i.MX91/93: secure provisioning and SVD file

[svoulaz_ik]

Hello,

is there any chance that NXP will support in the near future Secure Provisioning for i.MX91 and i.MX93? Also, will the SVD file for those CPUs be ever released?

We are approaching a challenging tentative to use the i.MX91 bare metal (no u-boot, no linux), maybe just running FreeRTOS, but at the moment this seems a very remote possibility - no flashloader, no SVD file, no debugger support.

I'm aware that using an A55 bare metal looks weird, but - if ever possible - this would open a range of possibilities in computing-intensive tasks for several applications.

Thank you in advance.
Best regards,

Stefano

Hello,

There are no plans to support Secure Provisioning in MPU i.MX devices.

Regarding SVD files, can be requested in our support tickets but you need an NDA as a requirement to access to SVD files.

When you are developing a BareMetal applications in our MPUs, you have to take in mind several module initializations and handlings under BareMetal as is done in our Linux BSP, this process is under your own risk since we do not have documentation or support for BareMetal in Cortex-A.

If you are developing this design in Cortex-A using BareMetal, I strongly suggest you contact Pro-Support services.

Best regards.

Hello Jorge,

thank you for the prompt reply.

About provisioning, since SPT v10 already supports i.MX95, I was inclined to think that more MPU were going to be added in the future. If this is not the case, what kind of support is available from NXP to support fuse management, secure boot and encryption on i.MX91/93? I'd expect an SRM to be available under NDA through distributors, but what about software tools (for example, IMX_CST_TOOL in i.MX6's days) and additional documentation?

Pro-support for bare metal development on i.MX95 is surely an option - we'll consider this possibility. I am quite aware of the difficulties, having worked on Windows CE bootloaders and key kernel components for i.MX6 - but I'm not scared. The problem is usually getting the right documentation.

Best regards,
Stefano
