Stm32mp157 SPI A7 example

[cfilipescu]

I am looking for an example using spi6 which is only accessible by A7 core. Explicitly how to enable it in the device tree and a quick example for sending a byte.

Hi @cfilipescu​ 

For Device Tree setting I guess following pages might help :

https://wiki.st.com/stm32mpu/wiki/SPI_overview

https://wiki.st.com/stm32mpu/wiki/SPI_device_tree_configuration

For quick test you can use the Linux kernel spidev_test tool, source code can be found under tools/spi in Linux kernel.

Hope it help
