MKS SGEN_L V2.0 + MKS TMC2209 V2.0 Testing X connection... Error: All LOW

[sag3ll0]

I have an MKS SGEN_L V2.0 board with MKS TMC2209 V2.0 drivers, the board is configured according to the instructions , as the basis, the firmware is used from here The drivers are connected in uart mode. 'TMC_DEBUG' mode is enabled. When the code is requested, M122 returns the following result

Set TMC uart mode, you need set it

1. Use jumpers connect uart

2. In Configuration.h file, define driver type is TMC2209

   define X_DRIVER_TYPE TMC2209

   define Y_DRIVER_TYPE TMC2209

   define Z_DRIVER_TYPE TMC2209

   define E0_DRIVER_TYPE TMC2209

3. You need connect DC power for the board

1. Use jumpers connect uart

2. In Configuration.h file, define driver type is TMC2209

3. You need connect DC power for the board external 12v 6a with mks-pwc (not usb)

all this info in attached MKS_issue_data.zip arch

yes, it really works, my mistake is that I looked at the instructions wrong.
