Board does not work with UART #1

I have the SGen L V2 and I cannot get UART mode to work with the mks tmc2209 drivers. I have added the jumpers in the correct configuration for uart under the driver as well as configured marlin with uart and m122 enabled. Running m122 returns a bad response on all the drivers, meaning they are not connected with uart.

This was no longer a problem when connected to a proper power supply, I was having this issue exclusively through usb. Closing ticket
