imx8mm-u-boot.dtsi passes the ATF load address via the 'entry' and 'load' properties. Remove the step that performs the ATF_LOAD_ADDR export, which is now unneeded. Signed-off-by: Fabio Estevam <festevam@denx.de> Reviewed-by: Patrick Wildt <patrick@blueri.se>

Kontron Electronics SL i.MX8MM SoM
|
|
==================================
|
|
|
|
The Kontron SoM-Line i.MX8MM (N801x) by Kontron Electronics GmbH is a SoM module
|
|
with an i.MX8M-Mini SoC, 1/2/4 GB LPDDR4 RAM, SPI NOR, eMMC and PMIC.
|
|
|
|
The matching evaluation boards (Board-Line) have two Ethernet ports, USB 2.0,
|
|
HDMI/LVDS, SD card, CAN, RS485, RS232 and much more.
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
- Get and Build the Trusted Firmware-A (TF-A)
|
|
- Get the DDR firmware
|
|
- Build U-Boot
|
|
- Boot
|
|
|
|
Get and Build the Trusted Firmware-A (TF-A)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Note: builddir is U-Boot build directory (source directory for in-tree builds)
|
|
|
|
There are two sources for the TF-A. Mainline and NXP. Get the one you prefer
|
|
(support and features might differ).
|
|
|
|
**NXP's imx-atf**
|
|
|
|
1. Get TF-A from: https://source.codeaurora.org/external/imx/imx-atf, branch: imx_5.4.70_2.3.0
|
|
2. Apply the patch to select the correct UART for the console, otherwise the TF-A will lock up during boot.
|
|
3. Build
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make PLAT=imx8mm bl31
|
|
$ cp build/imx8mm/release/bl31.bin $(builddir)
|
|
|
|
**Mainline TF-A**
|
|
|
|
1. Get TF-A from: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/, tag: v2.4
|
|
2. Build
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make PLAT=imx8mm CROSS_COMPILE=aarch64-linux-gnu- IMX_BOOT_UART_BASE="0x30880000" bl31
|
|
$ cp build/imx8mm/release/bl31.bin $(builddir)
|
|
|
|
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 $(builddir)
|
|
|
|
Build U-Boot
|
|
^^^^^^^^^^^^
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make kontron-sl-mx8mm_defconfig
|
|
$ make
|
|
|
|
Burn the flash.bin to SD card at an offset of 33 KiB:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ dd if=flash.bin of=/dev/sd[x] bs=1K seek=33 conv=notrunc
|
|
|
|
Boot
|
|
^^^^
|
|
|
|
Put the SD card in the slot on the board and apply power.
|
|
|

|
-------------------
|
|
|
|
The bootloader configuration is setup to be used with kernel FIT images. Legacy
|
|
images might not be working out of the box.
