Good morning, I have a NanoPi Neo Core that I want to use to generate a PWM wave. As far as I understand, the pin for this is PA5, which is shared with UART. However, by using the corresponding overlay, the UART would be disabled, and PWM would be enabled. Is that correct? What would be the next steps to verify that this is correct and to generate the PWM wave? Is there a specific command to do this? Thanks for your help, and best regards!

Good morning, I am having some problems with the i2c-1 bus, as it sometimes gets stuck even though I have external pull-up resistors. I need to be able to reset the bus to fix it and check the status of the channels, but I don’t know which Linux GPIO corresponds to the physical pins that the kernel associates with PA18 and PA19. I have tried using wiringPi, but it doesn’t indicate this. Can anyone help me? Thanks!

Hi, is posible to add Canbus by a MCP2515 in a spi port ? thanks!

Hi @nagaudio im trying to do the same in a neo core. what changes you do in sun8i-h3-nanopi-neo-air.dts, sun8i-h3-nanopi-neo-air.dtbo? i have to replicate in the sun8i-h3-nanopi-neo-core.dts, sun8i-h3-nanopi-neo-core.dtbo Thanks!!

Hello! How y can try to apply this patch? Thanks! Luis

Good morning, I'm trying to activate PWM by hardware to use wiringpi. I activate the PWM option from Armbian config hardware, but it doesn't seem to have any effect, and UART0 doesn't seem to be deactivated. I'm not sure if there's any issue or if I'm doing something else wrong. The build is Armbian 22.11.1 Jammy with Linux 5.15.80-sunxi. Thanks for the help!
