side topic: my Intel AX201 connects with reduced network capabilities as it connects using 802.11n as opposed to ax. Other devices connect just fine. I've already installed the latest Intel driver. Does anyone observe the same issue?
Can you send me your BDFs for the MX5500 and I’ll give them a try?
no the structure has never changed. only the regdb which is attached at the end might change. everying else is just extended by previous reserved fields. if you have access to the bdf text files you can compare it between multiple versions of the qca-networking source. i did this already. generally the file consists of mulitple segments. there is a ID number followed by the length of thesegment. so you can split these files into the categories

The IPQ5018 BDF file for MX5500 is based on WiFi firmware version 2.4 and is version 1.1.2.
Since that version, the BDF file format has changed:
2.0.0- regdb resized (7k->10k), added new segment 283.0.0- added new segment 183.1.0- segment 28 resized (131->132), segment 29 resized (12.6k->22.6k)

as i said. all bdf's i'm using are part of the 12.5 firmwares i provided. the rest you can to with ath11k swiss army knife tool. unlike openwrt i have a single board-2.bin file which contains all models. i modified them on my side
Hello georgem83.
Please clarify where to download a recent factory image for MX2000?
I see nothing for IPQ5018 at https://downloads.openwrt.org/releases/23.05.5/targets/.
Instructions to compile factory image from source code would be also great.
updated the latest images for MX2000:
Please report back any issues and whether it works for you
now we're getting somewhere, think I'm happy with the updated BDFs for MX2000:
also, maxing out my ISP's connection, so things look good. Will update the repo and avail new images shortly.
likewise for QCN9074, regdb section resized to 10kb, shifting all following sections out by 3,072 bytes. Found out while I was converting the MX5500 BDF from an ancient version to the latest..
fresh images for MX5500 with updated stock / device-specific BDFs:
would appreciate feedback and report on any issue you may encounter
These files didn't work for me, just bricked my MX55EC, it never assigned a DHCP IP to my computer.
Restarted the router two times to revert back to OpenWrt SNAPSHOT r27596-7ef8ce27c6 / LuCI Master 24.264.56398~8449716
Do you have any logs?
No logs, I was doing OTA firmware update. I don't the router cracked open to attach a serial cable to it.
I can try later today with my other MX55EC.

sysupgrade is not working yet. You'd have to flash the factory image. I would recommend you create a backup first to save your settings and then restore them after you install the updated factory image.
see flash instructions:
new images uploaded for MX2000 & MX5500:
sysupgrade seems to have worked for me on both devices (with a caveat). Will post the logs below
Here are the logs of the sysupgrade process. 2 things caught my attention:
- kernel panic when trying to remove the ubi device
- 'resource busy' when unmounting /dev/ and /tmp/ after config is saved
Both don't seem to have impacted the upgrade process though:

I don't think there's anything special in the logs. The problem was noticed earlier: https://github.com/openwrt/openwrt/pull/14844#issuecomment-1998680617
It seems need to add "swiotlb=1" to bootargs-append, otherwise Linux 6.6 will pre-allocate 64M of memory, causing a memory drop. Adding this will only allocate 1M of memory (from 450 to 460m available to 500 to 510m available)
"swiotlb=1" I found it from qsdk ipq6018'dts, I don't know if there is a better value.
At the same time, Linux 6.6 also adds a CONFIG_SWIOTLB_DYNAMIC, which seems to be able to dynamically allocate swiotlb.
I tested on ax9000 and there is no problem with this configuration.
I use "swiotlb=1" in my bootargs and I have not seen this sysupgrade error in any of my attempts. However, I have not successfully sysupgraded yet, so perhaps I am just not getting to the point of the panic
