Using ArmTF-Test SP/SPD with Juno

Hi experts  ,

I configured my Juno board as this instruction and my workspace is initialized by the script from that page too.

Now I met some unknown issues when setting secure timer for my board. I find the ARM-TF provides a test secure payload and they utilize the secure timer so I want to try this payload to confirm my board's timer works well.

In this case, I'm wondering can I still use the workspace I got to build the TSP for Juno board?

If I can, could you please give me some hints about how to modify the build scripts? If I can't, is there any other instructions about applying the TSP on Juno?

Thank you in advance.

  • Hi Simon,

    It looks like the UART is being misconfigured on Juno.

    If you navigate to `<workspace>/arm-tf/include/plat/arm/board/common' and apply these 2 patches you'll see the TSP printing messages to UART1 (the bottom UART) as expected:

    v2m_def.patch     board_css_def.patch

    For example:

    I'll poke the ARM Trusted Firmware development team about this to see whether it's a known issue.
