  3. ==========
  4. U-Boot for the NXP i.MX8MM EVK board
  5. Quick Start
  6. -----------
  7. - Build the ARM Trusted firmware binary
  8. - Get ddr firmware
  9. - Build U-Boot
  10. - Boot
  11. Get and Build the ARM Trusted firmware
  12. --------------------------------------
  13. Note: builddir is U-Boot build directory (source directory for in-tree builds)
  14. Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
  15. branch: imx_4.19.35_1.0.0
  16. .. code-block:: bash
  17. $ make PLAT=imx8mm bl31
  18. $ cp build/imx8mm/release/bl31.bin $(builddir)
  19. Get the ddr firmware
  20. --------------------
  21. .. code-block:: bash
  22. $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
  23. $ chmod +x firmware-imx-8.0.bin
  24. $ ./firmware-imx-8.0
  25. $ cp firmware-imx-8.0/firmware/ddr/synopsys/lpddr4*.bin $(builddir)
  26. Build U-Boot
  27. ------------
  28. .. code-block:: bash
  29. $ export CROSS_COMPILE=aarch64-poky-linux-
  30. $ make imx8mm_evk_defconfig
  31. $ export ATF_LOAD_ADDR=0x920000
  32. $ make flash.bin
  33. Burn the flash.bin to MicroSD card offset 33KB:
  34. .. code-block:: bash
  35. $sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33 conv=notrunc
  36. Boot
  37. ----
  38. Set Boot switch to SD boot
