Can anyone help get me get OpenWRT installed on a Reyee AX3200? It looks like someone has come up with a high level process however it's a little above me. https://github.com/openwrt/openwrt/pull/10951 specifically steps 1 and 2
Serve the initramfs.img using a TFTP server with address 10.10.10.3. - Where can I get the initramfs.img?
Interrupt the uboot startup process via UART. - How do I do this?
To get the initramfs image you need to build the openwrt image first ( since your router's model isn't available for support in official openwrt builds... )
You can further check out these tutorials for building an image for your router manually.....
You'll open the case and connect to the Serial header with a TTL 3.3 V serial cable. Usually the display will instruct you to press a key to stop boot.
