LilyGO LoRa T3S3 resets when communicating over serial #79

Closed dacwe closed 2 months ago

dacwe commented 2 months ago

Describe the Bug After flashing to LilyGO LoRa T3S3 V1.2 (20230720) and resetting the board manually the serial port cannot be opened. 

[14:51:39] Please take the board out of flashing mode by momentarily pressing the RESET button.
[14:51:39] Hit enter when this is done.

[14:51:56] Opening serial port /dev/ttyACM0...
[14:51:59] Serial port opened, but RNode did not respond. Is a valid firmware installed?
write failed: [Errno 5] Input/output error

Trying to open the port manually by calling cat /dev/ttyACM0 also resets the board.

To Reproduce

  1. rnodeconf --autoinstall --baud-flash
  2. Choose [9] LilyGO LoRa T3S3 and [2] 820 - 1020 MHz (with SX1262 chip)
  3. Put the board into flashing mode and wait for flash to finish
  4. Reset manually

Expected Behavior Serial communication works and does not reset the board.

System Information

Tried installing on a second board. Same error, boards have the same version but different (production?) dates: 20230720 and 20230530.

I have never seen that board configuration before. The breakouts next to the battery connector aren't present on the V2.1 or the T3S3. It's possible some changes have been made that affect the firmware (the T-Beam had a power management module changed in a recent revision that needed a new library altogether).

I suggest checking the CE firmware repo, as this is mostly legacy firmware: https://github.com/liberatedsystems/RNode_Firmware_CE

Here's a pertinent topic from that repo: https://github.com/liberatedsystems/RNode_Firmware_CE/issues/12

Since I'm not a firmware guy, I can't be of much more help, but you should get a pretty quick response in the other repo.

Thanks for the quick reply! I will close this one out!
