| 9 | Quick Start |
| 10 | ----------- |
| 11 | |
| 12 | - Build the ARM trusted firmware binary |
| 13 | - Get the DDR firmware |
| 14 | - Build U-Boot |
| 15 | - Flash to eMMC |
| 16 | - Boot |
| 17 | |
| 18 | Get and Build the ARM Trusted Firmware (Trusted Firmware A) |
| 19 | ----------------------------------------------------------- |
| 20 | |
| 21 | .. code-block:: bash |
| 22 | |
| 23 | $ echo "Downloading and building TF-A..." |
| 24 | $ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git |
| 25 | $ cd trusted-firmware-a |
| 26 | |
| 27 | Then build ATF (TF-A): |
| 28 | |
| 29 | .. code-block:: bash |
| 30 | |
| 31 | $ export CROSS_COMPILE=aarch64-linux-gnu- |
| 32 | $ make PLAT=imx8mp IMX_BOOT_UART_BASE=0x30a60000 bl31 |
| 33 | $ cp build/imx8mp/release/bl31.bin ../ |
| 34 | |
| 35 | Get the DDR Firmware |
| 36 | -------------------- |
| 37 | |
| 38 | .. code-block:: bash |
| 39 | |
| 40 | $ cd .. |
| 41 | $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.1.bin |
| 42 | $ chmod +x firmware-imx-8.10.1.bin |
| 43 | $ ./firmware-imx-8.10.1.bin |
| 44 | $ cp firmware-imx-8.10.1/firmware/ddr/synopsys/lpddr4*_202006.bin ./ |
| 45 | |
| 46 | Build U-Boot |
| 47 | ------------ |
| 48 | |
| 49 | .. code-block:: bash |
| 50 | |
| 51 | $ export CROSS_COMPILE=aarch64-linux-gnu- |
| 52 | $ make toradex-smarc-imx8mp_defconfig |
| 53 | $ make |
| 54 | |
| 55 | Flash to eMMC |
| 56 | ------------- |
| 57 | |
| 58 | .. code-block:: bash |
| 59 | |
| 60 | > tftpboot ${loadaddr} flash.bin |
| 61 | > setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200 |
| 62 | > mmc dev 0 1 && mmc write ${loadaddr} 0x0 ${blkcnt} |
| 63 | |
| 64 | As a convenience, instead of the last two commands, one may also use the update |
| 65 | U-Boot wrapper: |
| 66 | |
| 67 | .. code-block:: bash |
| 68 | |
| 69 | > run update_uboot |
| 70 | |
| 71 | Boot |
| 72 | ---- |
| 73 | |
| 74 | ATF, U-Boot proper and u-boot.dtb images are packed into a FIT image, |
| 75 | which is loaded and parsed by SPL. |
| 76 | |
| 77 | Boot sequence is: |
| 78 | |
| 79 | * SPL ---> ATF (TF-A) ---> U-Boot proper |
| 80 | |
| 81 | Output:: |
| 82 | |
| 83 | U-Boot SPL 2025.04-rc5-00023-g34c31be81211 (Apr 04 2025 - 15:36:23 +0100) |
