- ==========
- 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
- --------------------------------------
- Note: $(srctree) is the U-Boot source directory
- Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
- branch: imx_5.4.3_2.0.0
- .. code-block:: bash
- $ make PLAT=imx8mp bl31
- $ cp build/imx8mp/release/bl31.bin $(srctree)
- Get the ddr firmware
- --------------------
- .. code-block:: bash
- $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin
- $ chmod +x firmware-imx-8.7.bin
- $ ./firmware-imx-8.7.bin
- $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
- $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
- $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
- $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin
- Build U-Boot
- ------------
- .. code-block:: bash
- $ export CROSS_COMPILE=aarch64-poky-linux-
- $ make imx8mp_evk_defconfig
- $ export ATF_LOAD_ADDR=0x960000
- $ make flash.bin
- Burn the flash.bin to the MicroSD card at offset 32KB:
- .. code-block:: bash
- $sudo dd if=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
