This router has 1GB of NAND, but I can only use about 53MB of storage.
Currently, I’m using a customized OpenWrt build, so after installing some packages, I have only 32MB left. With the official OpenWrt build, the available space is around 53MB as well.
I know I can always use a USB flash drive or other storage devices via the router’s USB port to expand disk space. But my question is:
Why can’t I use the rest of the NAND storage that’s already available on this router?
Nope - it has 1Giga-bit of NAND, ie 128 Mega-Bytes
Please show cat /proc/mtd and ubinfo -a , might be something to do with OEM dual partitioning that you get only a half.
I can see that mtd25: 2cbc0000 00040000 "0:arc_data approximately 716 MB is unused. I can format and mount it in OpenWrt without any problem. Is there a way to make OpenWrt use this partition as rootfs_data?
I tried everything, including using extroot. Even though I was able to mount this as /overlay, I still can't use it for installing packages.Any help is appreciated.
