"Critical Fault" printed on the screen

Support
1

So for sometime we’ve been testing for various bits of busted hardware on boards. But we weren’t ever showing the user this information. Starting with the next device firmware release (in a couple of days?) there will be a new screen which will pop up if we think something is busted.

If you see the following screen, you’ll be directed to this forum (where hopefully you’ll find this post). In this thread more experienced users/volunteers can help debug what is wrong (or hopefully you’ll find an existing answer).

For a list of the numeric fault codes and their meanings see CriticalErrorCode.

These errors seem like the classic iPhone fingerprint errors!
With the difference that in meshtastic these errors are functional instead in the iPhones they are to screw the customer :grinning_face_with_smiling_eyes:

Just flashed a new pair of tbeam boards. One of them came up with a Critical fault #3. No LORA radio.

Give me a clue guys? The rest of the displays look OK.

It is late here. So I will run some more tests tomorrow. Any suggestions in the meantime.

Thanks

You could closely inspect the board to see if it looks like all the components are present and the solder connections look ok. You could just have a bad board, the radio chipset could be damaged.

Welp, congratulations! I’m glad/sad that you are the first person to ‘find’ this feature. This means one of two things

  • either the wrong load for your board type is installed
  • the hardware is actually broken (we tried talking to the radio chip on spi and it didn’t answer)

I might be able to add a little more detail if you could add the following: a picture of your board. Also, if you could capture the first 100ish lines after you press the reset button there might be other clues I could see. (use a serial terminal at 921600 baud)

Looks like the radio is fubar.
Is it worth a reflash?

I have done six of these now and this is the first to fail… This pair arrived out of the blue weeks after the initial four. Only ordered four and have not been charged for this pair yet!

A comment in the missing antenna: You should never power up a device without the antenna attached. This could damage the chip.

So my question is: Was this faulty device powered on much longer than your other device which came up without a fault?

Your HW-version seems correct, but it’s always worth reflashing your device

8

I thought the 1.1 version had antenna protection. But that is no excuse. Having held a full amateur radio licence for over 50 years I admit I should know better. Reflashing did not work. I will not bin it right away. I have a friend nearby who is good at SMD rework. Can anyone point me at a source for bare TTGO SMD modules?

9

I am not really sure about the antenna, but this is what i read so far :wink:

If you contact Lilygo, the probably will send you a refund or replacement.

I don’t know about TTGO SMD modules, sorry. But you could ask your friend to take a look if everything is solderd properly…

Another idea is the GPS antenna, this could short circuit your LoRa antenna with its metal case, which you could check.

I keep getting Critical Fault #5 when one of mine boots up. Any way to clear it? I’m running 1.1.33

11

#5 means it failed when trying to talk to the GPS chip on your board. Does that board give GPS positions later while it is operating? If not, something might be busted on it.

Also - there were some good GPS improvements after 1.1.33, I’m not sure they would be related to this. But first I’d recommend upgrading to 1.1.48.

12

Interesting, it only gave the error when the battery was out and it was powered via USB cable only. I plugged a battery in and took it upstairs from my basement to get a GPS signal after unplugging it. It booted up with no error, got GPS lock no problem. Still on 1.1.33. I’ll update and see if that affects it.

13

hmm - the power for the gps is delivered seperately from the rest of the system (from the axp192 PMU). Perhaps something is busted with the PMU IDK.

14

Hello,

I got a Critical Fault #6 that I’ve had for a while now. I got the board right around the time you posted the firmware version with that feature added. I should have posted sooner but I was busy getting my other 9 units set up (Which all work fine). I already received a replacement unit but if I could salvage this one then that would be awesome.

Using version US 1.1.32

Attached is a picture of the board and the first 100ish lines upon reboot.
Let me know if you need anything else.

Damn, its happening on the replacement unit too.
Didn’t notice it until I connected to serial trying to figure out why the screen wasn’t working.

Is the key message. It means we couldn’t talk to the PMU (power management unit). Either because the i2c bus (which also goes to the oled screen) is messed up or the part is fried. That part can be fried by inserting the battery backwards (which I’ve heard reports of people returning units to amazon after doing that and then amazon shipping them out again). Often when this failure happens, if you power the board with USB and a battery installed you can feel the axp192 be physically hot (which it should never be).

If you have this problem, the board may still work fine - except for one big warning: battery charging may be uncontrolled. I’d recommend quite strongly to not install a battery.

17

SInce this happened on two boards, I recommend you check your screen carefully. Sometimes people buy screens with incompatible pinouts - which breaks the i2c bus.

18

Thank you for the detailed information. All units were bought from Lilygo’s AliExpress page and I’ve confirmed that the pinouts are identical.

I’m fairly confident that I did not install any of the batteries in backwards, but there is always the possibility.
On one unit (post 15), I did accidentally have the display shifted one pin over (gnd, 22, 21, 3.3) so it’s possible that I bricked the board. The display works fine on another unit. I moved it to the correct location before sending those logs, so they’re current. There’s a small chance that there is the slightest bridged connection but nothing obvious, I’ll keep looking. It’s unfortunate that the board possibly died vs the cheaper screen.

I might install the battery and the usb cable to test the chip temp, but let me know if that is a terrible idea.

I don’t think I’ll be contacting Lilygo for another replacement.

I think that would be a fine test. But even if the part doesn’t heat up, I wouldn’t leave the battery in.
