TQMa62xx - YOCTO Linux BSP documentation

Overview

The TQMa62xx which is located on the MBa62xx provides a powerful embedded module platform based on Ti’s Sitara™ 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.

Changelog

Changelog BSPs

Changelog Scarthgap.TQ.ARM.BSP.0004

Added

  • Verified Boot with signed U-Boot, signed FIT image and dm-verity rootfs for

    • TQMa8x
    • TQMa8Xx
    • TQMa8XxS
    • TQMa91xx/TQMa93xx

  • TQMa91xx/TQMa93xx: Add new WKS template with two root partitions and a separate data partition for A/B boot with RAUC updates

    The new partitioning will be selected automatically when "rauc" is enabled in DISTRO_FEATURES. The WIC_ROOTPART_SIZE and `WIC_DATAPART_SIZE variables default to "1G" and "100M", respectively, and can be adjusted as needed.

  • machines:

    • restore support for TQMa6ULxL on MBa6ULxL SBC
    • add new machine for TQMa8MPxL on MBa8MP-RAS314 starter kit
    • add new machine for TQMa91xxCA/LA on MBa91xxCA starter kit

  • u-boot-imx-tq_2024.03: new recipe with support for TQMa91xx and TQMa93xx

  • imx-tq-atf_2.10: support for TQMa91xxCA/LA

  • linux-rt-tq-6.12: add recipe to support PREEMPT_RT with the same branch as used for linux-tq-6.12

  • linux-tq-6.12:

    • support TQMa93xx[CA/LA] on MBa93xxCA / MBa93xxLA / MBa91xxCA
    • support TQMa335x[L] on MBa335x
Changed

  • u-boot-tq-2023-04:

    • TQMa6UL: decrease bootdelay for mfg / uuu defconfigs to 1 sec
    • TQMa6UL: bootcmd is adjusted to start only fastboot gadget for mfg / uuu defconfigs.

  • linux-rt-tq-6.1:

    • backport upstream fixes for TMPDIR leakage
    • integrate changes from linux stable-rt up to tag v6.1.132-rt50
    • rewrite recipe to keep shared settings in include file

  • u-boot-ti-tq-2023.04: allow boot without signed kernel

    • meta-ti does not set UBOOT_SIGN_ENABLE by default anymore, breaking boot with our U-Boot branch. Disable enforcement of signature checks.

      This only has an effect on U-Boot build that do not embed a public key to check a signature against (which is the default now). If UBOOT_SIGN_ENABLE is set, a key will be built into U-Boot and signatures will be verified.
