  2. imx8mp_evk
  3. ==========
  4. U-Boot for the NXP i.MX8MP EVK board
  5. Quick Start
  6. -----------
  7. - Build the ARM Trusted firmware binary
  8. - Get the firmware-imx package
  9. - Build U-Boot
  10. - Boot
  11. Get and Build the ARM Trusted firmware
  12. --------------------------------------
  13. Note: $(srctree) is the U-Boot source directory
  14. Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
  15. branch: imx_5.4.3_2.0.0
  16. .. code-block:: bash
  17. $ make PLAT=imx8mp bl31
  18. $ cp build/imx8mp/release/bl31.bin $(srctree)
  19. Get the ddr firmware
  20. --------------------
  21. .. code-block:: bash
  22. $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin
  23. $ chmod +x firmware-imx-8.7.bin
  24. $ ./firmware-imx-8.7.bin
  25. $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
  26. $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
  27. $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
  28. $ cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin
  29. Build U-Boot
  30. ------------
  31. .. code-block:: bash
  32. $ export CROSS_COMPILE=aarch64-poky-linux-
  33. $ make imx8mp_evk_defconfig
  34. $ export ATF_LOAD_ADDR=0x960000
  35. $ make flash.bin
  36. Burn the flash.bin to the MicroSD card at offset 32KB:
  37. .. code-block:: bash
  38. $sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
  39. Boot
  40. ----
  41. Set Boot switch to SD boot
  42. Use /dev/ttyUSB2 for U-Boot console
