`fastboot oem format` command from client: You can start by formatting the internal storage by executing the These partitions have also assigned GUID's according to Discoverable Partitions Specification, to enable automatic discovery of partitions and their mountpoints. esp - EFI system partition (VFAT), for u-boot scripts (boot.scr).loader2 - partition for u-boot (not needed for SPI-based bootloader).loader1 - partition for SPL - secondary program loader (not needed for SPI-based bootloader).Now that the device is in the fastboot mode, we can continue withĬreating the partitions on the device. To overcome this, some manufacturers are also populating the board with SPI EEPROM for storing the SPL and u-boot, so you do not have to populate loader1/loader2 partitions. On some older devices booting directly from eMMC might fail due to BROM not supporting newer eMMC variants. And for fun, you can alsoįetch the bootloader version using the fastboot protocol:īootloader-version: U-Boot 2018.13-ge3beca3a2f On the client machine, you can check whether the device is visible To enter into fastboot mode, execute the `fastboot` command in Sunxi device connected to client via OTG port.EFI partition (VFAT) for u-boot scripts.root file system containing operating system.u-boot binaries for the target sunxi device.sunxi-tools installed on client machine (optional).fastboot binaries installed on client machine.This document currently walks through an installation with a device The device is started in a boot loader or Secondary Boot Loader mode. 1.2 Getting your device into Fastboot modeįastboot is a diagnostic protocol, primarily used to modify theįilesystems on the flash device via USB or UDP.
