When using cygwin64 "dd (coreutils) 8.26 Packaged by Cygwin (8.26-2)", the last not 512bytes aligned data wat cut off and not burned into SD card. Saying the flash.bin size is 1085608 bytes, not 512bytes aligned. It only burned 1085440 bytes, the leaving 168 bytes were not burnned and cause boot issue. So update README dd command to add "conv=notrunc" Signed-off-by: Peng Fan <peng.fan@nxp.com>

U-Boot for the NXP i.MX8MP EVK board
|
|
|
|
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 conv=notrunc; sync
|
|
|
|
Boot
|
|
====
|
|
Set Boot switch to SD boot
|
|
Use /dev/ttyUSB2 for U-Boot console
