Hi everyone
I wanted to make it easier to debug HardFaults/BusFaults/SecureFaults in TFM, since I've gotten quite a few of them while adding the nrf platforms.
I have created a proposal in https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7891 and would like to get some comments on the general idea.
The proposal gathers a number of different values, especially the ones that are harder to retrieve in a debugger, like the fault status registers in SCB.
The values are placed in memory so they can be inspected in a debugger, and if built with -DTFM_SPM_LOG_LEVEL=TFM_SPM_LOG_LEVEL_DEBUG they are also printed.
Here is an example of the printout:
FATAL ERROR: HardFault
Here is some context for the exception:
EXC_RETURN (LR): 0xFFFFFFBD
Exception came from non-secure FW in thread mode.

Hi,
Just a humble suggestion: capability could be added to cmake to generate a build environment manifest. This could be a JSON or simple text file listing the location and version of each dependency (tool or software). The manifest file could simplify tracking down similar issues.

Subject: Re: [TF-M] Is Musca-A deprecated already?
Thanks Sherry,
Appears the current "cysecuretools" has a dependency on imgtool 1.7.0a1, which is likely where it came from.
I did build for musca_a last week and I may have updated cysecuretools since then as I had issues with flashing the psoc64, and that must have installed 1.7.0a1.
I installed 1.7.1, which caused a dependency error on cysecuretools 3.0.0.
Works now!
Cheers,
Thomas

Hi Thomas,
The issue is caused by the imgtool package itself. The version 1.7.0a1 is a pre-release version. If you check the line 378 of image.py of the imgtool package of version 1.7.0a1, it does not check the 'None' before accessing the custom_tlvs.items:
[cid:image003.jpg@01D6F552.951E90A0]
In the version of 1.7.1, it has added the 'None' check at line 389 in image.py:
[cid:image004.jpg@01D6F552.951E90A0]
In TF-M build system, the custom_tlvs should be 'None'.
To solve your issue, I suggest you use a release version of the imgtool package, such as 1.7.1, other than a pre-release one.
Please let me know how it goes.
Regards,
Sherry Zhang

Hi Thomas,
Can you share the version of the imgtool package you used? The recommended version is >=1.6.0. We run the build command on Linux locally and it works well.
An alternative option is to use the imgtool script from the upstream MCUBoot repo. To achieve that you can copy the folder ./build_dir/lib/ext/mcuboot-src/scripts/imgtool to bl2/ext/mcuboot/scripts/wrapper/.

I'm working on some IAR brokenness for the cypress/psoc64 and for comparison I'm attempting to build for my favorite board, the musca_a, but it seems builds fails now. I think it was working last week, but today I'm unable to build with any of the toolchains.
I get the following errors frmo all of them. Here's a gcc build:

Hi Thomas,
I can also confirm that the build works on a system with the linked environment<https://review.trustedfirmware.org/plugins/gitiles/ci/dockerfiles/+/refs/he…> setup.
I have tested your command, as well as the two methods listed in the documentation and all appear to be working.
Given this opportunity I would like to share that in accordance to the TrustedFirmware.org project maintenance proposal<https://developer.trustedfirmware.org/w/collaboration/project-maintenance-p…>, the project should not be removing a platform in without fair notice. In TF-M we try to do so in three steps between releases:
* Adding a deprecation warning patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6516> which will notify the users during compilation and runtime.
* Marking is as soon to be deprecated in documentation.
* Removing the files on or after the marked release.
Back to your problem, I would also confirm that there are no environment variables setting a pre-downloaded repository for TF-M tests.
Please let us know how it goes.
Minos

Hi all,
Per the off-line discussion with Andrew, I’d like to start a wider discussion on the interrupt APIs, specifically the Secure Partition API changes for interrupt control in chapter 6.3.3.
There are the following APIs:
* uint32_t psa_irq_is_enabled (psa_signal_t irq_signal);
This API returns 0 if the interrupt is disabled and 1 if the interrupt is enabled.
* psa_irq_status_t psa_irq_disable(psa_signal_t irq_signal);
This API returns the status of the interrupt prior to this call with an implementation defined value
Note the return type of the interrupt status is different.
The first one is only to tell whether the interrupt is enabled (1) or not (0) – an equivalent to bool type.
The second one could be any value to indicate an interrupt status. And that value is intended to be passed to psa_irq_restore to write to the interrupt control register directly.
* void psa_irq_restore(psa_signal_t irq_signal, psa_irq_status_t saved_status);
The typical usage:
psa_irq_status irq2_state = psa_irq_disable(IRQ2_SIGNAL) ;
// manipulate data shared with IRQ2 …
psa_irq_restore(IRQ2_SIGNAL, irq2_state);
This is a very efficient design as the 'saved status value' can be the exact value that needs to be written to an interrupt control register to restore the previous state.
But TF-M seems to be unable to take that advantage.
Because the most common interrupt controller is the NVIC provided by the core.
The NVIC takes 1/0 to enable or disable the interrupt and one register for 32 interrupts.
The underlying NVIC operation provided by CMSIS is NVIC_Enable/DisableIRQ.
So the psa_irq_status_t in TF-M would simply 1 or 0 for a specific interrupt signal.
Then the psa_irq_restore could be unnecessary if psa_irq_disable returns uint32_t just like psa_irq_is_enabled:
uint32_t irq_status = psa_irq_disable(IRQ);
... // critical section
if (irq_status)
psa_irq_enable(IRQ);
Any thoughts on the necessity of the psa_irq_restore API?
The draft implementation of the current APIs for easy understanding:

Subject: [TF-M] Arm Firmware Framework for M 1.1 Extensions Alpha specification
Hi all,
The PSA Firmware Framework for M 1.1 Extensions specification is now published on Arm Developer.
This document introduces a set of updates and extensions to the Arm® Platform Security Architecture Firmware Framework (FF-M) specification, designed to build on the capabilities provided in version 1.0.
This is an initial ALPHA release in order to enable wider review and feedback on the changes proposed to be included in the v1.1 specification. At this quality level, the changes and interfaces defined are not stable enough for product development. When the proposed extensions are sufficiently stable to be classed as Beta, they will be integrated into the FF-M version 1.1 specification.
The 1.1 Extensions document can be downloaded from:
https://developer.arm.com/documentation/aes0039/latest
Both the 1.0 Specification and the 1.1 Extensions document are linked from the main PSA architecture page:
https://developer.arm.com/architectures/security-architectures/platform-sec…
Ken and I have presented a number of times at last year's Tech Forums on the proposals in the specification, most recently I provided a summary of the whole document on 10th December 2020.
If you have any feedback, please provide it to arm.psa-feedback(a)arm.com<mailto:arm.psa-feedback@arm.com>, or discuss the proposals here in the TF-M mailing list.
Regards,
Andrew

Hi,
As mentioned in Tech Forum, call for feedbacks for doxygen usage:
- Anyone is checking doxygen documents?
- Which API are you checking with doxygen documents? The service APIs, or even some internal static API for SPM?
- When you are reading code, will you check the docs or you just open them in editors and then read it?
The background is we put many efforts on docs, it costs effort to maintain the doxygen format comments for all sources even the concept is covered in the docs folder, we are trying to find a balance to help mitigate the effort spent on internal logics (such as those static APIs inside SPM fewer people would update). For the interfaces API, doxygen would be always there so user can find them easily.
Thanks
/Ken
Hi everyone,
The design proposal of adding secure Flash support in TF-M has been
updated, I would like to ask for a review, any comments and suggestions
will be appreciated.

Hi Anton,
I would like to raise a discussion about doxygen usage.
I think it is acceptable to apply doxygen usage in interfaces only if we want to keep alignment with CMSIS code since it applied doxygen result as reference manual; but for other logics, the doxygen is almost not used. Wondered how many users would generate reference manual from doxygen; or they just open an editor then start reading code from sources.
Thanks.
/Ken

Hi Anton,
I would like to propose some changes to the openCI job coverage, it may take ~20 mins.
