We used Mini SAS cable to connect SBC with CP213x. Two type cables are compared. The cheaper type cables randomly throw the error when call SLAB_USB_SPI.CP213x_SetSpiControlByte, while the expensive cable never throw this error. Why?
Thanks in advance.
Thank you for your answer.
The pictures of two cables are attached.
Could you explain what happened when SPI throws USB_SPI_ERRCODE_CONTROL_TRANSFER_ERROR?
