Hello,
I made an custom openwrt image with image builder
make image PROFILE=zbtlink_zbt-we826-16m \
PACKAGES="luci-app-openvpn bash strongswan-full usb-modeswitch kmod-mii kmod-usb-net kmod-usb-wdm kmod-usb-net-qmi-wwan luci-proto-qmi uqmi \
zram-swap uhttpd uhttpd-mod-ubus libiwinfo-lua luci-base luci-app-firewall \
luci-mod-admin-full luci-theme-material " FILES=../../filesystem16/
It builds pretty fine. I work on an 16M device. I lost all my config after reboot, I read the logs seen the following messages.
