U-Boot for the BSH SystemMaster (SMM) S2 board family.
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
- Build the ARM Trusted firmware binary
|
|
- Get firmware-imx package
|
|
- Build U-Boot
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
--------------------------------------
|
|
|
|
Note: srctree is U-Boot source directory
|
|
Get ATF from: https://github.com/ARM-software/arm-trusted-firmware
|
|
tag: v2.5
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make PLAT=imx8mn IMX_BOOT_UART_BASE=0x30a60000 bl31
|
|
$ cp build/imx8mn/release/bl31.bin $(srctree)
|
|
|
|
Get the ddr firmware
|
|
--------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
|
|
$ chmod +x firmware-imx-8.9.bin
|
|
$ ./firmware-imx-8.9
|
|
$ cp firmware-imx-8.9/firmware/ddr/synopsys/ddr3*.bin $(srctree)
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ make imx8mn_bsh_smm_s2_defconfig
|
|
$ make
|
|
|
|
Burn the flash.bin to MicroSD card offset 32KB:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 conv=notrunc
|
|
|
|
Boot
|
|
----
|
|
|
|
Start the board in USB serial downloader mode, plug-in the USB-OTG port and
|
|
load flash.bin using Freescale/NXP UUU tool:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ uuu -v flash.bin
