Hello,
i have installed U-Boot, uImage and squasfs_factory files to the nand of the device.
The device starts openwrt Version OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a.
If i create a root password and install some packages with opkg, after a reboot the root password and the installed packages are lost and i most reconfigure the system.
What i most do that the settings and installed programms didnt lost after a reboot?
Sounds like your device is out of storage space and cannot save any changes.
Create a smaller image using imagebuilder and flash that instead. Remove anything you don’t need.
Looking at the device page you should have 32mb available to openwrt. That’s enough for a basic system.
How much free storage does Luci report? Or df -h in the command line?
Which install instructions did you follow? This device has a fairly non-standard install process and mtd partition scheme
I use follow tutorial to install openwrt to iomega iconnect:
https://openwrt.org/toh/iomega/iconnect
I have download following files from openwrt to the tftp server:

I have flashed the new u-boot with section 4.2, but i use the file u-boot.kwb.
Then i have write uimage and openwrt section 6.2:
Only env variables kernel_name and rootfs_name i have changed:
setenv kernel_name 'openwrt-21.02.3-kirkwood-iom_iconnect-1.1-initramfs-uImage'
setenv rootfs_name 'openwrt-21.02.3-kirkwood-iom_iconnect-1.1-squashfs-sysupgrade.trx'
after reboot openwrt boots, but if i change root password or install programs after a reboot nothing was saved.

Ok, you’re running from an initramfs image. These boot from ram only and do not allowing settings to be persistent.
Do a sysupgrade from the initramfs image and then change your uboot bootcmd to boot from the rootfs partition and it ‘should’ boot.
The instructions call for a standalone kernel image
Hello,
i have download the imagebuilder to compile uImage and rootfs from https://downloads.openwrt.org/releases/21.02.3/targets/kirkwood/generic/openwrt-imagebuilder-21.02.3-kirkwood.Linux-x86_64.tar.xz
iom_iconnect-1.1-uImage and openwrt-21.02.3-kirkwood-checkpoint_l-50-squashfs-sysupgrade.bin i have write to the nand, but if i start the iconnect, he didn't find everything

I think that everything fail in the Kernel to use the mtd Partition (diver?), but what
What i must do to boot openwrt?
