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

[Core Patch] Core: switch signal wait object to 'condition'

by Ken Liu (Arm Technology China)

Hi, I will update the wait object from 'event' to 'condition'. This is mainly for fixing the issue: https://developer.trustedfirmware.org/T273 'event' is actually a depth 1 semaphore, which is not good enough for signals synching case. Involve a simpler sync object 'condition' for signals (and client ACKs): https://review.trustedfirmware.org/c/trusted-firmware-m/+/712 Please help to check if you are interested in it. Thanks -Ken

by Ken Liu (Arm Technology China)

Hi TF-M Subscribers, The branch 'feature-ipc' is going to be merged into 'master', and here is the patch: https://review.trustedfirmware.org/c/trusted-firmware-m/+/677 After the merging, the IPC feature will be available in the 'master' branch, future updates on the IPC part will happen in 'master' branch, too. For those patches pushed towards 'feature-ipc' will be reviewed and we suggest push new patchset to 'master' branch. Please reply to this thread without hesitation if there are any questions.

Re: [TF-M] Trusted boot - rollback protection

This section should use "increase" and "decrease" not "increment" and "decrement". There is no requirement that the counter only be incremented (having 1 added to the value), only that it be set to a larger value than the current value. You should probably also add a discussion as to how testing will be done with a HW security counter. Again, my suggestion is to not add an additional counter, but just use the existing version field (minus the build number) as the security counter value. David
