Page 5: Introduction
Beyond the OS each platform needs its corresponding bootloader like RedBoot, U-Boot or Flash-N-Go-Boot. Usually the sources of the bootloaders are not provided by the Garz & Fricke BSPs. The bootloader is responsible for loading the kernel of the desired operating system into memory and provide the kernel with information it needs to work correctly.
Page 6: Overview
Newer Garz & Fricke devices are shipped with a separate small ramdisk-based Linux system called Flash-N-Go System which is installed in parallel to the main operating system. The purpose of Flash-N-Go is to provide the user a comfortable and secure update mechanism for the main operating system components. 2.1 The bootloader There are several bootloaders available for the various Linux and Windows platforms.

Page 8: Flash-N-Go Boot
Flash-N-Go User Manual 15.1-r8673 3 Flash-N-Go Boot Flash-N-Go Boot is a simple, non-interactive bootloader. It will be started by the SoC-Boot-ROM from MMC/SD- Card storage media (usually the internal eMMC of the system), runs completely from SoC-internal SRAM, initial- izes the system clocks and DRAM, loads ﬁles from its boot-medium into any place in RAM and is able to execute certain kinds of binary images.
Page 9: Devtree Command
Flash-N-Go User Manual 15.1-r8673 3.1.3 Devtree Command (Only available starting with v5.0r3274 an newer) Flash-N-Go Boot devtree -b <pfid>:<socid>:<address> [-p <partition name>] <filename> This command works similar to the load-command but is intended to load so-called "device trees" for newer Linux kernels, only, therefore no -r-parameter is supported and as newer Linux kernels require a proper device-tree, ﬁles loaded by this command cannot be speciﬁed as optional.
Page 10: Testram Command
Flash-N-Go User Manual 15.1-r8673 If a load-command has been executed before to load an executable binary image ﬁle that Flash-N-Go Boot knows about, e.g. a Linux kernel using U-Boot kernel Image format or Android Boot-Image format, the -b- parameter is optional. In all other cases the -b-parameter is mandatory and will be the address in memory Flash-N-Go Boot will jump to.
