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
Note: Currently, not buildable with gcc-12.2 please revert to using gcc-11.3.
Note: Currently, latest master is broken please revert to using 2fcd408bb3a6756767a43c073c597cef06e7f2d5.
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 O=/tmp/r5
$ make O=/tmp/r5
$ cd ../k3-image-gen
$ make SOC=am62x SBL=/tmp/r5/spl/u-boot-spl.bin SYSFW_PATH=../ti-linux-firmware/ti-sysfw/ti-fs-firmware-am62x-gp.bin
$ cp tiboot3-am62x-gp-evm.bin ../tiboot3.bin
Build U-Boot for A53
--------------------
.. code-block:: bash
$ export ARCH=arm64
$ export CROSS_COMPILE=aarch64-none-linux-gnu-
$ make verdin-am62_a53_defconfig O=/tmp/a53
$ make ATF=$PWD/../arm-trusted-firmware/build/k3/lite/release/bl31.bin TEE=$PWD/../optee_os/out/arm-plat-k3/core/tee-pager_v2.bin DM=$PWD/../ti-linux-firmware/ti-dm/am62xx/ipc_echo_testb_mcu1_0_release_strip.xer5f O=/tmp/a53
$ cp /tmp/a53/tispl.bin ../
$ cp /tmp/a53/u-boot.img ../
Note: Relative paths to the artefacts are known to not work.
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
As a convenience, instead of those commands one may also use the update U-Boot
wrapper:
.. code-block:: bash
> run update_uboot
Boot
