Hi. I downloaded the kernel firmware, but unfortunately nothing worked. I configured the config according to the instructions, set the data auto upload parameter in DGUS. when the sensor is pressed, nothing is transmitted to the port. Changed ports from UART2 to UART4, nothing. At the same time, it accepts commands correctly.

Uart 2 has enabled "automatic data upload". Did you download the wrong file? Can the screen and PC communicate normally?

Yes, I can interact with the screen from a PC. it accepts commands, but there is nothing in response. I can send any commands through SSCOM, everything is ok. But there is still no data from the screen when the sensor is pressed

Please upload the program on the screen and the screenshot of the communication between the screen and the PC.

I sent a command through the USB-UART1 adapter built into the display, received a response from the display:
5A A5 06 83 00 0F 01 51 10
By sending your command via UART2, there was no response from the display.
