Spidev crashes when SPI_IOC_MESSAGE(N), N > 1

Hi, I am also working on SPI between Jetson Xavier NX and ADIS16480.
I recommend you to use the hardware delay. Please have a look at low level document and find this part:

I still have a problem and asked it here:

Hardware CS control in SPI

By the help in this forum, I can put a small delay between packets in the SPI communication. The test code sends 35 16-bit packets with 8-clock delay between them.
