+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.
+
+Quickstart
+----------
+
+* Download sources and TI firmware blobs
+* Build Trusted Firmware-A
+* Build OP-TEE
+* Build U-Boot for the R5
+* Build U-Boot for the A53
+* Create bootable uSD Card
+* Boot
+
+Sources
+-------
+
+.. include:: ../ti/k3.rst
+ :start-after: .. k3_rst_include_start_boot_sources
+ :end-before: .. k3_rst_include_end_boot_sources
+
+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

+ :start-after: .. k3_rst_include_start_board_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

+ $ 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

+ :start-after: .. am62x_evm_rst_include_start_build_steps
+ :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.
