Hi OpenWRT team, could you provide firmware support for TP-Link Deco M4R mesh router?
Adding support for a new device usually requires to have the device in question on the desk, opened up, with a serial console attached and spending somewhere between a long rainy weekend and several weeks on first checking what the OEM firmware does and what the hardware needs, before being able to go over to testing initramfs images and finally developing support for flashing it (after having reverse engineered what the OEM firmware/ bootloader accept). At this point, you're the only one with this hardware (or the motivation to buy it), so you'd be the the only one in a position to do the steps above.
most more regular developers would look into ipq4018/ ipq4019 based devices for this purpose, much newer/ faster hardware for similar prices, so the M4R is not a particularly attractive target to buy.
I know its not too much, but +1 for OpenWRT on TP-Link Deco M4R.
