MBa93xxLA-Mini - YOCTO Linux BSP documentation

Overview

The TQMa93xxLA on MBa93xxLA-Mini provides a powerful embedded platform based on NXP’s i.MX93 CPU series. The Linux Board Support Package (BSP) is based on the Yocto Project using the ci-meta-tq and consists of a Bootloader (U-Boot), Linux kernel and a minimal RootFS configuration. All BSP sources which are created or customized by TQ are provided via GitHub.

TQ Yocto Layer

meta-tq

meta-tq layer is the TQ hardware support layer, it provides machine configuration, U-Boot and Linux kernel recipe and covers machine specific dependencies to cpu vendor yocto layer.

meta-dumpling

meta-dumpling is supporting layer for meta-tq and part it and provides Yocto image and distro example configurations.

For each Board Support Package (BSP), the corresponding modules are organized 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.

  • 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

Removed

  • linux-ti-tq-6.1

    linux-ti-tq-6.1 has been obsolete since scarthgap.TQ.ARM.BSP.0001 in favor of linux-ti-tq-6.6. With the addition of linux-ti-tq-6.12 as the new default kernel for TQMa62xx[L]/TQMa64xxL/TQMa67xx[L], the linux-ti-tq-6.1 recipe is removed.

  • u-boot-ti-tq-2023.04: remove recipe

    Only u-boot-tq-2025.07 is supported for the TQMa62xx[L], TQMa64xxL and TQMa67xx[L] in future BSP releases.

  • linux-tq-5.4

    • TQMLS102xA is now supported by linux-tq-6.12

  • linux-rt-tq-5.4

    • Currently there is no replacement for RT-enabled kernel on TQMLS102xA
    • Support for newer kernels can be added on request

  • linux-imx-tq-5.15

    • Both TQMLS1012AL and TQMLS10128A are now supported by linux-imx-tq-6.6

  • MBaX4XxL

    • The legacy Image kernel image has been removed from the root filesystem

      We boot the fitImage by default since kirkstone.TQMa64xxL.BSP.SW.0007. U-Boot versions older than that release need to be updated, or a custom BSP image including Image in KERNEL_IMAGETYPES needs to be built.
