TMDX654GPEVM: OP-TEE development

Thank you Andrew, that is good news.

Just for my reference, can you point me to the documentation that you referred to, and particularly, any that explains the differences between the GP and HS devices?

Actually, if you are in contact with the relevant people, it might be worth passing the suggestion of making that information more readily available to prevent other people getting confused in the same way. The datasheet and TRM only seems to mention the HS to state that it enforces secure boot (section 6.4.1), which I thought was the only difference. And the AM6526 page does not show any HS variants of the silicon in the parametric family list, and it does not show the HS EVM either.

Thank you again for your support.

Best regards,

Jose

Hi Jose,

I was not referring to any one piece of documentation specifically, but rather our documentation strategy for HS devices in general. We start with the full TRM then break out anything HS specific into an HS addendum, which we give out when purchasing the HS variant, usually though a separate "MySecureSoftware" portal.

For this class of device the difference between an HS and GP is very minimal, mostly related to the keys efused into the device, without those on GP, secure boot is not enforced, as you've found in the documents.

The HS versions of the device are usually launched to the broader-market customers after we bring the non-HS versions out of pre-production stage, so they might not be available yet, which would explain the HS variants not being listed on all the family lists.

Thanks,

Andrew

Thanks Andrew! That clarifies :)
