Installing and Using OpenWrt

Hello all,
I'm trying Cudy wr3000s router and everything works great but the disk space that appear in status page only show 44.68MiB.

Also, flash layout shows this size

root@MiCasaRT:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 "BL2"
mtd1: 00080000 00020000 "u-boot-env"
mtd2: 00200000 00020000 "Factory"
mtd3: 00040000 00020000 "bdinfo"
mtd4: 00200000 00020000 "FIP"
mtd5: 04000000 00020000 "ubi"

Since this router has a 128MiB flash, what can I do to get the full flash memory available? Is it a openWRT bug or a hardware limitation?

Thanks in advance,

Stock partitioning limit, it would require a ubootmod PR to get maximal flash space.

Thank you for your response.
Sorry for my ignorance but, how can I do it? Perhaps open a issue in Github first?

by submitting the config change required.

there's no issue, it's a layout change PR someone (you ?) have to provide.

similar to the one submitted for the TR3000 - https://github.com/openwrt/openwrt/pull/18945.

There is no issue. OpenWrt partitions fit the design of Cudy, in order to be bootable, and to restore Cudy firmware if needeed. Changing the layout is a heavy procedure, it involves deep changes, and after that you can't (simply) restore Cudy firmware. Hence you MUST know what you do before proceeding. So unless you have deep knowledge in partitioning your device ... just stick to what it is now :wink:

... or swap to a device where ubootmod is already available.

Ok. Thanks for your responses. Since my lack of knowledge to do this, I will look for another device.
