I have installed OpenWRT following the "Installation with U-Boot 2019.07 or later" guide here https://openwrt.org/toh/turris/turris_omnia.
With the OEM install the root partition uses the 8GB of the MMC. With the OpenWRT install the root partition is only using 100MB of an overlayfs. See screenshot below.
How can I get OpenWRT to use the 8GB of the MMC? Thanks.
It is only my assumption, that you should download ImageBuilder, change configuration, and build firmware yourself.
I see, the .gz archive is rather strange:
gzip: openwrt-21.02.3-mvebu-cortexa9-cznic_turris-omnia-sysupgrade.img.gz: decompression OK, trailing garbage ignored
@ulmwind thanks - I attempted the imagebuilder, and it has same partition layout with the small sized overlay.
Any other ideas out there?
Set the parameter
CONFIG_TARGET_ROOTFS_PARTSIZE. It is used on top level in [openwrt/openwrt.git] / include / image.mk, so I think, it is generated in menuconfig.

This worked! Thanks @ulmwind.
