- requires `KHADAS_OOWOW_BOARD_ID` set in board file (see next commit)
- always produces xz-compressed images, so this automatically disables `COMPRESS_OUTPUTIMAGE`
- uses `xze` script from Khadas, forcing `IN` and `OUT` env vars so it's not confused by fd 1
- to use, add `EXT=image-output-oowow` parameter to build
- to get into oowow:
- VIM3/VIM3L:
- download oowow SD card image from Khadas:
- VIM3: https://dl.khadas.com/products/oowow/system/vim3-oowow-latest-sd.img.gz
- VIM3L: https://dl.khadas.com/products/oowow/system/vim3l-oowow-latest-sd.img.gz
- write image to SD card, use BalenaEtcher or similar
- insert SD card into board (and remove NVMe if present and bootable)
- boot board into Upgrade mode, see https://docs.khadas.com/products/sbc/vim3/install-os/boot-into-upgrade-mode
- oowow should be running now
- recommended: go into Advanced and reset to factory defaults, so MCU, PCIe/USB3 etc is reset to defaults
- VIM4/VIM4N/VIM1S/Edge2: those have oowow in SPI from factory, check out the manual
- there's a few ways to use these images with oowow:
- Using External media
- prepare media (USB), format it with ext4 or fat, copy produced oowow.img.xz to it
- for ease of use, rename the image file, so it begins with the board-id (`vim1s-/vim4-/edge2-` etc)
- boot board into oowow (see oowow's manual)
- insert media into board
- exit wizard, use "Write image to eMMC", browse to "../"
- change from "XXXX only" to "All" if you didn't rename the image
- choose image file and write
- (remove SD card if using one) and reboot
- Via network (Ethernet or Wi-Fi)
- boot board into oowow
- plug in Ethernet cable or connect to Wi-Fi (see oowow's manual)
- set the firewall mode to "allow" in oowow's Network Settings (see oowow's manual)
- obtain the IP address of the board in oowow (usually shown on top of the screen, or see manual)
- from a remote machine, use curl to upload and write the image to oowow's eMMC, example:
- `curl -L <ip_address>/shell/write | sh -s - <image_filename>.oowow.img.xz`
- reboot board
- From the Internet (one day)
- when Khadas publishes Armbian oowow images to their HTTP server
