STM32MP257F-DK Yocto SPI

[nh7]

Hi,

I have STM32MP257F-DK and Yocto linux installed to it.
I have tried to get spidev working on SPI6, but no luck so far.
/dev/spidev6.0 won't appear to filesystem.

Has anyone tried this combo and got it working?

Any working SPI configuration would be highly appreciated.

Hello @nh7 ,
What did you do to make spidev work on your system ? 
spidev would certainly need a device tree modification with a specific compatible to get a new entry in sysfs. 

Please take a look at the way to process here: https://wiki.st.com/stm32mpu/wiki/How_to_use_SPI_from_Linux_userland_with_spidev

Kind regards,
Erwan.
