| U-Boot for the NXP i.MX8MP EVK board |
| |
| Quick Start |
| ----------- |
| |
| - Build the ARM Trusted firmware binary |
| - Get the firmware-imx package |
| - Build U-Boot |
| - Boot |
| |
| Get and Build the ARM Trusted firmware |
| -------------------------------------- |
| |
| Get ATF from: https://source.codeaurora.org/external/imx/imx-atf |
| branch: imx_5.4.70_2.3.0 |
| |
| .. code-block:: bash |
| |
| $ make PLAT=imx8mp bl31 |
| |
| Get the ddr firmware |
| -------------------- |
| |
| .. code-block:: bash |
| |
| $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.bin |
| $ chmod +x firmware-imx-8.10.bin |
| $ ./firmware-imx-8.10.bin |
| |
| Build U-Boot |
| ------------ |
| |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-poky-linux- |
| $ make O=build imx8mp_evk_defconfig |
| $ cp ../imx-atf/build/imx8mp/release/bl31.bin ./build/bl31.bin |
| $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_202006.bin ./build/ |
| $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_202006.bin ./build/ |
| $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_202006.bin ./build/ |
| $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_202006.bin ./build/ |
| $ export ATF_LOAD_ADDR=0x970000 |
| $ make O=build |
| |
| Burn the flash.bin to the MicroSD card at offset 32KB: |
| |
| .. code-block:: bash |
| |
| $sudo dd if=build/flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync |
| |
| Boot |
| ---- |
| |
| Set Boot switch to SD boot |
| Use /dev/ttyUSB2 for U-Boot console |
