BG77 SPI with EVB (Evaluation Board)

I’m trying to use an eink display with the SPI protocol but I can’t get it to work I always get the error QAPI_SPIM_ERROR_OPEN_FAILURE. Is this error due to the connections or do I have something wrong configured?



pls check the SPIM_mode first , it determined by slave device and clk freq
