AtomS3R - Black screen with UIFlow2 firmware (Backlight works, no image)

robski

@10sor have you tried any of the old uiflow2 firmwares from m5Burner list - I mean very old like 2.2 or 2.1 will this give you operational display?

@bschwahn The format that I used when posting was created using Chat.M5Stack.com

I have StickC-Plus2 and it works as expected in UIFlow2.0 with the same cable and the same port.
The official M5Burner list only has UIFlow2.0 for AtomS3R.
I have tried WebBurner (without USB connection) for flashing firmware and had the same result: no errors or warnings, but the screen is still black.
I have tried v2.4.1, v2.4.0, v2.3.1, v2.2.1, and v2.1.4.

I don't want to spend a lot of time looking for a solution anymore, but if I find one, I'll let you know here.

@robski Yes. I have tried v2.4.1, v2.4.0, v2.3.1, v2.2.1, and v2.1.4. The result remained the same.

@10sor any arduino projects (if tried) with same result - no functional display?

10sor

@robski I have tried display example. The result still the same: black screen (backlight works, no image).

@10sor wow, and factory demo works fine...
i2c address issue?
library issue?

10sor

To test other functionality, I connected Unit Relay and ran a test program. It works as expected in UIFlow2.0

BTW I found that Arduino Lab for MicroPython can be used as a simple IDE for programming a device with UIFlow2 firmware.

@10sor I do have one of Core Basic controllers which one day after loading project decided to not display a thing, all other bits are ok just nothing on the display since.

Found this post when I googled, I got an AtomS3R yesterday and I have the exact same issue with the display.

Pretty much what @10sor said. Backlight is on but nothing else shows on the display. Tried with UIFlow2 and the examples in Arduino IDE. I've reflashed and reset multiple times, always the same result.

Factory demo works without any issues. The Env III sensor also works, I got output from it in UIFlow2 but the screens is black at all times.

@10sor
Thanks for the feedback, this is indeed a very strange situation.
Could you please provide us the SN number on the package? So that we can check if this is a problem related to specific batch.
