Connecting orange pi to BIGTREETECH-SKR-mini-E3 v3

[hot rain]

I'm trying to connect orange pi zer o3 to btt skr mini e3 v3 via UART. I compiled klipper for Serial (on USART2 PA3/PA2) and i connected orange pi rx pin to tx2 of btt and tx to rx2, but im getting error mcu 'mcu': Unable to connect Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Error configuring printer I tried every Uart port taht shows up in fluidd

It seems like there might be an issue with the UART communication between the Orange Pi Zero and the SKR Mini E3 V3. Here are a few troubleshooting steps you can try:

1. Check the wiring: Make sure that the RX pin of the Orange Pi is connected to the TX2 pin of the SKR Mini E3 V3, and vice versa. Double-check the connections to ensure they are secure and not loose.

2. Configuration settings: Ensure that the UART settings in the Klipper firmware match the physical connections. Verify that the baud rate, data bits, stop bits, and parity settings are correctly configured.

3. Power supply: Make sure both the Orange Pi Zero and SKR Mini E3 V3 are receiving adequate power supply. Insufficient power can result in communication errors.

4. Ground connection: Ensure that the ground pin of the Orange Pi is connected to the ground pin of the SKR Mini E3 V3. A common ground reference is essential for reliable communication.

5. Check for conflicts: Make sure that no other software or service...
