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_dmem.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.
