I'm having the same issue with my BTT GTR 1.0 and BTT TMC 2208 V3 UART.
But my issue is only on the X axis.
I've also tried swapping drivers but no success.
Here's my TMC DEBUG Output:

@hiperlouro i changed boards, then swapped the drivers around and got x to read normal. I think it might be a stepper issue ?
Although i had tried that on the other board and it didnt seem to help so could be a combo issue as well
I've received the ALL LOW error message every time I boot my BTT GTR1.0 board that is running Marlin 2.0.7.2. But so far the board seems to function OK. It has TMC2208 stepper drivers installed. I've done everything I can think of to find or identify the cause of this error message, but have found neither a cause nor a solution. What I have found is that people have been seeing this error for at least a couple of years.
Today I used VSCode to search all of Marlin (and maybe PlatformIO too - I'm not sure how VSCode does it's searches) for the text "ALL LOW" and found nothing. So maybe the error is coming from somewhere else? I'm using a BTT TFT70 screen to communicate with the GTR 1.0, so maybe there is something going on with it - the TFT 70.
So i have a BTT GTR v1.0 and 6 BTT TMC 2208's V3.0 UART's
Now the problem is . 4 test with no errors 2 test with errors.
Firmware: Marlin Version: CONFIGURATION_H_VERSION 020008

I have tried Swapping the steppers but the X and E0 still have the same error so its not the steppers its either something on the board or something in the firmware.
