- 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
- Boot
