I was excited to find WNDR4700 is supported, however after installing "lede-17.01.4-apm821xx-nand-WNDR4700-squashfs-factory.img" I found the USB3 ports do not work. This is a problem as have a USB drive which I use for dlna.
The forums showed me that I need to install "uPD72020x-firmware_2_powerpc_464fp.ipk" but none of the links work and it cannot be found on the internet.
Does any have a copy of "uPD72020x-firmware_2_powerpc_464fp.ipk" ?
Alternatively, is there another way to active the USB3 ports? I've tried copying K2013080.mem to /lib/firmware and rebooting modem, but no luck. If I run dmesg, I get the error message "xhci_hcd 0000:45:00.0: firmware failed to load (-2)".
