+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
+.. include:: ../ti/k3.rst
- :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
+.. 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
+.. include:: ../ti/am62x_sk.rst
- :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 as tiboot3.bin +* tispl.bin_unsigned from Cortex-A build as tispl.bin +* u-boot.img_unsigned from Cortex-A build as u-boot.img
Is the _unsigned really required? I guess the regular tispl and u-boot.img should also work right? It will just skip auth I guess.

Mostly looks good, thanks! Reviewed-by: Dhruva Gole d-gole@ti.com
