December 21, 2025Dec 21 Hello! I've built my own sbc using the Allwinner H3 chip, and I'm looking to get a custom armbian image running on it. I've already successfully compiled an image by adding a new config to u-boot and armbian-build, and a device tree to the linux kernel. Now I'm looking to get the WiFi working, but I can't seem to find where I can change its pin definitions. I'm using the AP6212: the SDIO pins are connected to SDC1 (aka mmc1) like every other board, but the WL_REG_ON (aka WL-PMU-EN) and WL_HOST_WAKE (aka WL-WAKE-AP) pins are connected to GPIO pins different from all other boards, so I'll need to change their pin assignments in the kernel manually. But I can't find where are these pins defined! Do I need to change it via u-boot, the kernel, a module or some config file? Any pointers would be appreciated! Thanks in advance
