Hello everyone, I’m working with the i.MX7ULP, which includes both an Arm® Cortex®-A7 core and an Arm® Cortex®-M4 core. Each of these cores has its own set of OTP SRK hash registers (one set for the M4, one set for the A7).
For simplicity, I’m considering using the same SRK Hash values for both cores. However, I’m not sure if this could lead to any security or boot implications, or if it’s better to keep the SRK sets separate. Could you please share your insights or recommendations?
I’d greatly appreciate any guidance, references to documentation, or examples of best practices regarding this.
Thank you!
