New out of the box t beam. I used the meshtastic flash tool after soldering led screen.
After flashing 1.2.55.9db7c62 “Critical fault #6”
Now displayed on device. Is it possible to repair?
Which firmware did you flash, that error means that the power supply chip is not found, the .7 version does not have that chip, the 1.1 does.
Hello, version 1.2.53 is flashed on the board. I have a batch of 4 boards the error is only on one.
The Printed circuit boards all look the same, is a revision number printed on the board?
.7 has a slide switch for power 1.1 a push button
Critical fault 6 means we can’t communicate with the power management chip. If it works on 3 and there’s a problem on one, it’s like that’s where there’s a problem.
The boards have the push button power buttons.
I may take a look at the schematic, has anyone tried to to swap a component?
