32S. The board says nodemcu and esp-32s on the bottom. I tried choosing board NodeMCU-32S, and Node32s (the latter based on the Hiletgo site), same behavior. I'm using Arduino IDE version ...
