Update the venice board documentation to show how to install to the various eMMC hardware partitions available as the same binary firmware can be placed in either user/boot0/boot1 without build-time config changes. Note that the boot offsets differ depending on the SoC and the eMMC hardware partition. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

|
|
-----------
|
|
- Build the ARM Trusted firmware binary
|
|
- Get DDR firmware
|
|
- Build U-Boot
|
|
- Flash to eMMC
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
--------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/nxp-imx/imx-atf.git -b lf_v2.4
|
|
$ make PLAT=imx8mp bl31 CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ cp build/imx8mp/release/bl31.bin .
|
|
|
|
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.bin
|
|
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make imx8mp_venice_defconfig
|
|
$ make CROSS_COMPILE=aarch64-linux-gnu-
|
|
|
|
Update eMMC
|
|
-----------
|
|
|
|
.. code-block:: bash
|
|
|
|
=> tftpboot $loadaddr flash.bin
|
|
=> setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200
|
|
=> mmc dev 2 0 && mmc write $loadaddr 0x40 $blkcnt # emmc user hw part
|
|
=> mmc dev 2 1 && mmc write $loadaddr 0 $blkcnt # or emmc boot0 hw part
|
|
=> mmc dev 2 2 && mmc write $loadaddr 0 $blkcnt # or emmc boot1 hw part
