TQMa95xxLA - YOCTO Linux BSP documentation

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.

Documentation and Downloads

TQ Systems provides comprehensive documentation on its embedded mini-module products to facilitate the evaluation and design phase with our products.

The following documents can be downloaded directly from our Website (no login required) for the desired product:

User Manual (Baseboard)
Detailed hardware descriptions, installation steps, jumper settings, connector layouts and troubleshooting tips.
User Manual (Module)
Electrical specifications, interface overviews, software setup guides and reference tables.
Datasheets
Absolute maximum ratings, timing diagrams and ordering information.

The Customer Info Archive is provided upon purchase of a Starter Kit and is released on request by TQ Support. To obtain it, please open a Support Ticket with your order details.

The archive includes:

  • Mainboard schematic & placement diagram
  • Module CAD files (native format)
  • Module mechanical dimensions (2D/3D drawings)
  • Pinmuxing configuration (recommended device tree fragments)
  • Pinout reference (signal assignments, voltage domains)
  • Design checklist (layout guidelines, EMI/ESD considerations)
  • Processing instructions (LGA Modules)

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.
tq-systems/meta-tq/blob/<git-tag>/meta-tq/doc/README.SoftwareVersions.md

Changelog BSPs

Changelog PRE-RELEASE

Added

  • u-boot-2026.01: add TQMa62xx and TQMa64xxL 1GiB Nanya RAM variants

  • imx-atf-tq: add support for v2.12 based on NXP lf_v2.12 branch

  • qoriq-atf: add support for v2.12 based on NXP lf_v2.12 branch

    Add support for TQMLS1012AL, TQMLS10xxA, TQMLS1028A, TQMLX2160A

Changed
  • linux-rt-tq-6.12: incorporate TQ-Systems fixes from linux-tq-6.12
