How to use two SPI busses with CB1 on Manta M8P

Reversed MOSI/MISO and got:

Klipper meldet: SHUTDOWN

Internal error during ready callback: Invalid ads1220 reset state (got [0xff, 0xff, 0xff, 0xff] vs [0x0, 0x0, 0x0, 0x0]).
This is generally indicative of connection problems
(e.g. faulty wiring) or a faulty ADS1220 chip.

Reversed MOSI/MISO again and keeps the same.
May I’ve roasted my ADS already?
