Overview

This page is meant to be a starting point for people to learn build a u-boot image and show to people the current status of different u-boot versions for IGEP Processor Boards.

What is U-Boot?

Das U-Boot (Universal Bootloader) is an open source, primary boot loader used in embedded devices. Its primary purpose in the shipping system is to load some operating system.

That means that U-Boot is necessary to perform a certain task, but it's nothing you want to throw any significant resources at. Typically U-Boot is stored in relatively small NOR flash memory, which is expensive compared to the much larger NAND devices often used to store the operating system and the application.


Necessary package

   


Download & Prepare your U-BOOT

 Will be a distintion between NXP-processors products and ARM-processors products.

Commercial Name U-Boot Series
IGEPv2 DM3730 ARM
IGEP COM MODULE DM3730/AM3703 ARM
IGEP COM AQUILA AM335x ARM 
IGEPv5 OMAP5432 ARM
IGEP SMARC AM335x ARM
IGEP SMARC AM335x Lite ARM
IGEP SMARC iMX6 Solo Freescale-NXP
IGEP SMARC iMX6 Dual Lite Freescale-NXP
IGEP SMARC iMX6 Dual Freescale-NXP
IGEP SMARC iMX6 Quad Freescale-NXP


U-Boot ARM Serie

First we will download the U-Boot file for be able to make the configuration.

Downloading binary files

Clone the u-boot repo

Clone the u-boot repository using git address:

$ git@git.isee.biz:arm-boot/u-boot-arm.git 

or

 $ git clone https://git.isee.biz/arm-boot/u-boot-arm.git

Checkout u-boot repo 

Go to the u-boot-arm directory and checkout the isee_v2017.03 as:

$ cd u-boot-arm

$ git checkout remotes/origin/isee_v2017.03 -b isee_v2017.03 

U-Boot Freescale-NXP  Serie

First we will download the U-Boot file for be able to make the configuration.

Downloading binary files

Clone the u-boot repo

Clone the u-boot repository using git address:

$ git clone git@git.isee.biz:arm-boot/u-boot-imx.git

or

 $ git clone https://git.isee.biz/arm-boot/u-boot-imx.git

Checkout u-boot repo 

Go to the u-boot-imx directory and checkout the version 2015.04.y as:

$ cd u-boot-imx

$ git checkout remotes/origin/isee_imx_v2017.03_4.9.11_1.0.0_ga -b isee_imx_v2017.03_4.9.11_1.0.0_ga 

Once we have downloaded we will execute the file called defconfig, that it variates in function of each model.


Set the board configuration(Prepare your U-BOOT)

Model defconfig Example
IGEPv2 DM3730 igep0020_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- igep0020_defconfig
IGEP COM Module DM3730/AM3703 igep0030_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- igep0030_defconfig 
IGEP COM AQUILA AM335x am335x_igep0033_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_igep0033_defconfig
IGEPv5 OMAP5432  
----
IGEP SMARC AM335x  am335x_igep0034_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_igep0034_defconfig
IGEP0046 SMARC Solo  
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- xxxxx 
IGEP0046 SMARC Dual lite igep0046_imx6dl_2G_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- igep0046_imx6dl_2G_defconfig 
 IGEP0046 SMARC Dual     
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- xxxxx 
 IGEP0046 SMARC Quad igep0046_imx6q_2G_defconfig
 $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- igep0046_imx6q_2G_defconfig


Build u-boot

 Once we execute the defconfig. You can build u-boot executing this command:

 $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-


  • The result for Texas Instruments processor based board will be a MLO and u-boot.img.
  • The result for iMX6 processor based will be a u-boot.imx.


You can install these files, for example, in the boot partition of a SD-card.  

What next...

After build u-boot you can use it for boot the board, exist several options for boot, check the Hardware Reference Manual about the options available for your board.
