| 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://github.com/nxp-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 |
