Hi Gyorgy, Yes, it looks that this is the issue. I saw exactly this behavior when optimization was set to -O1. Do you think, that ARM will prepare official fix of this file? Moreover, when I tried to set optimization to -Os, the regression tests have stopped working at TFM_SST_TEST_1XXX test suite. But I did not try to find the reason why, therefore I cannot say more.

Re: [TF-M] Platform: Create platform service for pin functions

by Miklos Balint

Michel, I agree there is a need for a more generic design pattern for such platform-specific features. I think that there should be a single entry point for any platform specific service request to the platform/ directory and each platform should/could list the specific features it supports. Then the specific function type would be encoded in an invec to the service request. But I think a more detailed design proposal is needed with enough room for discussion before committing to a new pattern, and I'd prefer to avoid introducing platform dependencies in the services/ folder. That folder should ideally just have an indirection across HAL to a platform-specific service request arbiter. Any opinions or should I produce a more detailed proposal to show what I mean?

Re: [TF-M] psa_invec type mismatch in tfm_psa_call_veneer?

by Ken Liu (Arm Technology China)

Hi Both, The intention of doing this is for packing parameters while handling non-secure psa_call(). This function has five parameters, which means the 5th one needs to be put in NS stack. If we extract 5th parameter in veneer function we need to enable non-secure memory accessing for veneer and implement some assembler code there to fetch PSP_NS. To make it simple at first stage we just pack 'psa_invec' and 'psa_outvec' as two inputs of tfm_psa_call_veneer(); that why the two types are invec -- because they really are inputs. This part really causes confuse and need to be discussed if we need to implement more proper way for this.

Hi Alan, I think you're right, the prototypes of these functions should be fixed.

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

by Michel JAOUEN

For the platform without hardware for NV counter, but having trusted memory It is mentioned that the support is possible as follow : "an active image and related manifest data is stored in trusted memory then the included security counter cannot be compromised." the impact for this implementation in mcu-boot is limited to : * The test of the version (security counter is ih_ver from mcuboot header) * The placement of active image and related manifest data in a trusted memory. Is my understanding correct ? As the placement of full image in a trusted memory is a constraint. Can we limit the information placed in a trusted memory to : * image header, * TLV sections. This seems sufficient to support anti roll back. Of course additional impact on mcu-boot must be planned but as multi image support is also targeted , the placement of all images in a trusted memory is likely to be unachievable for all configurations.

Re: [TF-M] build of NSPE with flag __ARM_FEATURE_CMSE=3

by Gyorgy Szing

Hi Michel, Apologies, somehow my response yesterday got lost, so here it goes again: I re-read the documentation and the way you use this macro seems to be valid when targeting v8-M based chips. I see two solutions for your problem: 1. I created a ticket to remove the --mcmse compile flag for non-secure projects. See: https://developer.trustedfirmware.org/T304 After this is fixed, your current code will work as expected. 2. Currently TF-M uses the __DOMAIN_NS macro to define the target domain for the source-code. It is an option to change your code to use this macro. I suggest going for this option if your code is not v8-M specific, and may need to support other architectures in the future. /George -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Antonio De Angelis via TF-M Sent: 03 April 2019 17:40 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] build of NSPE with flag __ARM_FEATURE_CMSE=3 Hi Michel, A ticket has been raised by Gyorgy to track this: https://developer.trustedfirmware.org/T304 Thanks, Antonio -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Michel JAOUEN via TF-M Sent: 03 April 2019 03:03 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] build of NSPE with flag __ARM_FEATURE_CMSE=3 Hello, The flag is defined to __ARM_FEATURE_CMSE == 3U.

Re: [TF-M] build with GNUARM with option -Os

by DeMars, Alan

I had a similar problem. Upon advice in this email list, I fixed it by changing the implementation of "tfm_core_ns_ipc_request()" in secure_fw/core/tfm_psa_api_client.c. Add 'volatile' to the declaration of these variables: struct tfm_sfn_req_s desc, *desc_ptr = &desc; change to: volatile struct tfm_sfn_req_s desc, *desc_ptr = &desc; After this change, I am able to build and run with -O3 as well as -Os. I don't know why this fix hasn't been added to the master branch as this problem has already been identified.

Re: [TF-M] PSA Test Suite forum?

Hi Antonio, Ok, so the TFM is using the old API. Hope, it will be updated soon. I prefer do not downgrade the test suite from master, as it contains >50 of new commits.
