unzip -p IMAGE.sd.zip '*.img' | sudo dd bs=1M of=/dev/YOUR_SD_CARD

wget http://SERVER/IMAGE.sd.img.gz
gzip -dc IMAGE.sd.img.gz | sudo dd bs=1M of=/dev/YOUR_SD_CARD

wget http://dl.khadas.com/Firmware/VIM1/OpenWrt/IMAGE.sd.img.gz -O- | gzip -dc | sudo dd bs=1M of=/dev/YOUR_SD_CARD

NOTE: Remember to replace the words IMAGE and YOUR_SD_CARD, to the correct values in your system.

Another OS (or if previous methods were difficult for you) / Linux - GUI

Use Balena Etcher to burn the OpenWrt image to your SD card or USB f.

sudo ./balenaEtcher-1.5.57-x64.AppImage

Just select the IMAGE.img.gz or IMAGE.img.zip image, and select your SD card as the target. Press burn! ( There is no need to decompress the image )

BOOT from SD card

  • Best way is to just boot openwrt from your SD card.
  • If your EMMC is empty, openwrt will automatically boot from your SD card.
  • Else, Uboot will start from EMMC by default - it can boot from SD card, but only with the proper version and config!

VIM1 v12 (old) VIM2 v12 old

VIM1 v14 (current) VIM2 v14 (current)

Just triple-press KEY_F (middle button) to force SD bootup!

INSTALL to EMMC (internal storage)

  • Write image to SD card.
  • Open/mount SD card (OW_BOOT partition) on your PC.
  • Activate this script scripts/install2mmc_from_sd.script which is stored in the first partition. Rename it from install2mmc_from_sd.script.disabled -> install2mmc_from_sd.script.
  • Unmount/eject SD card from your PC .
  • Insert SD card into VIM1 (TF card slot).
  • Power on + force boot from SD card by triple pressing KEY_F (middle button).
  • Wait for the "remove SD card" message to appear, before ejecting your SD card.
  • OK! Well done! EMMC boot will occur automatically.

NOTE: All previous EMMC data will be lost!!!
