- ==========
- 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
- $sudo dd if=build/u-boot.itb of=/dev/sd[x] bs=1K seek=384 conv=notrunc; sync
- Boot
- ----
- Set Boot switch to SD boot
- Use /dev/ttyUSB2 for U-Boot console
