Hi Edison, If I understand well, the Crypto, SST and Attestation services do not use IPC, so far. Right? Should the SST/Crypto/Attestation services be disabled when IPC is enabled? May the Library and IPC APIs be used simultaneously? What part of TFM is using IPC?

We should be trying to make sure that we continue this effort, as well as to make sure that any efforts to extend the bootloader are done upstream, and not in the TF-M-specific branch. Are you expecting to be running the non-secure CPU before the secure CPU has finished verifying the images? David
