| Verdin iMX8M Plus Module |
| ======================== |
| |
| Quick Start |
| ----------- |
| |
| - Build the ARM trusted firmware binary |
| - Get the DDR firmware |
| - Build U-Boot |
| - Flash to eMMC |
| - Boot |
| |
| Get and Build the ARM Trusted Firmware (Trusted Firmware A) |
| ----------------------------------------------------------- |
| |
| .. code-block:: bash |
| |
| $ echo "Downloading and building TF-A..." |
| $ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git |
| $ cd trusted-firmware-a |
| |
| Then build ATF (TF-A): |
| |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-linux-gnu- |
| $ make PLAT=imx8mp IMX_BOOT_UART_BASE=0x30880000 bl31 |
| $ cp build/imx8mp/release/bl31.bin ../ |
| |
| Get the DDR Firmware |
| -------------------- |
| |
| .. code-block:: bash |
| |
| $ cd .. |
| $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.1.bin |
| $ chmod +x firmware-imx-8.10.1.bin |
| $ ./firmware-imx-8.10.1.bin |
| $ cp firmware-imx-8.10.1/firmware/ddr/synopsys/lpddr4*_202006.bin ./ |
| |
| Build U-Boot |
| ------------ |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-linux-gnu- |
| $ make verdin-imx8mp_defconfig |
| $ make |
| |
| Flash to eMMC |
| ------------- |
| |
| .. code-block:: bash |
| |
| > tftpboot ${loadaddr} flash.bin |
| > setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200 |
| > mmc dev 2 1 && mmc write ${loadaddr} 0x0 ${blkcnt} |
| |
| As a convenience, instead of the last two commands one may also use the update |
| U-Boot wrapper: |
| |
| .. code-block:: bash |
| |
| > run update_uboot |
| |
| Boot |
| ---- |
| |
| ATF, U-Boot proper and u-boot.dtb images are packed into FIT image, |
| which is loaded and parsed by SPL. |
| |
| Boot sequence is: |
| |
| * SPL ---> ATF (TF-A) ---> U-Boot proper |
| |
| Output: |
| |
| .. code-block:: bash |
