SK-AM69: OPTEE List of Trusted Applications in Default j784s4 Image

Part Number: SK-AM69
Other Parts Discussed in Thread: AM69

Tool/software:

Hello,

I am using the Linux SDK for the AM69 board and the tisdk-default-image-j784s4-evm image for investigation.  Under this I am looking into OPTEE and trusted applications.  After reading the documents of OPTEE it pointed me to the /lib/optee_armtz/ directory where the trusted applications are loaded from.  The OPTEE reading says each file would correlate to a single trusted application.  When building OPTEE using u-boot's documentation, there are only 4 .ta files, but TI's SDK has several .ta files.

Could someone point me to information on what all these trusted applications are in the TI SDK?

    Hi Wayne,

    TI uses the stock optee-examples that come with OPTEE. TI itself does not provide any specific Trusted Applications.

    optee-examples is a separate git tree by itself from the optee-os.

    regards
