LCD display question

I'm trying to figure out what the LCD display is showing and I'm not too sure where to go to manipulate it. Has someone posted how to do such? This counter counts up to 300n and then the board resets, not sure if it has something to do with when I put it together or if it's a software thing. Image

At the moment LCD is somewhat usable, it probably has potential to get much more powerful once someone develops the code :)

I've added a brief user manual into the header of https://github.com/rusefi/rusefi/blob/master/firmware/controllers/lcd_controller.cpp

As for reset - I've never heard of this, it certanly is not expected to reboot every 5 minutes. The counter should keep going up.

Here is a short video of what it does.

Every time that it hits 300n it resets and while it is plugged into the computer on the tunerstudio it will kick the ecu offline.

Sorry now I see this. No ideas :( does power 5v led on power supply corner of red board blink?

why do you think that it's he lcd that causes reset, not ecu resets the lcd? have you checked logs in devconsole?

PS: do not see power supply LED on the videos. How is everything powered on this video? Do you have same result if powering the board with 12 volts? The way the video is I am not sure if there is a mini USB cable there?

Here is a video of it with power to the board with the USB and 12v power supply turned on. It does the same thing at the sae time interval. Looking at the logs it doesn't show any sort of "oh crap, disconnect" it just resets as if it is losing the com port. But even with it not plugged in it does the same thing. It could be an ECU thing yes, I went with LCD because that's what I was noticing of course.

I have to say I have no idea what could be causing this. Does it happen with only 12v power supply and with both USB cables disconnected? I am trying to eliminate any console or PC magic in general.

Also please forgive me for saying that

Might as well try some random things. Can you update or verify that your STM32 firmware is updated? See link below.
https://rusefi.com/wiki/index.php?title=Manual:Software:User/en#Load_firmware

Also is this a china board? Or an OEM board?

Does the board have any silk screen revision markers or similar?

Do you have any other STM32 boards? Could you verify it's a problem with another STM32 board as well as this one?

See https://rusefi.com/forum/viewtopic.php?f=4&t=394&p=27974#p27974
We recently had something similar with 0.5 boards where one of the resistors on power supply was not populated. But 0.4 and 0.5 power supplies are pretty different.
