|
||
|
|
|
||
|
|
Quick Start
|
||
|
|
===========
|
||
|
|
- Build the ARM Trusted firmware binary
|
||
|
|
- Get the firmware-imx package
|
||
|
|
- Build U-Boot
|
||
|
|
- Boot
|
||
|
|
|
||
|
|
Get and Build the ARM Trusted firmware
|
||
|
|
======================================
|
||
|
|
Note: $(srctree) is the U-Boot source directory
|
||
|
|
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
|
||
|
|
branch: imx_5.4.3_2.0.0
|
||
|
|
$ make PLAT=imx8mp bl31
|
||
|
|
$ sudo cp build/imx8mp/release/bl31.bin $(srctree)
|
||
|
|
|
||
|
|
Get the ddr firmware
|
||
|
|
====================

|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin
|
||
|
|
$ chmod +x firmware-imx-8.7.bin
|
||
|
|
$ ./firmware-imx-8.7
|
||
|
|
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
|
||
|
|
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
|
||
|
|
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
|
||
|
|
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin

|
Build U-Boot
|
||
|
|
============
|
||
|
|
$ export CROSS_COMPILE=aarch64-poky-linux-
|
||
|
|
$ make imx8mp_evk_defconfig
|
||
|
|
$ export ATF_LOAD_ADDR=0x960000
|
||
|
|
$ make flash.bin
|
||
|
|
|
||
|
|
Burn the flash.bin to the MicroSD card at offset 32KB
|
||
|
|
$sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32; sync
