Having previously written the file system of any OS to one of its partitions. Connect an external drive via the USB connector. "u-boot" reads the file armbianEnv.txtįor verification, you can boot from the SD card. This process can be seen in the UART console. This is done using the "sunxi-tools" utility.ġ-2) When the boot code "u-boot" is found on one of these media, it starts working and scans the devices for downloading about which it has information. In this mode, you have the opportunity to read or write any boot code to a soldered memory chip. In devices with allwinner chips, a simple code is hard-wired that polls possible boot devices in the following order:ģ) if they are empty, the device switches to "fel" mode and becomes available when it is connected to another computer using a USB cable.
