Quick Start
|
|
===========
|
|
- Build the ARM Trusted firmware binary
|
|
- Get ddr firmware
|
|
- Build U-Boot
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
======================================
|
|
Note: $(srctree) is U-Boot source directory
|
|
|
|
$ git clone https://source.codeaurora.org/external/imx/imx-atf
|
|
$ git checkout imx_4.19.35_1.0.0
|
|
$ make PLAT=imx8mm bl31 ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ cp build/imx8mm/release/bl31.bin $(srctree)
|
|
|
|
Get the DDR firmware
|
|
====================
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.5.bin
|
|
$ chmod +x firmware-imx-8.5.bin
|
|
$ ./firmware-imx-8.5
|
|
$ cp firmware-imx-8.5/firmware/ddr/synopsys/lpddr4*.bin $(srctree)
|
|
|
|
Build U-Boot
|
|
============
|
|
$ make imx8mm_beacon_defconfig
|
|

|
|
|
|
Burn U-Boot to microSD Card
|
|
===========================
|
|
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33
