TQMa93xxLA - YOCTO Linux BSP documentation

Overview

The TQMa93xxLA provides a powerful embedded module platform based on NXP’s i.MX 9 CPU series. The BSP is based on the Yocto Project using TQ’s meta-tq hardware support layer, with build host setup instructions and BSP sources provided via GitHub.

Please see the meta-tq repository on GitHub for further instructions. A list of supported Yocto images and example configurations is available in the BSP repository GitHub.

For each Board Support Package (BSP), the corresponding modules are versioned under the matching Git tag in our GitHub repository. Simply check out the tag that matches your BSP release, then open the module’s README file in the “doc” folder to find detailed information.

BSP Tagging and Revisioning

BSP Git Tagging and Revisioning

TQ manages all Board Support Package (BSP) releases in the meta-tq GitHub repository using annotated Git tags. This ensures each release is traceable to an exact source snapshot and clearly documents which Yocto branch, platform (module) and software revision it covers.

Tag Format:
<YoctoBranch>.<ModuleIdentifier>.TQ.ARM.BSP.<RevisionNumber>

Component Description
YoctoBranch Name of the Yocto Project release (e.g. kirkstone, scarthgap)
ModuleIdentifier Target module name when present; omitted entirely for “scarthgap” tags
TQ.ARM.BSP Literal marker for “Board Support Package – Software”
RevisionNumber Four-digit, zero-padded incrementing counter (e.g. 0001, 0002, …)

Examples:
kirkstone.TQMa64xxL.BSP.SW.0008
scarthgap.BSP.SW.0001 – here no module identifier is used

Supported Platforms Reference:
To see exactly which platforms (machines/boards) each BSP tag covers, open the meta-tq folder in that tag and view its README.md:
/tq-systems/meta-tq/tree/<git-tag>/meta-tq
Click on README.md there to find the full list of Yocto machine names, board variants, RAM options and support status.

Changelog

Changelog BSPs

Scarthgap.TQ.ARM.BSP.0004

Added

  • Verified Boot with signed U-Boot, signed FIT image and dm-verity rootfs for

    • TQMa8x
    • TQMa8Xx
    • TQMa8XxS
    • TQMa91xx/TQMa93xx

  • TQMa91xx/TQMa93xx: Add new WKS template with two root partitions and a separate data partition for A/B boot with RAUC updates

    The new partitioning will be selected automatically when "rauc" is enabled in DISTRO_FEATURES. The WIC_ROOTPART_SIZE and `WIC_DATAPART_SIZE variables default to "1G" and "100M", respectively, and can be adjusted as needed.

  • machines:

    • restore support for TQMa6ULxL on MBa6ULxL SBC
    • add new machine for TQMa8MPxL on MBa8MP-RAS314 starter kit
    • add new machine for TQMa91xxCA/LA on MBa91xxCA starter kit

  • u-boot-imx-tq_2024.03: new recipe with support for TQMa91xx and TQMa93xx

  • imx-tq-atf_2.10: support for TQMa91xxCA/LA

  • linux-rt-tq-6.12: add recipe to support PREEMPT_RT with the same branch as used for linux-tq-6.12

  • linux-tq-6.12:

    • support TQMa93xx[CA/LA] on MBa93xxCA / MBa93xxLA / MBa91xxCA
    • support TQMa335x[L] on MBa335x
Changed

  • u-boot-tq-2023-04:

    • TQMa6UL: decrease bootdelay for mfg / uuu defconfigs to 1 sec

  • u-boot-ti-tq-2023.04: allow boot without signed kernel

    • meta-ti does not set UBOOT_SIGN_ENABLE by default anymore, breaking boot with our U-Boot branch. Disable enforcement of signature checks.

      This only has an effect on U-Boot build that do not embed a public key to check a signature against (which is the default now). If UBOOT_SIGN_ENABLE is set, a key will be built into U-Boot and signatures will be verified.

  • linux-tq-6.12: new kernel based on linux-stable kernel

    • support TQMa8MPxL on MBa8MPxL incl. DisplayPort

  • Secure Boot support for TQMa8x and TQMa8Xx

  • TQMa62xx/TQMa64xxL: Add new WKS template with two root partitions and a separate data partition for A/B boot with RAUC updates

    The new partitioning will be selected automatically when "rauc" is enabled in DISTRO_FEATURES. The WIC_ROOTPART_SIZE and `WIC_DATAPART_SIZE variables default to "1G" and "100M", respectively, and can be adjusted as needed.

  • u-boot-*-env: Provide separate fw_env.config variants for different boot media on TQMa62xx/TQMa64xxL (u-boot-ti-tq-2023.04)

  • tq-bootscripts: Provide new boot-blockdev-rauc boot script for A/B boot with RAUC updates On platforms with Distroboot support (TQMa62xx/TQMa64xxL) the new script will be installed automatically instead of boot-blockdev when "rauc" is enabled in DISTRO_FEATURES.

  • u-boot-tq-2023.04: new default bootloader based on upstream U-Boot. With the update the default environment was completely reworked to use canonical variable names compatible with distro boot etc. Kernel and devicetree are expected in rootfs. This adds also support for U-Boot environment access from Linux OS. Additionally, SDP support is added.

    • support for TQMa6ULx
    • support for TQMa6ULxL
    • support for TQMa6ULLx

    • support for TQMa8MxML
    • support for TQMa8MxNL
    • support for TQMa8MPxL
Changed

  • linux[-ti,-imx,-lsdk,-rt,]-tq recipes: improve local version generation. Upstream poky kernel classes change usage of .scmversion files and start using KERNEL_LOCALVERSION. To keep reproducible version string CONFIG_LOCALVERSION_AUTO will be forcibly disabled.

  • example keys and certificates for AHAB are changed to prepare Secure Boot for TQMa8x and TQMa8Xx

  • u-boot-imx-tq-[2020.04,2023.04]: use generic overrides for secure boot The recipe for imx-boot-tq uses nxp-hab4 and nxp-ahab. These are added by machine config. Use them for consistency.

  • imx-boot-tq: adjust to i.MX9 target split in imx-mkimage lf-6.6.36_2.1.0

  • imx-mkimage-tq: update to use NXP lf-6.6.36_2.1.0 code base

  • linux-ti-tq-6.6: Enable DMVerity kernel module

    Used for integrity checking of RAUC bundles in verity format.

  • tq-bootscripts: Do not add temporary variables to the U-Boot environment

  • u-boot-*-env: Do not leave any enabled configurations in the default/fallback fw_env.config

    If no hardware-specific configuration exists, accessing the environment is not supported out-of-the-box. Avoid shipping an incorrect configuration that might write to the wrong MTD partition on fw_setenv.

  • imx-atf-tq-2.10: prepare support for TQMa91xx

  • tqma62xx / tqma64xx: require arch-armv8a.inc to allow more specific tuning.

  • tqmls10xxa.inc: require arch-armv8a.inc to allow more specific tuning.

Fixed

  • u-boot-tq_2023.04: fix a warning in MTD partition parsing when the last partition uses remaining size but free space is left before this partition.

  • u-boot-imx-tq_2020.04 / u-boot-imx-tq_2023.04 / u-boot-tq_2023.04: provide configurations for U-Boot env tools based on rootfs. Multiconfiguration config file does not work in on device in the configuration is not present.

  • TQMa8M: fix U-Boot compatibility to generated signed images.

    Please note that images generated with imx-mkimage version before lf-6.1.55_2.2.0 are not compatible with newer images and vice versa. Image generation and U-Boot has to be updated in lock step.

Removed
  • u-boot-imx-tq_2016.03: recipe is removed since no SoM uses it anymore.
