TQMLX2160A - YOCTO Linux BSP documentation



Overview

The TQMLX2160A which is located on the MBLX2160A provides a powerful embedded module platform based on NXP's Layerscape architecture. 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.

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.

  • doc:

    • Added known issues for TQMa1012AL, TQMLS102xA, TQMLS1028A
    • Added feature matrix for TQMa1012AL, TQMLS102xA
    • various improvements
Fixed

  • TQMa62xx[L]/TQMa64xxL/TQMa67xx[L]: Fix MAC address assignments

    On each of these modules, two addresses more than intended (and reserved for the module) were assigned to ethXaddr variables in U-Boot.

    This issue is a regression in the new U-Boot version added in scarthgap.TQ.ARM.BSP.0005.

  • TQMLS102xA: Enable missing Linux drivers

  • TQMLS10xxA: Fix UBIFS rootfs partition selection

  • linux-tq-6.12: TQMLX2106A: Fix creation of multiple DPAA2 DPSW objects

  • 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
