I have running an tp-link re450 v1 as wlan relay. I´m wondering, there is no sysupgrade image available in firmware selector for build 22.03.0. Do I missed an information about this? My other devices (some Archer c7) got sysupgrade images and running fine with 22.03.0 rc6.
I can't really search the source right now, but I assume 8 MB flash combined with a sub-optimal vendor flash partitioning (the v2 only offers 6 MB usable space, can't find the details for v1 right now) might result in the image no longer fitting.
When I look at the log it says it's missing the sysupgrade file for the RE450 v1. I'm not finding any 'image too big' errors for that device though (you can just filter for the name of the sysupgrade image).
As kind of expected earlier, the maximum firmware size is indeed very limited:
6016 KB…
with the re450-v3 sysupgrade image currently (22.03.0-rc6) weighing 6144.3 KB, it's no wonder why building an image for the re450-v1 doesn't succeed anymore.
Sadly the vendor wastes 1984 KB on 'useless' fluff in their OEM partitioning (partition-table (64 KB), info (128 KB), config (1792 KB)).
