Updating image u boot

Note: Starting with image V2.7 we use U-Boot together with an SPL to boot from e MMC.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.

You may of course also change any of the other properties as documented in the Toradex Easy Installer article on our developer website.

You may now use above prepared Toradex Easy Installer package with the Toradex Easy Installer.

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.

One has to overcome some obstacles to get the hello_world example in the U-Boot sources up and running on an ARM based CPU.

1) The binary needs to be linked to an address were it eventually gets loaded and executed. set CONFIG_STANDALONE_LOAD_ADDR to your choosen address. 2) U-Boot and the standalone application must be compiled for the same ARM instruction set (arm vs. If you build both binaries from the same configured U-Boot tree that is inherently so.How can I update my u-boot with a serial connection? apalis evaluation board | apalis imx6 | apalis t30 | apalis tk1 | colibri evaluation board | colibri imx6 | colibri imx6ull | colibri imx7 | colibri t20 | colibri t30 | colibri vf50 | colibri vf61 | iris | ixora | orchid This article describes how-to build the U-Boot boot loader and the Linux kernel directly without using a higher level build system such as Open Embedded.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.This article also includes download and build of the software described further down.
