Installation
1. Follow the steps on Installation_guide#Initialization
2. Choose the radxa-zero
device
3. Start the build process and install the completed image to a sdcard
$ pmbootstrap install --sdcard /dev/sdX
(replace /dev/sdX with the device for your sdcard or the emmc of it)
4. If you install pm os on sdcard , then Place the sdcard into the Radxa Zero and boot it. If not unplug the usb cable.
Boot process
If emmc is bootable :
bootrom ==> emmc ==> uboot ==> postmarketOS
Else if sdcard is bootable :
bootrom ==> emmc ==> uboot ==> postmarketOS
Else :
bootrom ==> flashmode
Wifi
Depend on your Radxa Zero, it might be had one of those Wi-Fi modules : AW-CM256SM(some of the Radxa Zero v1.5 had this),AP6256(Radxa Zero 2/4/8GB had this),AP6212(Radxa Zero 1024/512MB had this) so the wifi of your Radxa Zero might not work due to the wifi modules on your Radxa Zero isnt supported by the kernel or the firmware that is in the pm os.
As of now , the only Wi-Fi modules that seem to supported by the kernel and the firmware is AP6256.
