phyCORE-AM64x
|
||||
=============
|
||||
|
||||
The `phyCORE-AM64x <https://www.phytec.com/product/phycore-am64x>`_ is a
|
||||
SoM (System on Module) featuring TI's AM64x SoC. It can be used in combination
|
||||
with different carrier boards. This module can come with different sizes and
|
||||
models for DDR, eMMC, SPI NOR Flash and various SoCs from the AM64x family.
|
||||
|
||||
A development Kit, called `phyBOARD-Lyra <https://www.phytec.com/product/phyboard-am64x>`_
|
||||
is used as a carrier board reference design around the AM64x SoM.
|
||||
|
||||

|
||||
|
||||

|

|
||||
Build procedure
|
||||
---------------
|
||||
|
||||
Setup the environment variables:
|
||||
|
||||
.. include:: ../ti/k3.rst
|
||||
:start-after: .. k3_rst_include_start_common_env_vars_desc
|
||||
:end-before: .. k3_rst_include_end_common_env_vars_desc
|

|
||||
: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
|
||||
:end-before: .. k3_rst_include_end_common_env_vars_defn
|
||||
.. code-block:: bash
|
||||
|
||||
$ export UBOOT_CFG_CORTEXR=phycore_am64x_r5_defconfig
|
||||
$ export UBOOT_CFG_CORTEXA=phycore_am64x_a53_defconfig
|
||||
$ export TFA_BOARD=lite
|
||||
$ # we don't use any extra TFA parameters
|
||||
$ unset TFA_EXTRA_ARGS
|
||||
$ export OPTEE_PLATFORM=k3-am64x
|
||||
# we don't use any extra OPTEE parameters
|
||||
unset OPTEE_EXTRA_ARGS

:end-before: .. am62x_evm_rst_include_end_build_steps
|
||||
|
||||
uSD Card creation
|
||||
-----------------
|
||||
|
||||
Use fdisk to partition the uSD card. The layout should look similar to:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo fdisk -l /dev/mmcblk0
|
||||
Disk /dev/mmcblk0: 7.56 GiB, 8120172544 bytes, 15859712 sectors
|
||||
Units: sectors of 1 * 512 = 512 bytes
|
||||
Sector size (logical/physical): 512 bytes / 512 bytes
|
||||
I/O size (minimum/optimal): 512 bytes / 512 bytes
|
||||
Disklabel type: dos
|
||||
Disk identifier: 0x6583d9a3
|
||||
|
||||
Device Boot Start End Sectors Size Id Type
|
||||
/dev/mmcblk0p1 * 2048 264191 262144 128M c W95 FAT32 (LBA)
|
||||
/dev/mmcblk0p2 264192 1934953 1670762 815.8M 83 Linux
|
||||
|
||||
|
||||
Once partitioned, the boot partition has to be formatted with a FAT filesystem.
|
||||
Assuming the uSD card is `/dev/mmcblk0`:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ mkfs.vfat /dev/mmcblk0p1
|
||||
|
||||
To boot from a micro SD card on a HSFS device simply copy the following
|
||||
artifacts to the FAT partition:
|
||||
|
||||
* tiboot3.bin from R5 build
|
||||
* tispl.bin from Cortex-A build
|
||||
* u-boot.img from Cortex-A build
|
||||
|
||||
Boot
|
||||
----
|
||||
|
||||
Put the uSD card in the slot on the board and apply power. Check the serial
|
||||
console for output.
|
||||
|
||||
Flash to SPI NOR
|
||||
----------------
|
||||
|
||||
Below commands can be used to flash the SPI NOR flash; assuming
|
||||
tiboot3.bin, tispl.bin and u-boot.img are stored on the uSD card.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
sf probe
|
||||
fatload mmc 1 ${loadaddr} tiboot3.bin
|
||||
sf update $loadaddr 0x0 $filesize
|
||||
fatload mmc 1 ${loadaddr} tispl.bin
|
||||
sf update $loadaddr 0x80000 $filesize
|
||||
fatload mmc 1 ${loadaddr} u-boot.img
|
||||
sf update $loadaddr 0x280000 $filesize
|
||||
|
||||
|
||||
Boot Modes
|
||||
----------
|
||||
|
||||
The phyCORE-AM64x development kit supports booting from many different
|
||||
interfaces. By default, the development kit is set to boot from the micro-SD
|
||||
card. To change the boot device, DIP switches S5 and S6 can be used.
|
||||
Boot switches should be changed with power off.
