Design proposal: Changing secure service call in library model

by Mate Toth-Pal

Hi All, I'm planning to change the way secure services are called in Library model. The design proposal can be found here: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/2201/ Please note that the changes proposed by this document does not affect the PSA dev API, and does not affect IPC model. Please share your opinion in gerrit comments Thanks, Mate

Regression test - SST - MAX_ASSET_SIZE

by Vikas Katariya

Hi, This would test the interface for NS and S with the set, get and remove with maximum `SST_MAX_ASSET_SIZE` and different sizes for all platforms (including feature-twincpu targets in the near future). It uses a common 4K buffer in total to assist with read and write of asset data. We need to make sure we are able to perform this operation flawlessly on all the targets. Patch Review Request: https://review.trustedfirmware.org/c/trusted-firmware-m/+/2167 https://review.trustedfirmware.org/c/trusted-firmware-m/+/2168 Thanks & Best Regards, Vikas Katariya IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Re: [TF-M] Issues with qspi_ip6514e_set_spi_mode with IAR

by Jamie Fox

Hi Thomas, One way this can happen is if the QSPI driver is being executed in place from QSPI, so the device is never idle because instructions are being fetched from it. On Musca-A, MCUboot is copied to Code SRAM before being executed to avoid this issue. There is some code in the Armclang/GCC scatter/startup files to support this. Is there something similar implemented for the IAR port?

Re: [TF-M] Design proposal for HW crypto key integration in TF-M secure boot

Hi, In case of no further comment on the proposal I'm planning to merge it by Monday. https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1453/ Tamas -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Tamas Ban via TF-M Sent: 24 September 2019 10:22 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Design proposal for HW crypto key integration in TF-M secure boot Hi, The design proposal about the integration of TF-M secure bootloader (MCUBoot) with HW key(s) are close to finalize: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1453/ If you are interested in the topic and have a comment / suggestion then please share it. Tamas From: Tamas Ban Sent: 03 July 2019 17:50 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Design proposal for HW crypto key integration in TF-M secure boot Hi all, PSA Trusted Boot and Firmware Update specification requires the support of at least one immutable root of trust public key (ROTPK) for firmware verification. It is beneficial to be able to provision these keys during the factory life-cycle of the device independently from any software components. The current key handling solution in TF-M secure boot does not supports this key provisioning process. MCUBoot requires compile time built-in public key(s) for image verification. The following design proposal addressing this issue: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1453/ Feel free to add any comments you want on the review!

Re: [TF-M] Please enable -pedantic-errors for gcc builds

by Ken Liu (Arm Technology China)

Hi Thomas, We tried to enable the "-pedantic-errors" flags and finished some fix. Some of them mentioned in your last mail has been pushed, and updated at: https://developer.trustedfirmware.org/T475 The reason we do not enable it as default is that there some sources files from the external project, which causes inconvenience to enable this. Please help to review these patch to see if it is acceptable for the issue for now, after that we could find a chance to merge it. And we can enable this flag internally and create more patches to fix the tf-m native source in future. Thanks. /Ken -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu (Arm Technology China) via TF-M Sent: Saturday, August 17, 2019 5:48 PM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Please enable -pedantic-errors for gcc builds Hi Thomas, This is a very helpful suggestion. Since I am doing some cleanup these days, let me try this option and see how much we need to improve.

T398/T413

by Thomas Törnblom

This is a notification of a patch I pushed yesterday. It consists of standard C source cleanup and initial toolchain support for IAR Embedded Workbench. The target is Musca A and I will provide further support for the psoc6 once the twincpu branch has been merged to master. The Musca A port is not yet fully functional but debugging is in progress.
