Does a TF-M sample exist for LPC55S69

I'm looking to run the TF-M project on the LPC55S69. Is there any such example project to take advantage of the ARMv8 architecture?

So I've discovered that if I generate the SDK for Keil uVision then a TF-M application is generated, however without mcu-boot which is part of the TF-M application. That leaves me with 2 questions:

1. Should / will mcuXpresso support this example?

2. Is there a BL2 sample implementation available?

Hi Daniel,

If you're refering to the Trustzone examples, that ones are also supported in MCUXpresso. Also, what do you mean with with BL2?

Hi Alexis,

1.Okay thanks, it seems like this may be a bug with the SDK generator then, since the project is only packaged when using uVision

2. BL2= 2nd stage bootloader. TF-M uses mcuboot for this to do image verification and firmware update ( http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-223.pdf )

Hi Daniel,

You're right, this examples aren't generated in the MCUXpresso version. I will report this to our SDK team.
