U-Boot for the Gateworks i.MX8M Mini Venice Development Kit boards Quick Start =========== - Build the ARM Trusted firmware binary - Get ddr firmware - Build U-Boot - Flash to eMMC - Boot Get and Build the ARM Trusted firmware ====================================== $ git clone https://source.codeaurora.org/external/imx/imx-atf $ git checkout imx_5.4.47_2.2.0 $ make PLAT=imx8mm CROSS_COMPILE=aarch64-linux-gnu- bl31 $ cp build/imx8mm/release/bl31.bin . Get the DDR Firmware ==================== $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin $ chmod +x firmware-imx-8.9.bin $ ./firmware-imx-8.9.bin $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin . Build U-Boot ============ $ make imx8mm_venice_defconfig $ make CROSS_COMPILE=aarch64-linux-gnu- Update eMMC =========== => tftpboot $loadaddr flash.bin => setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200 => mmc dev 2 && mmc write $loadaddr 0x42 $blkcnt # for IMX8MM => mmc dev 2 && mmc write $loadaddr 0x40 $blkcnt # for IMX8MN
