CAAM API integration with U-Boot

kanimozhi_t — Mon, 05 Jul 2021 08:54:27 GMT

Hi,

We would like to use CAAM for hash calculation and comparison on U-Boot. We know that we can use HAB APIs to utilise the CAAM internally but we're interested in using the CAAM directly for the above mentioned tasks.

1. Is CAAM API available for public use? If so, where can we find the documentation?

2. How can we integrate CAAM API on U-Boot? Are there any examples?

Any suggestions would highly be appreciated.

Hello,

we do not support CAAM API for U-boot. Only Linux interface is available.

Regards,
Yuri.

BTW, can you share the links for CAAM Linux API?
