Verdin AM62 Module
==================
Quick Start
-----------
- Get the binary-only SYSFW
- Get binary-only TI Linux firmware
- Build the ARM trusted firmware binary
- Build the OPTEE binary
- Build U-Boot for the R5
- Build U-Boot for the A53
- Flash to eMMC
- Boot
For an overview of the TI AM62 SoC boot flow please head over to:
.. file:: ../ti/am62x_sk.rst
Get the SYSFW
-------------
.. code-block:: bash
$ echo "Downloading SYSFW..."
$ git clone git://git.ti.com/k3-image-gen/k3-image-gen.git
Get the TI Linux Firmware
-------------
.. code-block:: bash
$ echo "Downloading TI Linux Firmware..."
$ git clone -b ti-linux-firmware git://git.ti.com/processor-firmware/ti-linux-firmware.git
Get and Build the ARM Trusted Firmware (Trusted Firmware A)
-----------------------------------------------------------
.. code-block:: bash
$ echo "Downloading and building TF-A..."
$ git clone https://github.com/ARM-software/arm-trusted-firmware.git
$ cd arm-trusted-firmware
Then build ATF (TF-A):
.. code-block:: bash
$ export ARCH=aarch64
$ export CROSS_COMPILE=aarch64-none-linux-gnu-
$ make PLAT=k3 TARGET_BOARD=lite SPD=opteed
Get and Build OPTEE
-------------------
.. code-block:: bash
$ echo "Downloading and building OPTEE..."
$ git clone https://github.com/OP-TEE/optee_os.git
$ cd optee_os
Then build OPTEE:
.. code-block:: bash
$ export CROSS_COMPILE=arm-none-linux-gnueabihf-
$ export CROSS_COMPILE64=aarch64-none-linux-gnu-
$ make PLATFORM=k3 CFG_ARM64_core=y
Build U-Boot for R5
-------------------
.. code-block:: bash
$ export ARCH=arm
$ export CROSS_COMPILE=arm-none-linux-gnueabihf-
$ make verdin-am62_r5_defconfig
$ make BINMAN_INDIRS=<path/to/ti-linux-firmware>
Build U-Boot for A53
--------------------
.. code-block:: bash
$ export ARCH=arm64
$ export CROSS_COMPILE=aarch64-none-linux-gnu-
$ make verdin-am62_a53_defconfig
$ make BL31=<path to ATF dir>/build/k3/lite/release/bl31.bin \
TEE=<path to OPTEE OS dir>/out/arm-plat-k3/core/tee-pager_v2.bin \
BINMAN_INDIRS=<path/to/ti-linux-firmware>
Flash to eMMC
-------------
.. code-block:: bash
=> mmc dev 0 1
=> fatload mmc 1 ${loadaddr} tiboot3.bin
=> mmc write ${loadaddr} 0x0 0x400
=> fatload mmc 1 ${loadaddr} tispl.bin
=> mmc write ${loadaddr} 0x400 0x1000
=> fatload mmc 1 ${loadaddr} u-boot.img
=> mmc write ${loadaddr} 0x1400 0x2000
Boot
