Iomega iconnect lost settings and programs

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:

I have download following files from openwrt to the tftp server:

My env variables from u-boot:

iconnect => printenv
bootargs_root=root=/dev/mtdblock2 rootfstype=jffs2
bootcmd=run load_openwrt
console=console=ttyS0,115200 panic=20
download_kernel=mw $(loadaddr) 0xffff 0x300000; tftp $(loadaddr) $(kernel_name);
download_rootfs=mw $(loadaddr) 0xffff 0x200000; tftp $(loadaddr) $(rootfs_name);
flash_kernel=nand erase 0x100000 0x400000; nand write.e $(loadaddr) 0x100000 0x400000;
flash_rootfs=nand erase 0x500000 0xfb00000; nand write.e $(loadaddr) 0x500000 0x200000;
load_openwrt=setenv bootargs $(console) $(bootargs_root); nand read $(loadaddr) 0x100000 0x400000; bootm $(loadaddr)

Environment size: 1076/131068 bytes

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.

serial output:

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

i have download the imagebuilder to compile uImage and rootfs from

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

setenv bootargs_root 'root=/dev/mtdblock2 rw rootfstype=jffs2' or setenv bootargs_root 'root=/dev/mtd2 rw rootfstype=jffs2' didn't work

I think that everything fail in the Kernel to use the mtd Partition (diver?), but what

What i must do to boot openwrt?
