Check this for the MTK-based devices, as my work has only been with the QCA-based devices!

My notes show that, for the GL-AR300M, if you don’t want to use the GUI (my build machine is headless), you can use

curl -X POST -F nor__firmware=\@_tmp/ar300m-nor.bin http://192.168.1.1/index.html

or, for NAND firmware

curl -X POST -F nand_firmware=\@latest/OpenWrt-2019-06-04_1156-0700-ath79-nand-glinet_gl-ar300m-nand-squashfs-factory.img http://192.168.1.1/index.html

The proper parameters can be determined by looking at the U-Boot upload page’s source, or by

$ curl http://192.168.1.1/
