Hi,
First time poster but long time user here.
I've installed the latest available snapshot to TP-Link RE450 v2 but the available disk space under /overlay is way smaller (608kB) than on the stable 19.07.7 version (1.5M).
The goal would be to install LUCI on it.
Disk usage on 19.07.7:
Edit2: I am aware of the 8/64 recommendation. My intention is to use this device as an bridged AP with different VLANs/SSIDs (no dnsmasq, no firewall and no other whistles). It would be still nice to have LUCI on it. Yeah, this might be already a whistle
0x5e0000 = 6'160'384 bytes, which is around the size needed for a current firmware image with WPA3/ SSL and luci. 8 MB flash isn't a whole lot to begin with, but with rather wasteful flash partitioning by the vendor, this quickly gets too tight.
Thanks for your reply. Just realized that snapshots do not contain luci by design, but releases like 21.02-rc1 do.
I could install luci-ssl and still have some space left.
I think one problem lies in the unused address range from 0x5e0000 to 0x60000 and essentially 0x65000 to 0x7f0000. Is there any way that this can be made usable?
I had a look in the original TP-Link .bin-File. The current flash layout seems to be just copied from the original which also lacks the same area after 0x650000. I'm unfamiliar with creating OpenWRT images, but is there any way for a sysupgrade image to keep the data at 0x600000 and put the rootfs_data after 0x650000? Is it even safe to use that space und is there any 'hidden' data in the flash? It would be ideal if both areas, the 576kb plus 1,6MB could be joined.
Does not look like this issue can or will be resolved. I was able to use 19.X sysupgrade images, but with 21.X to create a dumb AP I have to use the custom image builder - with few packages stripped and ssl hostapd added I have about 500K of overlay space left ( with a full luci interface ).
