U-Boot for the Technexion Pico i.MX8MQ
|
|
|
|
Quick Start
|
|
===========
|
|
- Build the TFA binary
|
|
- Get DDR and HDMI firmware
|
|
- Build U-Boot
|
|
- Boot
|
|
|
|
Get and Build the TFA blob
|
|
==========================
|
|
Note: srctree is U-Boot source directory
|
|
Get ATF from: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
|
|
branch: master
|
|
$ CROSS_COMPILE=aarch64-linux-gnu- make PLAT=imx8mq bl31
|
|
$ cp build/imx8mq/release/bl31.bin $(builddir)
|
|
|
|
Get the DDR and HDMI firmware
|
|
=============================
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.9.bin
|
|
$ chmod +x firmware-imx-7.9.bin
|
|
$ ./firmware-imx-7.9.bin
|
|
# Or use this to avoid running random scripts from the internet,
|
|
# but note that you must agree to the license the script displays:
|
|
# $ dd if=firmware-imx-7.9.bin of=firmware-imx-7.9.tar.bz2 bs=38868 skip=1
|
|
# $ tar -xf firmware-imx-7.9.tar.bz2
|
|
$ cp firmware-imx-7.9/firmware/hdmi/cadence/signed_hdmi_imx8m.bin $(builddir)
|
|
$ cp firmware-imx-7.9/firmware/ddr/synopsys/lpddr4*.bin $(builddir)
|
|
|
|
Build U-Boot
|
|
============
|
|
$ export CROSS_COMPILE=aarch64-poky-linux-
|
|
$ make pico-imx8mq_defconfig
|
|
$ make flash.bin
|
|
|
|
Burn the flash.bin to MicroSD card offset 33KB
|
|
$ dd if=flash.bin of=/dev/mmcblkX bs=1024 seek=33
|
|
Or into eMMC from a running system
|
|
$ dhcp flash.bin && mmc write $loadaddr 0x42 0x800
|
|
|
|
