CC6UL accessing gpio's and other peripherals

0 votes
Hi community,

I want to know if there is any example code on how to access a gpio in the connect-core 6ul, i understand how to use an i2c device but i don't understand how to use the gpio interface neither the spi. I've been reading general kernel documentation about gpio's but only mention how to access using the sysfs interface; any documentation on how to interact with the hardware available would be helpful.

Sorry for the newbie question,
best regards.
