| 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 CFG_USER_TA_TARGETS="ta_arm64" |
| |
| 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 |
