TP-Link seems to have rebadged these, and are also selling them as Festa FR365.

did you achieve a serial connection?
seems mine has the tx rx locked.
could this be a software problem or does it need some sort of bridge soldered to the board?
On the face of it, you may need to bridge R150(?) and R181 - and remove R195. I may be wrong.

Has anyone been able to make progress on the ER706W?
@slh your right
r195 is a resistor between the ground and the RX on the board.
r 181 and 150 should be bridged but i cheated used ide wire straight to the RX and TX.
pinout of serial is
pin1 TX
pin2 RX
pin3 Ground
pin4 VCC
thats right to left.
serial setup is 115200 8 1 N 3.3v

Serial log says OEM fw is a knockoff OpenWRT 22 mtk sdk adding wifi drivers.
Can you break into u-boot and check like help ? commands to see if we can boot from network tftp or so?

tftpboot is there so initramfs image is possible .
what i noticed from the boot log is the names of the partitions are different i think uboot is looking for a rootfs but the names are something else.
the sorcecode appears to be in imortal openwrt form.
here is the help from uboot & printenv.

Got this from above but does this mean ethernet wont work?
Tried a initramfs image from imortalwrt (kernel 5.4 like source code)for a test i thought was safe enough to try.
tftpboot couldnt see the server via ethernet it just timed out.
could it be a setting needs changing or adding?
computer with the tftpserver cannot see a connection either.
Yep source code is barrier breaker but at kernel 4.5.
wifi drivers not sure i haven't done anything with sdk.
Uboot does ubi can the mtd partitions be copied and tftput back to my computer?
To turn on the ethernet port the command in uboot is
enable_phy
i have got it booting as a filogic device with no source code used.(with ethernet)
every time i add it as a new device no ethernet or kernel panic.(think im having trouble adding the 7531 switch driver....
