TMC2208 V3.0 on SKR1.3 ALL LOW error

Today I upgraded the main board to BTT SKR 1.3 with BTT TMC2208 V3.0 in UART mode, with the latest Marlin 2.0.X firmware and MKS TFT28 V4.0 display. I have the following issue with this setup:

• if I run M122 in Pronterface I get ALL IN LOW error message on all axis

• if I move the motors from Pronterface they move 20 mm instead of 10 mm
• if I auto home X first the Z hoes up 20 mm and the it homes X.

What I have done already:
On the board I have set the jumper on INT-5V. I have jumpers on the UART pins. All the other jumpers are removed. I didn't soldered the pads on the bottom of the TMC2208. In Marlin the drivers are set to TMC2208 and the e-steps are 80.80.400, 95

Please help.

Standalone and uart weld picture is not clear

Hi

according the pdf. the pictures about weld the J2 pads for switch standalone drivers to uart drivers is not clear at all

what is the standalone, and what is the UART picture?

i can assume the left picture is the standalone version, and the rigth the UART version?

if the v3.0, not have asigned the work mode*, what is the state of the J2 pin? all J2 pads unweld?

greetings
