Updating image u boot internet dating name ideas
This mostly makes sense during U-Boot or Linux development.We provide Open Embedded recipes which build U-Boot and Linux as part of a complete image, hence if you plan to build a complete image follow the Open Embedded (core) article.Note: If the module fails to boot Linux after updating U-Boot, consider resetting the U-Boot environment.To reset the environment to the updated default environment, enter the following from the command line of the updated U-Boot: U-Boot allows to run standalone applications which may use callbacks into the U-Boot binary.U-Boot 2016.01 (Apr 30 2016 - 0900) DRAM: 896 Mi B HW Revision: 1 MMC: NEXELL DWMMC: 0, NEXELL DWMMC: 1 In: serial Out: serial Err: serial Net: eth0: [email protected] Hit any key to stop autoboot: 0 ARTIK5# The U-Boot environment is a block of memory that is kept in persistent storage and copied to RAM when U-Boot starts.It is used to store environment variables, which can be used to configure the system. Note: Editing U-Boot environment variables can affect boot controls, so do not edit them without knowledge of the system.Linaro releases well tested binary toolchains which can be used to cross compile software for our modules (choose gcc-linaro-6.2.1-2016.11-x86_64_xz): https://releases.linaro.org/components/toolchain/binaries/6.2-2016.11/arm-linux-gnueabihf/ Beginning with image V2.6, as part of our Open Embedded Jethro update we transitioned to using version 5.2 of the gcc compiler.Linaro releases well tested binary toolchains which can be used to cross compile software for our modules (choose gcc-linaro-5.2-2015.11-2-x86_64_xz): https://releases.linaro.org/components/toolchain/binaries/5.2-2015.11-2/arm-linux-gnueabihf/ Beginning with image V2.0, we transitioned to using the hard-float ABI: https://releases.linaro.org/archive/14.11/components/toolchain/binaries/ Note: Since the 14.11 release Linaro only provides x86_64 toolchains.
The SPL gets loaded by the bootrom into the So C's SRAM, executes and initializes the DDR RAM according to module type, then it loads U-Boot to DDR and executes it.
This article also includes download and build of the software described further down.
The source code of the U-Boot boot loader and the Linux kernel may be found on our Git server at git.
Note: Refer to the Txx Recovery Mode article if the module is not able to boot into U-Boot.
After the update, reset or power cycle to execute the new U-Boot.
