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

  • SBOM: allow CycloneDX SBOM generation for Layerscape / i.MX ARM64 boot images

    Conditionally add populate_cyclonedx task to the recipes that construct the boot images. Since these images may be deployed separately a dedicated SBOM is needed.

Changed

  • linux-tq-6.12: update to v6.12.116

  • linux-imx-tq-6.6: update from FSLC, includes stable fixes up to 6.6.161

  • linux-rt-tq-6.6: update to v6.6.159-rt82

  • linux-tq-6.6: update to v6.6.160

  • qoriq-atf-2.12: remove superfluous dependencies

  • imx-boot-tq: set INHIBIT_DEFAULT_DEPS to prevent superfluous dependencies

  • U-Boot / Linux: improve SRCREV handling in .scmversion / localversion

    Support building with EXTERNALSRC with invalid/unknown SRCREV values. For Linux recipes a QA error will be generated if both SRCREV and SRCREV_machine are set.

  • linux-tq-6.12: update to v6.12.103

  • linux-tq-6.6: update to v6.6.151

  • linux-rt-tq-6.6: update to v6.6.147-rt77

  • linux-imx-tq-6.6: update from linux-fslc incl. v6.6.157

Fixed

  • imx-sc-firmware-tq-1.15.0: update to TQMa8.NXP-v1.15.0.B5624.0038 adding backport fixes

    • TQMa8QM: fix PMIC power up ramp time. The calculated ramp time is too large and cause decreased performance when using DVFS
    • TQMa8QM / TQMa8Xx[S]: implement KS1 errata workarounds. The workarounds proposed by NXP shall decrease the current needed when using power management.

  • u-boot-imx-tq-2024.04: allow external RMII REF_CLK for i.MX91 / i.MX93 EQOS

    • backport platform specific reset for i.MX93
    • handle 'snps,rmii_refclk_ext' property in low level chip specific setup handler

  • u-boot-imx-tq-2024.04: backport fixes from upstream for i.MX LPUART

    • use ipg clk for i.MX7ULP compatible variants. This allows to use the same clock properties as in upstream and allows using different UART for console without device tree patching
    • error handling to prevent hang in recieve path
Removed
  • meta-tq/conf/layer.conf: Remove stale LICENSE_PATH
