Clone of OpenWrt repo with required changes and installable binaries. v24.10.0 (I'll add other releases as they become available, and patches can be adjusted for Snapshot but that's a moving target I don't want to keep up with):
Changes for device support are in a single commit. A second commit has the fan control daemon. Will merge those for future releases.
GitHub releases include flashable binaries, but building your own is straightforward (clone openwrt's repo, check out v24.10.0 and cherry-pick top two releases from here. This repo includes a diffconfig). Images + u-boot are for a D-Link DNS-320-A1. Other hardware versions (including A2) are untested and most probably will not work.
Any feedback or review comments welcome. The goal is to have a PR to add support to OpenWrt main with a non-zero chance for it to be accepted.
Status
Everything works.

Flashing
It is necessary to get dirty to install this. The original u-boot does not support UBI, and a common issue with these devices especially at this age is NAND bad blocks. UBI was therefore a must. If the bootloader was being replaced, so was the old partitioning scheme. Installing this means saying goodbye to stock firmware or Alt-F forever. I'm fine with that.
As scary as flashing the bootloader sounds, these kirkwood devices are unbrickable. Full disassembly, a CP210x USB to UART Bridge (or similar), and a ext2 -formatted USB (or FAT) are required. Most pages on the net about flashing this device consider soldering header pins to the port... I didn't bother and just used a few pieces of a paper clip and masking tape to maintain pressure/contact. That was good enough. That is how easy going these devices are.
(I bought this second hand years ago. Whoever had it before added those heat sinks. Not sure if they help, but they don't come off easily, so I'm letting them be.)
As insurance and nice to have, but not mandatory, it helps to have a working kwboot application, which lets the device to boot from serial. This allows to test a u-boot without flashing it first (that's how friendly and unbrickable it is). Most linux distributions have one, and precompiled versions are available online for Windows.
In best of theories, with kwboot and u-boot plus the uImage it is possible to completely boot from USB without flashing anything. That requires some u-boot environment magic that I couldn't figure out. I already flashed so it's not valuable to me to go back to stock to document that, but it's an option.
Installation steps
These are from memory... will add specifics soon.
- Copy
u-boot.kwbandopenwrt-24.10.0-kirkwood-generic-dlink_dns320-squashfs-factory.binto USB (rename the latter tofactory.binto make life easier. - Connect USB and TTL. Run a terminal on the computer (
minicomworked great for me) - Interrupt the boot by hitting [space] and '1'. Should give a u-boot prompt.
- Load
u-boot.kwbto memory and erate/write it to address 0x0, which is the start of NAND and where the bootloader lives. Unless you make a backup of NAND first, you will have no way back to stock firmware or ALT-F. Do aresetto restart the board with the new u-boot. - Again, interrupt the boot. Load
factory.binto RAM.erase.part ubi(goodbye stock firmware, including mini-firmware, whatever you were) and write to address 0x100000 - add the MAC address of the adapter to the environment with
setenv ethaddr 'FC:75:16:xx:xx:xx'(get it in advance from current firmware or from sticker on bottom) and persist withsaveenv. reset, cross fingers and enjoy the show.
After flash is done further upgrades are handled with sysupgrade or the LuCI UI. Works really well. Already tested ksmbd and netatalk and they both work. snmpd runs fine, and so does collectd. Everything installs via opkg or LuCI. 127MB UBI partition provides tons of free space.
In progress
- it should be possible to avoid disassembly by generating an image that allows flashing the new u-boot and a temporary kernel / root filesystem. Waiting for a small USB-TTL converter so I can permanently install it to the NAS to work on that.
