TQMa95xxLA - YOCTO Linux BSP documentation

Overview

The TQMa95xxLA provides a robust embedded module platform powered by NXP's i.MX 95 processor family. 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.

Get Notified

Enable Notifications:
In order to be automatically notified of new BSP releases by e-mail, you must activate notifications in the corresponding Github repository.

1. Go to the desired repository in Github (e.g. meta-tq)
2. Click on the notification button in the top right corner.
3. Log in or create a Github account if you have not already done so.
4. Select “All activity” so that you will be notified of every new release.

Software Versions:
For the exact versions of U-Boot, Linux kernel and other components used in a BSP tag, view doc/README.SoftwareVersions.md in that tag.

Changelog PRE-RELEASE

Added

  • u-boot-tq-2026.01: new recipe

    Replaces u-boot-tq-2025.10 for TQMa62xx[L]/TQMa64xxL/TQMa67xx[L].

  • TQMa95xxLA: add board support for MBa95xxCA

    This adds the board support based on the same recipe versions used for TQMa95xxSA

  • u-boot-imx-tq-2024.04:

    • TQMa91xx / TQMa93xx: inline ECC support
    • TQMa91xx: 512 MiB RAM configuration
    • TQMa8MPxL / TQMa8MPxS / TQMa91xx / TQMa93xx: distro boot as default
    • TQMa8MPxL / TQMa8MPxS / TQMa91xx / TQMa93xx: distro boot support for SPI-NOR

  • u-boot-tq-2025.10: new recipe (supports TQMa62xx[L]/TQMa64xxL/TQMa67xx[L])

  • TQMa91xxCA / TQMa91xxCA: add board support for MBa93xxCA

    board support is available with imx / nxp flavour only and uses linux-imx-tq-6.6

  • TQMa95xxSA: add board support for MB-SMARC-2

    This adds new versions for u-boot-imx-tq (based on NXP lf_v2025.04) and linux-imx-tq (based on NXP + FSLC 6.12-2.0.x-imx)

  • TQMa93xxLA: add board support for MBa93xxLA-MINI

    board support is available with mainline flavour only and uses linux-tq-6.12

  • TQMa93xxCA / TQMa93xxLA: enable LVDS for mainline linux-kernel on MBa93xxCA and MBa93xxLA

  • Build fitImage kernels by default

    KERNEL_IMAGETYPES now contains fitImage by default on all platforms. Note that the fitImage has not been tested on all machines yet.

  • Introduce KERNEL_IMAGETYPES_INSTALL

    KERNEL_IMAGETYPES_INSTALL can be used to select a subset of KERNEL_IMAGETYPES to install to the target images. By default, all images except for vmlinux are installed, unless "tiny" is listed in DISTRO_FEATURES. With the "tiny" distro feature, only the primary image defined via KERNEL_IMAGETYPE is installed.

  • linux-rt-tq-6.12: TQMLS102xA / TQMa335x:

    Update to branch containing all fixes from stable-rt. Mark recipe as compatible for these machines.

  • MicIn support for all platforms

    • Depending on the used hardware codec control adjustments might be necessary
Changed

  • u-boot-imx-tq-2025.04:

    • TQMa95xxLA: FlexSPI boot support

  • imx-boot-tq:

    • i.MX9[4,5]: do not build FlexSPI boot images for Octal SPI with DTR and DQS by default

      Not all boards have Octal SPI assembled. Use generic but slower setup by default. If needed this can be configured per board using modified QSPI_HEADER environment.

    • update to use upstream version lf-6.12.49-2.2.0

  • linux-imx-tq-6.12: TQMa95xxLA:

    • FlexSPI support
    • 10GiGE support
    • dual LVDS example

  • linux-tq-6.6: update to 6.6.127

  • linux-rt-tq-6.6-rt: update to v6.6.126-rt68

  • linux-tq-6.12: update to v6.12.73

Fixed

  • u-boot-imx-tq-2025.04:

    • TQMa95xxLA: correct FlexSPI pin muxing

      Muxing uses wrong pads. Thus FlexSPI could not be used.

Removed
  • u-boot-tq-2025.10: TQMa62xx[L]/TQMa64xxL/TQMa67xx[L] use u-boot-tq-2026.01 now
