I got much problem for to communicate with this driver.
TX-RX from MCU are conntected to the same port "PDN_UART" separate only from 1k resistor.
Obvisiuoly when i trasmitt some data i get a eco, but iexpected also a answer from the driver, instead no.
I tried to connected with Real Term and a board FTDI for to undesrstand better like this driver works,
I sent this command:
0xA0 0x00 0x22 0x00 0x00 0x4E 0x20 0xC3
A0 → Sync nibble
00 → Address node
22 → Register VACTUAL
00 00 4E 20 → Value 20000 in hex
C3 → CRC
I got only the eco like answer. The motor is "off"
Anyone can help me?

Do you have UART jumper enabled on the TMC2209?
No i don't see jumper, for uart mode does it need a hardware setting?
