Embedded module TQMa8MPxS - YOCTO Linux BSP documentation

Overview

The TQMa8MPxS which is located on the MB-SMARC-2 provides a powerful embedded module platform based on NXPs i.MX8 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.

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 Scarthgap PRE-Release

Added

  • linux-rt-tq-6.12: TQMLS10xxA / TQMLX2160A:

    Mark recipe as compatible for these machines

  • TQMa8MPxS: add board support for SoM on MB-SMARC-2

  • TQMLX2160A: Add Secure Boot support

    See the TQMLX2160A README for more information. The current implementation only secures the boot process up to the bootloader. The kernel and userspace are not verified.

Changed

  • imx-atf-tq: TQMa8 / TQMa9:

    Include NXP fixes up to tag lf-6.6.52-2.2.1 and adjustments for Layerscape.

  • linux-rt-tq-6.6: TQMa6 / TQMa6UL[L]x[L] / TQMa7 / TQMa8Mx / TQMa8MxML / TQMa8MxNL:

    Include stable fixes up to v6.6.101 and stable-rt fixes up to v6.6.101-rt59

  • linux-tq-6.6: TQMa6 / TQMa6UL[L]x[L] / TQMa7 / TQMa8Mx / TQMa8MxML / TQMa8MxNL:

    Include stable fixes up to v6.6.102

  • linux-imx-tq-6.6: TQMa8 / TQMa9:

    Include NXP fixes up to tag lf-6.6.52-2.2.1 and stable fixes up to 6.6.101 from linux-fslc

  • linux-[rt-]tq-6.12: TQMa335x / TQMa93 / TQMa8MP / TQMLS10xx / TQMLX2160:

    • Include linux-stable fixes up to 6.12.41
    • configure STMMAC as built-in to support NFS root on boards with MDIO on STMMAC

  • machines: use require for machine config includes

  • alsa-state: enable IN3_L / Left Mixer input path (prepare MicIn support) for i.MX base SoM

  • layer.conf: add LAYERRECOMMENDS

Fixed

  • u-boot-tq-2023.04: TQMa6x:

    Add errata workarounds for KSZ9031 ethernet phy to improve reliability of establishing a link.

  • u-boot-tq-2017.11: TQMLS102xA:

    Upstream device tree node naming for ESDHC controller was changes. Fix board specific DSR code to be compatibel with old and new naming.

  • u-boot-imx-tq-2024.04:

    FEC driver MDIO bus handling for enabled DM_MDIO and DM_ETH_PHY has several flaws that were hidden behind ifdefs. The code has fixes for the relevant code paths.

  • u-boot-tq-2023.04: TQMa7x:

    No MDIO bus was found after fixing several bugs in fec-mxc driver. Bug was caused by forcing unique MDIO bus names via device tree. Naming should be handled by FEC driver that creates the bus depending on Kconfig settings.

  • u-boot-lsdk-tq-2019.04: TQMLS1028A: Fix PCIe initialisation flow

    Backport some fixes to the initalisation flow, limit to Gen2 and add wait for link polling. Both the limitation and the polling loop improve compatibility to more cards, since bootloader support is crucial for working PCIe under Linux.

  • tq-bootconf: add reproducible default for 'FIT_CONF_PREFIX'

    When adding support to machines a reproducible default is needed to keep boot configurations and fitImages in sync.

  • TQMLS1012AL: Fix build with Secure Boot support

    Secure Boot on the TQMLS1012AL is build-tested only.

  • qoriq-atf: Fix hash calculation on all Layerscape platforms

    Fixes validation failure when Secure Boot is enabled.

Removed
  • u-boot-tq_2018.07: remove recipe after TQMLS10xxA was upgraded to v2022.04
