March 2019 - TF-M - lists.trustedfirmware.org

by Andrej Butok

Hello, I have noticed, that with adding the IPC feature to master branch, it were updated GCC linker files (#ifdef TFM_PSA_API sections), but ARMCLANG linker files are without any change. Does it mean that IPC was developed and tested only using GCC? Is there a plan to updated the armclang linker files? Thanks, Andrej Butok

Re: [TF-M] [RFC] twin cpu bootloader design document

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
