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
|
|
--------------------------------------
|
|
|
|
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
|
|
branch: imx_5.4.70_2.3.0
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make PLAT=imx8mp bl31
|
|
|
|
Get the ddr firmware
|
|
--------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.bin
|
|
$ chmod +x firmware-imx-8.10.bin
|
|
$ ./firmware-imx-8.10.bin
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-poky-linux-
|
|
$ make O=build imx8mp_evk_defconfig
|
|
$ cp ../imx-atf/build/imx8mp/release/bl31.bin ./build/bl31.bin
|
|
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_202006.bin ./build/
|
|
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_202006.bin ./build/
|
|
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_202006.bin ./build/
|
|
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_202006.bin ./build/
|
|
$ export ATF_LOAD_ADDR=0x970000
|
|
$ make O=build
|
|
|
|
Burn the flash.bin to the MicroSD card at offset 32KB:
|
|
|
|
.. code-block:: bash
|
|
|
|
$sudo dd if=build/flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
|
|
$sudo dd if=build/u-boot.itb of=/dev/sd[x] bs=1K seek=384 conv=notrunc; sync
|
|
|
|
Boot
