LD2420 triggers boot loop due WDT on ESP32S3 #5705

Open andyvandesand opened 7 months ago

andyvandesand commented 7 months ago

The problem

I'm trying to get an LD2420 to work with an ESP32-S3, the waveshare s3-zero version. As the specific board profile isn't available yet I've already tried changing some paramters, without success. I've tried just the UART without the LD2420, that's working fine. Other pins don't seem to change much either. When monitoring the uart I can see the sensor actually providing valid data, but then the WDT resets the chip.

The sensor is working on an ESP32-WROOM-32E.

Any help would be appreciated...

Totally same issue with esp32c3

fragpic commented 6 months ago

Is the LD2420 connected to the board when you boot it? The LD2420 component has an issue where if no data is seen on the RX pin at boot, it will bootloop. #6594 is supposed to fix it

andyvandesand commented 6 months ago

I just tried without the board attached at all, and it does the same. Going off the fact that the LD actually sends data through the uart until the WDT resets when I monitor it I would assume this is purely a bug in the ld2420 library?

andyvandesand commented 6 months ago

Sorry took me a while to get a local version setup. I can confirm this is at least a partial fix. There is still an issue, in that on every other cold power up the sensor just gets flagged as "failed". Restarting the board seems to fix this. I don't have the required insight to fix this, but I'm very happy to do some local testing if anyone has any info for me.

I believe I too am experiencing this issue with the standard ESP32 dev board and the LD2420. I see the watchdog resetting the ESP part way through setting up the LD2420. This results in a boot loop during programming ultimately ending in the ESP booting into safe mode and thus being undiscovered by Home Assistant.

Hard resetting via RTS pin...

Above is the first instance of the ESP trying to communicate with the LD2420 right after flashing. It does this about 9 times before it boots into safe mode.

I've hooked both UART0 (programming/logger) and UART1(LD2420) up to a logic analyzer and can actually see the LD2420 response traffic on initial programming and if I power cycle the ESP after attempting to program. For some reason I can't seem to get the logger traffic to appear on a Serial monitor that isn't the one provided by ESPHome. For example : tio -b 115200 /dev/ttyUSB0 just results in an empty monitor when I restart the ESP.

This is the yaml I am using to program the ESP:

It is the boiler plate given on the ESPHome page for the LD2420.
