1.Does this mean the SPI device is OK at TX1 R28.1?

2.But I can not find the SPI CLK wave signal,WHY?

sudo ./spidev_test -D /dev/spidev0.0
sudo ./spidev_test -D /dev/spidev1.0
sudo ./spidev_test -D /dev/spidev2.0
sudo ./spidev_test -D /dev/spidev3.0

I use the PC0.0,PC0.1,PC0.2,PC0.3,PC0.4 to SPI pin.

How can I solve this problem?

2

Not sure if this comment send package?
Can you try have parameter for the data package.

3

What the parameter for the data package?

How can I send a large data pakage? for example ,50 bytes.

Download below execute binary and try “./spidev_test -D /dev/spidev0.1 -s1000000 -g8 -b8 -p0 -n1 -zzz -t”
