-U-Boot for the NXP i.MX8MQ EVK board
-
-Quick Start
-===========
-
-- Build U-Boot
-- Build the ARM Trusted firmware binary
-- Get DDR firmware and mkimage tool
-- Generate flash.bin using imx-mkimage
-- Flash the binary into the SD card
-- Boot
-
-Build U-Boot
-============
-
-$ make mx8mq_evk_defconfig
-$ make
-
-Get and Build the ARM Trusted firmware
-======================================
-
-$ git clone https://source.codeaurora.org/external/imx/imx-atf
-$ cd imx-atf/
-$ git checkout origin/imx_4.9.51_imx8m_beta
-$ make PLAT=imx8mq bl31
-
-Get the DDR firmware and mkimage tool
-==============================
-
-$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.2.bin
-$ chmod +x firmware-imx-7.2.bin
-$ ./firmware-imx-7.2.bin
-
-Download the imx-mkimage tool:
-
-$ git clone https://source.codeaurora.org/external/imx/imx-mkimage/
-$ cd imx-mkimage/
-$ git checkout origin/imx_4.9.51_imx8m_beta
-
-
-Generate flash.bin using imx-mkimage
-====================================
-
-Copy the following binaries to imx-mkimage/iMX8M folder:
-
-$ cp imx-atf/build/imx8mq/release/bl31.bin imx-mkimage/iMX8M/
-$ cp u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/
-$ cp u-boot/spl/u-boot-spl.bin imx-mkimage/iMX8M/
-$ cp u-boot/arch/arm/dts/fsl-imx8mq-evk.dtb imx-mkimage/iMX8M/
-
-Copy the following firmwares to imx-mkimage/iMX8 folder :
-
-$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem.bin imx-mkimage/iMX8M/
-$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem.bin imx-mkimage/iMX8M/

-$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem.bin imx-mkimage/iMX8M/
-
-If you want to run with HDMI, copy signed_hdmi_imx8m.bin to imx-mkimage/iMX8M.
-
-Before generating the flash.bin, transfer the mkimage generated by U-Boot to iMX8M folder:
-
-$ cp u-boot/tools/mkimage imx-mkimage/iMX8M/
-$ mv imx-mkimage/iMX8M/mkimage imx-mkimage/iMX8M/mkimage_uboot
-
-$ cd imx-mkimage/
-$ make SOC=iMX8M flash_spl_uboot
-
-Or for using HDMI:
-
-$ make SOC=iMX8M flash_hdmi_spl_uboot
-
-Flash the binary into the SD card
-=================================
-
-Burn the flash.bin binary to SD card offset 33KB:
-
-$ sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33
-
-Boot
-====
-Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
