Describe your issue:

We have problems with FYSETC ERB v1.1 board for ERCF.

If we flash firmware with option Flash chip (W25Q080 with CLKDIV 2) board boot only once after imediate flash and reboot. After power off/on we can’t achieve USB connection even if we tried with pressing RST/disconnecting/connecting.

If we flash with option Flash chip (GENERIC_03H with CLKDIV 4) board boots OK every time, but is unusable, if we send any commands to it, it almost every time stops with
Timeout on wait for 'tmcuart_response' response (log for this case is attached)

We are using latest available klipper version.

The same problem is being addressed here:

We tried everything we could think of, but to no avail.

Has anyone encountered a similar problem and managed to resolve it, please?
