AM37x SDK 4.0 Release Notes

Release Notes - June 7, 2010


This is Release 4.00 of the AM37x Software Development Kit (SDK). The SDK serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments AM3715. The Linux kernel and U-Boot software in this release are based on the following open source repositories:

Component Version Base Repository Base Tag (or commit id)
OMAP Linux Kernel 2.6.32(Linux kernel version) The baseline was chosen from "pm" branch of;a=shortlog;h=refs/heads/pm 3fd5969a81a9324b58a1c19cf510c0da97c99565. History on "pm" branch gets rewritten and hence the commit may not be valid always.
U-Boot 2009.11;a=summary v2009.11

The filesystem was built from the Arago Project.

The codebase for Linux kernel and U-Boot included in this release is also hosted at the following repositories:

Component Repository (Branch) Baseline Tag Release Tag
OMAP Linux Kernel;a=summary


OMAPPSP_03.00.01.06_baseline v2.6.32_OMAPPSP_03.00.01.06

For detailed information on the various software components included in the release and how to use them, please refer to the AM37x EVM Software Developer's Guide.

The kernel and U-Boot have been compiled with CodeSourcery GNU Toolchain for ARM Processors 2009-q1-203 based on GCC 4.3.3


The AM37x Software Developer's Guide provides instructions on how to use the AM37x SDK. A copy of the AM37x Software Developer's Guide is included in the docs folder of the SDK installation.

To be fixed in future releases
software Pinmux utility requires Left-click to select a peripheral interface cell. The cell should be auto selected when user right-click it. No impact to functionality.  Just a note on the user interface.
To be fixed in future releases
software Matrix GUI can not be controlled from mouse Mouse support is not enabled by default. The AM37x EVM Software Developer's Guide contains information on how to enable this support
To be fixed in future release
software QT browser ignores http_proxy settings. Hence outside urls won't be reachable inside a firewall. Users will not be able to browse URLs outside their firewall
To be fixed in future releases
software Links from Start Dev (i.e. target.html) web page don't work inside a firewall. Users should reference the setup.htm file located in the START _HERE partition on the SD card.
To be fixed in future releases
software Matrix TUI should not be started from /etc/init.d (i.e. /etc/init.d/matrix-tui start).
Users should run matrix_tui by calling matrix_tui directly
