I am using Klipper firmware for Fysetc S6(version 2.1) board. I installed Fysetc S5160(version 1.2) driver to X and Y driver sockets. I am getting "Unable to write tmc spi 'stepper_x' register GLOBALSCALER" error in both slots. 4 jumpers are installed on bottom positions as described in the README. TMC 2209 drivers work in these sockets with UART configuration. I tried 4 different 5160 drivers so this shouldn't be a faulty driver issue.
Klipper docs say that this error might be the result of shared SPI bus:
Note that if the driver is on a shared SPI bus with multiple devices then be sure to fully configure every device on that shared SPI bus in Klipper. If a device on a shared SPI bus is not configured, then it may incorrectly respond to commands not intended for it and corrupt the communication to the intended device. If there is a device on a shared SPI bus that can not be configured in Klipper, then use a static_digital_output config section to set the CS pin of the unused device high (so that it will not attempt to use the SPI bus). The board's schematic is often a useful reference for finding which devices are on an SPI bus and their associated pins.
I looked at the schematic but I couldn't find out if the SPI bus is shared. Sample config file for F6 has a static_digital_output section but sample config file for S6 doesn't have it so I am not sure.
