How can test the SPI port clk clock at TX1 R28.2?
what command I need to run ?

2

Try the spi_tests utility should be like spi_test -f 600000

I can not use the "-f"flag.

nvidia@tegra-ubuntu:~/spi$ sudo ./spidev_test -f 600000 
./spidev_test: invalid option -- 'f'
Usage: ./spidev_test [-DsbdlHOLC3]
  -D --device   device to use (default /dev/spidev1.1)
  -s --speed    max speed (Hz)
  -d --delay    delay (usec)
  -b --bpw      bits per word 
  -l --loop     loopback
  -H --cpha     clock phase
  -O --cpol     clock polarity
  -L --lsb      least significant bit first
  -C --cs-high  chip select active high
  -3 --3wire    SI/SO signals shared
  -v --verbose  Verbose (show tx buffer)
  -p            Send data (e.g. "1234\xde\xad")
  -N --no-cs    no chip select
  -R --ready    slave pulls low to pause
  -2 --dual     dual transfer
  -4 --quad     quad transfer

How can I fix this?

Sorry should be the -s

How can I use spidev_test to send out some data?
for example I send out 10000 bytes.

-p for data pattern but for your case you may need to modify the program for it.
