Only 32MB of RAM, still works for simple tasks

First time i couldn't update via image in /tmp. Whatever i've tried memory was too low. So, USB storage might be needed from now on to update.

If you're on 23.05.4 without USB support you need some files from here:

kmod-fs-exfat_5.15.162-1_mips_24kc.ipk
kmod-scsi-core_5.15.162-1_mips_24kc.ipk
kmod-scsi-generic_5.15.162-1_mips_24kc.ipk
kmod-usb-storage_5.15.162-1_mips_24kc.ipk

This is for exfat only. Add/replace other formats if needed.

Same as script (change ssh ip beforehand):

#!/bin/bash

wget https://downloads.openwrt.org/releases/23.05.4/targets/ath79/generic/kmods/5.15.162-1-da89f936189e8280762513898b74a850/kmod-fs-exfat_5.15.162-1_mips_24kc.ipk \

 https://downloads.openwrt.org/releases/23.05.4/targets/ath79/generic/kmods/5.15.162-1-da89f936189e8280762513898b74a850/kmod-scsi-generic_5.15.162-1_mips_24kc.ipk \
 https://downloads.openwrt.org/releases/23.05.4/targets/ath79/generic/kmods/5.15.162-1-da89f936189e8280762513898b74a850/kmod-usb-storage_5.15.162-1_mips_24kc.ipk

for i in *.ipk; do 
	tar xf "$i"
	tar xf data.tar.gz 
done

tar czf - lib |ssh root@192.168.1.2 -- "tar xzf - -C /tmp"

Then find the files in /tmp/lib/modules and insert them manually with 'insmod'. Order might be important. Just try until it works. Then insert USB stick and check with dmesg |tail if it got registered as /dev/sda.


Imagebuilder-23.05.5:

  • USB support added (exfat only, add more formats manually)
  • Insert 'files' folder after image extraction from here for low-memory tweaks
