Zephyr on DWM1001C: SPI Problem

I am using Zephyr on DWM1001C board and unable to read its DEV_ID with NRF52832 SPI interface. It seems that DWM1001 does not respond to the SPI request (the API always return 0x00). Could someone tell me the problems?
Here is my code: main_c.c (1.7 KB) .

I’ve figured out the problem. I missed the cs configuration. Here is my new code.
