Re: [TF-M] [RFC] TF-M Documentation Contribution Format

by Gyorgy Szing

Hi, I think this effort should be done together with other tf.org projects using the same technology (Sphinx). Can you pls sync up with the TF-A team? Related to the details: * I suggest referring to the RTD style guide [1] instead of Python. The text is much smaller, does not cover topics we don’t need and your points 1-5 are aligned. Point 6 is conflicting as RTD allows 6 levels. * I disagree on 11. “A drawing is worth 1e3 words”, and hiding these at the end is not a good practice. * 12: do we really need this? How often are people doing such things? * 13 is ok 😊 * 14: might be too strict. What if a term is over used and may have a different meaning is some sections (i.e. platform, host, etc...). [1] https://documentation-style-guide-sphinx.readthedocs.io/en/latest/style-gui… /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Minos Galanakis via TF-M Sent: 30 June 2020 16:23 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] [RFC] TF-M Documentation Contribution Format Hi, As the project matures, and the community grows, I would like to revive an old discussion and suggest that we set some guidelines for contributing to the project's documentation. I would like to propose that we establish a minimal sub-set of rules, based on the official Python guidelines<https://devguide.python.org/documenting/#style-guide> which is the most widely used notation. This offers compatibility with existing tools for proofing and producing said documentation. The following rules should be considered: 1. H1 document title headers should be expressed by # with over-line (rows on top and bottom) of the text 2. Only ONE H1 header should allowed per document, ideally placed on top of the page. 3. H2 headers should be expressed by * with over-line 4. H2 header's text should be UNIQUE in per document basis 5. H3 headers should be expressed by a row of '=' 6. H4 headers should be expressed by a row of '-' 7. H3 and H4 headers have no limitation about naming. They can have similar names on the same document, as long as they have different parents. 8. H5 headers should be expressed by a row of '^' 9. H5 headers will be rendered in document body but not in menus on the navigation bar. 10. Do not use more than 5 level of heading 11. When writing guide, which are expected to be able to be readable by command line tools, it would be best practice to add long complicated tables, and UML diagrams in the bottom of the page and using internal references(auto-label). Please refer to the `tfm_sw_requirement.rst<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/docs/getti…>` as an example 12. No special formatting should be allowed in Headers ( code, underline, strike-through etc ) 13. Long URLs and external references should be placed at the bottom of the page and referenced in the body of the document 14. New introduced terms and abbreviations should be added to Glossary and directly linked by the `:term:` notation across all documents using it. When something new, which is not covered is required, the rule should be first to follow the any reference to of an existing document, and the Python Documentation rules otherwise. Please let me know if you have any questions/objection or proposals or new rules you would like to consider. Any feedback is more than welcome. Minos

CORE_TEST and the new build system

by Christopher Brand

It seems that docs/reference/services/core_test_services_integration_guide.rst hasn't been updated to reflect the new build system (it says to build using ConfigCoreTest.cmake). That config isn't mentioned in docs/getting_started/tfm_build_instruction.rst. So how do I build the CORE_TEST stuff with the new build system (I'm particularly interested in the IRQ test). Thanks, Chris Brand Sr Prin Software Engr, MCD: WIRELESS Cypress Semiconductor Corp.

Musca-B1 and new build system

by Raymond Ngun

Hi all, I am attempting to build Musca-B1 with the latest in master but I'm not able to get it to run (nothing shows on the UART). At a minimum, the User Guide is out of date in terms of how the final hex is created. So, I have a couple questions. 1. Is the latest tested with Musca-B1? 2. Can I obtain some updated information on how to build and create an image for Musca-B1? Thank you, Ray This message and any attachments may contain confidential information from Cypress or its subsidiaries.

Re: [TF-M] Removal of MCUboot fork from TF-M

by Adrian Shaw

This is excellent work and great news for both projects. Well done. Best, Adrian ________________________________ From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> on behalf of Tamas Ban via TF-M <tf-m(a)lists.trustedfirmware.org> Sent: 30 September 2020 11:13 To: tf-m(a)lists.trustedfirmware.org <tf-m(a)lists.trustedfirmware.org> Cc: nd <nd(a)arm.com> Subject: [TF-M] Removal of MCUboot fork from TF-M Hi, In the last few quarter TF-M team have worked on actively to upstream the TF-M related features from the forked MCUboot repo to the original repository. This activity has been finished recently and as a result the MCUboot fork has been removed from TF-M repo. Currently TF-M exclusively relies on MCUboot project as a secure bootloader. From now on all new development will be directly contributed to the upstream repo. List of feature which were upstreamed: * HW rollback protection * HW key integration * Data exchange between MCUboot and runtime firmware * RAM_LOAD boot mode * DIRECT_XIP boot mode BR, Tamas Ban

Using TF-M through ymodem to download tfm_s_enc_sign.bin---------STM32L562

by 徐鹏

Hello Jaouen, I have a development issue when running TFM download process on the STM32L562.Print a error log"[ERR] Image in the secondary slot is not valid!" when download tfm_s_enc_sign.bin.ALL other 3 bin（tfm_s_sign.bin，tfm_ns_sign.bin，tfm_ns_enc_sign.bin） download success. I follow the document UM2671 chapter 11.4 Download a new firmware image. The project is en.stm32cubel5_v1-3-0.zip，file：Projects\STM32L562E-DK\Applications\TFM Steps to reproduce: 1.run Projects\STM32L562E-DK\Applications\TFM\TFM_SBSFU_Boot\MDK-ARM\regression.bat to init device 2.build TFM_SBSFU_Boot application，TFM_Appli secure application，TFM_Appli non-secure application，Build TFM_Loader application 3.run Projects\STM32L562E-DK\Applications\TFM\TFM_SBSFU_Boot\MDK-ARM\TFM_UPDATE.bat to programing into STM32L5 internal and external Flash memory 4.success to run into app 5.press user button (blue) during board reset, the user enters local loader menu. 6.use ymodem to download tfm_s_enc_sign.bin to secure image 7.reset and then print error log "[ERR] Image in the secondary slot is not valid!"

Re: [TF-M] [RFC] The code review guideline

by Ken Liu

Hi, I would merge this one as it has been put there review for a while, thanks all the reviewers. This would provide a basic shape while we are creating new features, also could be viewed better after rendered. There would be many points can be updated later, let’s try to use it and see how it works – Create issues at https://developer.trustedfirmware.org/ and assign to me if there are, reply here is also workable. Thanks. /Ken From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: Tuesday, September 1, 2020 9:50 AM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] [RFC] The code review guideline Hi, We are creating one document to describe the code review guidelines: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5372 The goal of this document is to introduce the source management level concepts to be followed while reviewing a code – which try to simplify the contribution (but burdens the reviewers? 😉). Difference to the `coding style`: * It focuses more on the source placement, interface definition and including, etc. As this document is keeping evolving in a period, the plan is we merge a simple version as start and adding more contents by new patches, so please give enough comments if you have, and don’t forget the concept: we want to make things rational and simple. Thanks. /Ken
