Questions related to SPI CS Pins on Duo256

Hi guys

I discovered the milkv boards 2 weeks ago and I have duo256 and intending to try ardupilot in this board running in the riscv core for linux and freertos core for motor outputs. For that, I have same questions related to buses and GPIO.

there is a way to have 1 spi with 2 CS pins ? There is a device tree overlay to set the pinmux?

Thanks

Hi,

after a log of research, I ended using a GPIO pin as a secundaty CS PIN.

Now I have a second question, there is a hardware timers on the Duo I can use?
