|
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:

|
|
:end-before: .. k3_rst_include_end_board_env_vars_desc
|
|
|
|
Set the variables corresponding to this platform:
|

|
|
.. include:: ../ti/k3.rst
|
|
:start-after: .. k3_rst_include_start_common_env_vars_defn

$ export UBOOT_CFG_CORTEXA=verdin-am62_a53_defconfig
|
|
$ export TFA_BOARD=lite
|
|
$ # we don't use any extra TFA parameters
|

$ unset TFA_EXTRA_ARGS

|
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 having to remember all those addresses and sizes,
|
|
one may also use the update U-Boot wrappers:
|
|
|
|
.. code-block:: bash
|
|
|
|
> tftpboot ${loadaddr} tiboot3-am62x-gp-verdin.bin
|
|
> run update_tiboot3
|
|
|
|
> tftpboot ${loadaddr} tispl.bin
|
|
> run update_tispl
|
|
|
|
> tftpboot ${loadaddr} u-boot.img
|
|
> run update_uboot
|
|
|
|
