This adds support for the IOT2050 Basic and Advanced devices. The Basic used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS quad-core version. Both variants are booted via a Siemens-provided FSBL that runs on the R5 cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot SPL, ATF and TEE have to reside in SPI flash. Full integration into a bootable image can be found on https://github.com/siemens/meta-iot2050 Based on original board support by Le Jin, Gao Nian and Chao Zeng.

SIMATIC IOT2050 BASIC and ADVANCED
|
|
==================================
|
|
|
|
The SIMATIC IOT2050 is an open industrial IoT gateway that is using the TI
|
|
AM6528 GP (Basic variant) or the AM6548 HS (Advanced variant). The Advanced
|
|
variant is prepared for secure boot.
|
|
|
|
The IOT2050 starts only from OSPI. It loads a Siemens-provided bootloader
|
|
called SE-Boot for the MCU domain (R5F cores), then hands over to ATF and
|
|
OP-TEE, before booting U-Boot on the A53 cores. This describes how to build all
|
|
open artifacts into a flashable image for the OSPI flash. The flash image will
|
|
work on both variants.
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
ATF: Upstream release 2.4 or newer
|
|
OP-TEE: Upstream release 3.10.0 or newer
|
|
|
|
Binary dependencies can be found in
|
|
https://github.com/siemens/meta-iot2050/tree/master/recipes-bsp/u-boot/files/prebuild.
|
|
The following binaries from that source need to be present in the build folder:
|
|
|
|
- tiboot3.bin
|
|
- sysfw.itb
|
|
- sysfw.itb_HS
|
|
- sysfw_sr2.itb
|
|
- sysfw_sr2.itb_HS
|

|
Building
|
|
--------
|
|
|
|
Make sure that CROSS_COMPILE is set appropriately:
|
|
|
|
.. code-block:: text
|
|
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
|
|
|
ATF:
|
|
|
|
.. code-block:: text
|
|
|
|
$ make PLAT=k3 SPD=opteed K3_USART=1
|
|
|
|
OP-TEE:
|
|
|
|
.. code-block:: text
|
|
|
|
$ make PLATFORM=k3-am65x CFG_ARM64_core=y CFG_TEE_CORE_LOG_LEVEL=2 CFG_CONSOLE_UART=1
|
|
|
|
U-Boot:
|
|
|
|
.. code-block:: text
|
|
|
|
$ export ATF=/path/to/bl31.bin
|
|
$ export TEE=/path/to/tee-pager_v2.bin
|
|
$ make iot2050_defconfig
|
|
$ make
|
|
|
|
Flashing
|
|
--------
|
|
|
|
Via U-Boot:
|
|
|
|
.. code-block:: text
|
|
|
|
IOT2050> sf probe
|
|
IOT2050> load mmc 0:1 $loadaddr /path/to/flash.bin
|
|
IOT2050> sf update $loadaddr 0x0 $filesize
|
|
|
|
Via external programmer Dediprog SF100 or SF600:
|
|
|
|
.. code-block:: text
|
|
|
|
$ dpcmd --vcc 2 -v -u flash.bin
|
