陳柏儒 Posted October 12, 2023 Share Posted October 12, 2023 Hello, I tried ` echo 463 > /sys/class/gpio/export ` and it build gpio464 folder under /sys/class/gpio , and I cat `value` file to check gpio status. It seems not work. The same gpio was working on Bananapi official debian and Ubuntu mate image. How can I solve this problem? Thanks 0 Quote Link to comment Share on other sites More sharing options...
陳柏儒 Posted October 13, 2023 Author Share Posted October 13, 2023 (edited) I solve this issue. Because in Armbian image, GPIO pin map as same as Khadas VIM3 (https://docs.khadas.com/products/sbc/vim3/applications/gpio/mainline-linux-table) I use GPIOA_3, the pin number is 479 not 463. PS. Armbian gpio pin num need to use "mainline linux table". Edited October 13, 2023 by 陳柏儒 0 Quote Link to comment Share on other sites More sharing options...
