Testing SPI on Apalis TK1 Eval Board

I am attempting to verify the functionality of the communication ports available on the Apalis TK1 eval board.
I have been unable to run the loopback test described here: SPI (Linux)

When running spidev_test I receive the following response rather than the transmitted hex values.

./spidev_test -D /dev/spidev0.0
spi mode: 0
bits per word: 8
max speed: 500000 Hz (500 KHz)
can’t send spi message: Invalid argument

Looking in /dev, the following devices are available: spidev0.0, spidev1.2, spidev3.0

Thank you

hi esilva

Which bsp version are you using?


By default SPI on tk1 can’t run with 500 kHz frequency try using min of 6MHz

Thank you very much dominik, that change solved the problem
