TQMa91xxLA - YOCTO Linux BSP documentation

This page is work in progress and therefore subject to change

Overview

The TQMa91xxLA provides a powerful embedded module platform based on NXP’s i.MX9 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.

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

Changelog

Changelog BSPs

Changelog PRE-RELEASE

Added

  • 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-tq-6.12: update to v6.12.80
  • linux-tq-6.6: update to v6.6.133
  • linux-rt-tq-6.6: update to v6.6.132-rt72
Fixed

  • u-boot-imx-tq-2024.04:

    • TQMa93xxCA/LA: set thermal trips from fuses

      Using hard settings for consumer grade CPU can lead to boot issues for industrial graded CPU when the temperatur is outside of consumer grade temperatur range.

Removed
  • imx-atf-tq-2.10: remove recipe, all users were updated to use imx-atf-tq-2.12
  • qoriq-atf-2.10: remove recipe, all users were updated to use qoriq-atf-2.12
  • u-boot-tqmt-2015.07: TQMT10xx variants using this recipe are not supported under scarthgap.
  • linux-tqmt-5.15: TQMT10xx variants using this recipe are not supported under scarthgap.
  • machines: Remove TQMT10xx variants since they are not supported under scarthgap.
