[GPIO Interrupt]

Thanks for the confirmation. I tried to see if I could quickly search and understand what soft interrupts are. Do you mind elaborating?

I decided to introduce an Arduino Pro Mini in the mix. It interfaces with the GPIO inputs and passes that data on to the UART pins.

Looks like the board I'm using does not support both edge interrupts so it's a non-starter. I am looking to get around this with polling but the work continues!

Edit: Yes I completely understand and that was not my intent! First post and was unsure about where best to post. Thanks!

 

I was looking and couldn't quickly discern the differences in the meson, pnctrl, and gpio changes. I'll keep at it

Hello!

 

I am looking to set up edge monitoring for both rising and falling edges. I can monitor either individually but I cannot activate both edges. I receive:

genirq: setting trigger mode 3 for irq 36 failed (meson_gpio_irq_set_type+0x0/0x60)

 

I have attempted to use mraa-gpio, gpiod, and sysfs all with the same result.

I'm on a Radxa Zero running Armbian 23.5 Jammy (Kernel 6.1.y). Interestingly if I attempt to run Manjaro on this board I can interface with the pins to get the values and set direction but I have no edge detection. Is the GPIO driver in Armbian patched for Amlogic Meson G12A?

 

Hoping I'm posting in the right place! I may cross-post to be sure.

 

Thanks!
