Warning: This page is designed to be used with a 'release' URL parameter.
This page is using the default release RELEASE_BUSTER_V3.1_DART-MX8M.
To view this page for a specific Variscite SoM and software release, please follow these steps:
- Visit variwiki.com
- Select your SoM
- Select the software release
Build U-Boot from source code
Toolchain installation for out of builds
To install the toolchain, follow the Debian Toolchain installation guide.
Build U-Boot out of tree
Obtain sources:
$ git clone https://github.com/varigit/uboot-imx.git -b imx_v2019.04_4.19.35_1.1.0-var01 $ cd uboot-imx
Configure compilation environment:
$ export ARCH=arm64 $ export CROSS_COMPILE=~/debian_imx8mq-var-dart/toolchain/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
Cleanup everything:
$ make mrproper
Select configuration:
$ make imx8m_var_dart_defconfig
Build U-Boot:
$ make -j$(nproc)
Build boot image
The final boot image contains multiple firmware files, as explained by NXP in IMX_LINUX_USERS_GUIDE.pdf (Search for "How to build imx-boot image by using imx-mkimage").
The following procedure builds the final image:
Create imx-boot-tools directory:
$ mkdir imx-boot-tools $ cd imx-boot-tools
Download DDR and HDMI/DP firmware:
$ git clone https://github.com/varigit/debian-var.git -b debian_buster_var02 $ cp debian-var/variscite/imx8m-var-dart/imx-boot-tools/*ddr4* . $ cp debian-var/variscite/imx8m-var-dart/imx-boot-tools/signed_* .
Download ATF:
$ git clone https://github.com/nxp-imx/imx-atf -b imx_4.19.35_1.1.0 $ cd imx-atf $ git apply ../debian-var/variscite/imx8mq-var-dart/imx-boot-tools/imx-atf/* $ unset LDFLAGS $ make PLAT=imx8mq bl31 $ cp build/imx8mq/release/bl31.bin .. $ cd ..
Copy U-Boot binaries:
$ cp ../tools/mkimage mkimage_uboot $ cp ../u-boot.bin . $ cp ../u-boot-nodtb.bin ../spl/u-boot-spl.bin ../arch/arm/dts/fsl-imx8mq-var-dart.dtb .
Download imx-mkimage:
$ git clone https://github.com/nxp-imx/imx-mkimage -b imx_4.19.35_1.1.0 $ cp debian-var/variscite/imx8m-var-dart/imx-boot-tools/imx8m-var-dart/soc.mak . $ cp imx-mkimage/iMX8M/*.c imx-mkimage/iMX8M/*.sh .
Build boot image:
$ make -f soc.mak clean $ make -f soc.mak SOC=iMX8MQ dtbs=fsl-imx8mq-var-dart.dtb MKIMG=./mkimage_imx8 PAD_IMAGE=./pad_image.sh CC=gcc OUTIMG=imx-boot-sd.bin flash_evk
Install the built U-Boot on an SD card
$ sudo dd if=imx-boot-sd.bin of=/dev/sdX bs=1K seek=33 conv=fsync (Replace /dev/sdX with the correct device)
If you want to use our recovery SD card to flash the built U-Boot to NAND flash/eMMC, then copy it to the appropriate location in the SD card:
$ sudo cp imx-boot-sd.bin /media/rootfs/opt/images/Debian
And eject the SD card gracefully from host machine.
Note: If you manually upgrade an existing U-Boot, and you have an old environment saved, it is a good idea to reset your environment to the new default (see Environment handling commands)
Update your U-Boot out of Debian tree
$ cd uboot-imx $ git pull
