Corstone-300 Ethos-U55 FPGA and FVP¶

Building TF-M¶

Follow the instructions in Building instructions. Build instructions with platform name: mps3/an547 (-DTFM_PLATFORM=mps3/an547).

Note

This platform support does not provide software for Ethos-U55 IP, only contains base address and interrupt number for it.

Note

The built binaries can be run on both the Corstone-300 Ethos-U55 Ecosystem FVP (FVP_SSE300_MPS3) and Corstone SSE-300 with Ethos-U55 Example Subsystem for MPS3 (AN547).

To run the example code on Corstone SSE-300 with Ethos-U55 Example Subsystem for MPS3 (AN547)¶

FPGA image is available to download here

To run BL2 bootloader and TF-M example application and tests in the MPS3 board, it is required to have AN547 image in the MPS3 board SD card. The image should be located in <MPS3 device name>/MB/HBI<BoardNumberBoardrevision>/AN547

The MPS3 board tested is HBI0309C.

Copy bl2.bin and tfm_s_ns_signed.bin files from build dir to <MPS3 device name>/SOFTWARE/
Rename tfm_s_ns_signed.bin to tfm.bin (Filename should not be longer than 8 charachters.)
Open <MPS3 device name>/MB/HBI0309C/AN547/images.txt

Update the images.txt file as follows:

Close <MPS3 device name>/MB/HBI0309C/AN547/images.txt
Unmount/eject the <MPS3 device name> unit
Reset the board to execute the TF-M example application

After completing the procedure you should be able to visualize on the serial port (baud 115200 8n1) the following messages:

[INF] Swap type: none
[INF] Swap type: none

To run the example code on Corstone-300 Ethos-U55 Ecosystem FVP¶

FVP is available to download here

Install the FVP
Copy bl2.axf and tfm_s_ns_signed.bin files from build dir to <FVP installation path>/models/Linux64_GCC-6.4/
Navigate to the same directory and execute the following command to start FVP:

./FVP_MPS3_Corstone_SSE-300 -a cpu0*=”bl2.axf” –data “tfm_s_ns_signed.bin”@0x01000000

After completing the procedure you should be able to visualize on the serial port the following messages:
