Planex MZK-W04NU

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

1. Padd with 0x00 the .uImage kernel to reach 1,441,792 bytes (dd bs=1408k conv=sync)
dd bs=1408k conv=sync if=../dist/openwrt_r14959_manyUSB1-ar71xx-uImage-gzip.bin of=openwrt_r14959_manyUSB1-ar71xx-uImage-gzip.bin.padded
2. Padd with 0x00 the .squashfs file to reach 6,356,992 bytes (dd bs=6208k conv=sync)
dd bs=6208k conv=sync if=
3. Concatenate the 2 above files (.uImage + .squashfs = .bin). We now have the .bin file
4. Add the Planex header (34 bytes) using (mkplanexfw). We now have the .webui file

1,441,792 + 6,356,992 + 34 = 7,798,818 bytes. 65,502 bytes were missing in the target/linux/ar71xx/image/Makefile in order the firmware could be uploaded via the Planex http interface :

5. Padd with 0x00 the .webui image to reach 7,864,320 bytes (dd if=.webui bs=7680k sync=conv of=.webui2)

After that, I could upload the firmware successfully.

Note : The last padd must be done AFTER the Planex header writing, if done before, the header won't be accepted by Planex GUI.

For example: mtd -r write openwrt-ar71xx-mzk-w04nu-squashfs.bin firmware

BTW, planex flashes with 7798818 bytes .webui without any problem in my case.

The .uni file format can be flashed from the original vendor firmware webpages or from within OpenWrt using the mtd command.
