TF-A on iMX8M Mini

by Iñigo Vicente Waliño

Hi, I am using an iMX8M mini, I have flashed the image with uuu.auto of L4.14.98_2.0.0_ga_images_MX8MMEVK and I have a Linux image with OP-TEE. Now I want to use TF-A but I don't know the steps to continue. I am reading this document ( https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/gui… and https : //trustedfirmware-a.readthedocs.io/en/latest/plat/imx8m.html <https://trustedfirmware-a.readthedocs.io/en/latest/plat/imx8m.html>) but I don't know how to get these files: u-boot.bin, u-boot-nodtb.bin, u-boot-spl.bin , DTB U-Boot file (for example, fsl-imx8mq-evk.dtb). Can anyone tell me the steps to follow? Thanks, best regards Iñigo.

FIP header flags available for feature selection

by Scott Branden

Hello, The fip header has reserved fields available for platform specific use. The fiptool allows these header fields to be filled in using the --plat-toc-flags. A call needs to be available in the ATF framework to get these flags without accessing the FIP file again to get these flags. We have a solution we've used for ATF for quite some time to access these flags. It's finally being upstreamed here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/2839 If there are any other efficient methods to access these flags or a better proposal please suggest. Thanks, Scott

Re: [TF-A] Issue with addition of NXP Platform support on TFA v2.2

by Olivier Deprez

Hi Pankaj, Can you pls provide a bit more background: Which boot stage (BL1/BL2/BL31...) get affected? Is there any crash report to console? Is this an aarch64/or aarch32 platform? There can be different root causes to this e.g. 1. a stale translation in TLB, or a dirty cache line remnant from earlier boot stages. If this is the case, it would need invalidating TLB and/or caches on BL entry. 2. the empty table ptr given by xlat_table_get_empty is pointing nowhere sensible because of this specific platform layout There are multiple calls to xlat_clean_dcache_range in this file, do you confirm the crash happen within xlat_tables_map_region? Can you try one or both statements below after the call to xlat_table_get_empty (and uncomment calls to clean_dcache_range): inv_dcache_range((uintptr_t)subtable, XLAT_TABLE_SIZE); xlat_arch_tlbi_va((uintptr_t)subtable, ctx->xlat_regime); xlat_arch_tlbi_va_sync(); Regards, Olivier. -----Original Message----- From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> On Behalf Of Pankaj Gupta via TF-A Sent: 05 February 2020 11:45 To: tf-a(a)lists.trustedfirmware.org Subject: [TF-A] Issue with addition of NXP Platform support on TFA v2.2 Hi, In the TFA v2.2 code base, the file "lib/xlat_tables_v2/xlat_tables_core.c" has the implementation for function "xlat_tables_map_region()".

CI status update - end to end boot testing on Juno

by Fathi Boudra

Hi, The end-to-end testing prototype is now completed and enabled. This encompases an end-to-end testing pipeline whereby TF-A code submission to gerrit results in a TF build (based on the code submission) being injected into a file system (recovery image) and booted on a Juno device in the Linaro TF LAVA instance with the results of the boot test available in the LAVA instance. Here's the explanation of the CI pipeline: 1. Trigger - capture gerrit events: https://ci.trustedfirmware.org/job/trigger-tf-a-builder/ All changes made to the trusted-firmware A repository are captured by the trigger event and result in a build. e.g., triggering commit: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3100 Note: this is in silent mode (links to the build job are currently disabled, and will be re-enableb today). 2. Build Binary Artifacts - Binary artifacts built via: https://ci.trustedfirmware.org/job/tf-a-builder/ e.g., https://ci.trustedfirmware.org/job/tf-a-builder/631/ (with a link to the accompanying LAVA job and a link to the trigger job in gerrit) 3. Recovery/Flash submission to LAVA - Used to flash the binary to the board: https://ci.trustedfirmware.org/job/post-build-lava/ 4. LAVA tests results e.g., Specific example of the template applied to a specific build (631 above) https://tf.validation.linaro.org/scheduler/job/895/definition Results: https://tf.validation.linaro.org/results/895 Link to all jobs: https://tf.validation.linaro.org/scheduler/alljobs Some additional information: * tf-a-ci-scripts git repository has been set up and contains the CI scripts for TF-A. https://git.trustedfirmware.org/ci/tf-a-ci-scripts.git/ * tf-a-job-configs git repository has been set up and contains the Jenkins jobs configurations automatically deployed on https://ci.trustedfirmware.org Jenkins instance. https://git.trustedfirmware.org/ci/tf-a-job-configs.git/ Cheers, -- Fathi Boudra Linaro.org | Open source software for ARM SoCs

Issue with addition of NXP Platform support on TFA v2.2

Hi, In the TFA v2.2 code base, the file "lib/xlat_tables_v2/xlat_tables_core.c" has the implementation for function "xlat_tables_map_region()".

Due to this addition, my earlier* working platform on TFAv1.5, is hanging here. If the function call for the function "xlat_clean_dcache_range()", is comment, then the platform works well.
