| 6 | U-Boot for the NXP i.MX8MP EVK board |
| 7 | |
| 8 | Quick Start |
| 9 | ----------- |
| 10 | |
| 11 | - Build the ARM Trusted firmware binary |
| 12 | - Get the firmware-imx package |
| 13 | - Build U-Boot |
| 14 | - Boot |
| 15 | |
| 16 | Get and Build the ARM Trusted firmware |
| 17 | -------------------------------------- |
| 18 | |
| 19 | Note: $(srctree) is the U-Boot source directory |
| 20 | Get ATF from: https://source.codeaurora.org/external/imx/imx-atf |
| 21 | branch: imx_5.4.3_2.0.0 |
| 22 | |
| 23 | .. code-block:: bash |
| 24 | |
| 25 | $ make PLAT=imx8mp bl31 |
| 26 | $ sudo cp build/imx8mp/release/bl31.bin $(srctree) |
| 27 | |
| 28 | Get the ddr firmware |
| 29 | -------------------- |
| 30 | |
| 31 | .. code-block:: bash |
| 32 | |
| 33 | $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin |
| 34 | $ chmod +x firmware-imx-8.7.bin |
| 35 | $ ./firmware-imx-8.7 |
| 36 | $ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin |
| 37 | $ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin |
| 38 | $ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin |
| 39 | $ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin |
| 40 | |
| 41 | Build U-Boot |
| 42 | ------------ |
| 43 | |
| 44 | .. code-block:: bash |
| 45 | |
| 46 | $ export CROSS_COMPILE=aarch64-poky-linux- |
| 47 | $ make imx8mp_evk_defconfig |
| 48 | $ export ATF_LOAD_ADDR=0x960000 |
| 49 | $ make flash.bin |
| 50 | |
| 51 | Burn the flash.bin to the MicroSD card at offset 32KB: |
| 52 | |
| 53 | .. code-block:: bash |
| 54 | |
| 55 | $sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync |
| 56 | |
| 57 | Boot |
| 58 | ---- |
| 59 | |
| 60 | Set Boot switch to SD boot |
| 61 | Use /dev/ttyUSB2 for U-Boot console |
