WAX206 overlay mount point too small

Installing and Using OpenWrt
1

Hi,
On WAX206 openwrt relase 24.10.0 (default installation) mountpoint overlay size is only 17.5 MB
Filesystem Size Used Available Use% Mounted on
/dev/root 4.8M 4.8M 0 100% /rom
tmpfs 244.4M 2.5M 241.9M 1% /tmp
/dev/ubi0_1 17.5M 11.2M 5.4M 68% /overlay
overlayfs:/overlay 17.5M 11.2M 5.4M 68% /
tmpfs 512.0K 0 512.0K 0% /dev

This device is equipped with Flash 256 MiB
Comparing with my older Netgear R7800 with 128 Mib Flash only overlay partition looks much bigger:
Filesystem Size Used Available Use% Mounted on
/dev/root 4.3M 4.3M 0 100% /rom
tmpfs 231.5M 2.1M 229.4M 1% /tmp
/dev/ubi0_1 77.8M 9.2M 64.6M 13% /overlay
overlayfs:/overlay 77.8M 9.2M 64.6M 13% /
tmpfs 512.0K 0 512.0K 0% /dev

So, is it possible to resize overlay on WAX206 to use max of available space ?

Yes, if you create your own image with the new layout.

Keep in mind the 206 is a dual flash device.

Hi,
Thx for Your advice. I have no experience in creating custom image,
but after creating my own image using "Customize installed packages" wizard on firmware download page, my problem has been solved.
I have added all my packages that I needed to the customized image.
Overlay size is smaller than before but used space is only 1%
/dev/ubi0_1 12.2M 76.0K 11.5M 1% /overlay

Modify the DTS memory distribution of wax206 to use all the space, refer to this https://github.com/small-white-rabbit/openwrt-wax206Exp/blob/main/target/linux/mediatek/dts/mt7622-netgear-wax206.dts ，
Of course, you can also compile it yourself based on this, but it is best to flash the img base package in this link before flashing the bin upgrade package
