What's New

We continue to enhance the features providing in the Sitara SDK.  This version includes the following new features:

  • Updated U-Boot to version v2012.10.
  • Minor kernel changes.
  • Migrated to OE-Core based build system.

Note - Some applications are platform specific and highlighted in the Software Developer's Guide.

Installation and Usage

The Software Developer's Guide provides instructions on how to setup up your Linux development environment, install the SDK and start your development.  It also includes User's Guides for various Example Applications and Code Composer Studio.

Host Support

The Sitara SDK is developed, built and verified on Ubuntu 10.04 LTS.  In addition to the Long Term Support provided by Ubuntu on this version, we also recommend use of Ubuntu 10.04 LTS to ensure efforts to resolve any issues are not host related.  Details on how to create a virtual machine to load Ubuntu 10.04 LTS are described in the Software Developer's Guide.


Versions prior to 05.02 used the Codesourcery Lite 2009q1-203 toolchain.  This required pre-installation of the cs-lite toolchain before the SDK could be installed.  Versions after 05.02 utilize the open source gcc4.X toolchain and are fully integrated in the Sitara SDK (linux-devkit) no longer requiring a toolchain installation.  SDK version 05.02 supplies gcc 4.3.3. SDK version 05.03 supplies 4.5.3.  SDK version 05.04 and later supplied 4.5.3 with dynamic libgcc and libstdc++ libraries.

Known Issues

The table below lists the known issues in this release. You should check this site periodically for workarounds/solutions to the known issues as they become available.

  1. Sitara board port git trees have not been updated as of December 21, 2012 to use the latest PSP U-Boot and kernel from this SDK release. The update will be made in January.
  2. When booting from NFS on AM335x devices (beaglebone, EVM, EVM-SK) you may see messages like DHCP/BOOTP: Ignoring delayed packet when using some routers. This has currently been observed with some Linksys and Trendnet routers. The result of this issue is that the NFS boot will not succeed.
    The user can add a parameter to the bootargs to give a longer timeout to allow for the DHCP server to respond. This parameter is:


         Setting the value to 200 will double the timeout length and works in most cases. i.e.


ARM_MPU.KERNEL.39 Critical Other SDK 05.03.02+ ALL USB DMA disabled Devices which use the Mentor MUSB core currently disable the DMA due to instability issues. This will cause degradation from the expected USB throughput performance. The DMA support can be enabled in the kernel depending on your use case. The most commonly affected use cases are when the USB core is being used in host mode and there is both DMA and PIO traffic occurring at the same time. This has been observed with many USB WiFi adapters as well as when doing I/O operations to one device which inserting or removing another device. If you choose to enable DMA you should extensively test your use case to verify that no lockup occurs.t
ARM_MPU_SDK.BTS_MATRIX.122 Critical Other SDK05.04.00+ AM37x, AM335x PRCM Suspend/resume does not work completely with touchscreen as a wake-up source This issue was previously noted under Suspend/resume power demo description in MatrixGUI.
ARM_MPU_SDK.BTS_WLAN.33 Critical Kernel SDK 05.05.00 AM335x Wake on Wireless LAN does not work WoWLAN is not working on the EVM SK 1.2B. When using WLAN as a wakeup source a firmware panic is seen even when using UART to wake up the board.
ARM_MPU_SDK.BTS_WLAN.30 Critical Kernel SDK 05.05.00 AM335x WiFi-Direct Demo gui does not function correctly when rootfs is in nfs See Summary
ARM_MPU_SDK.BTS_WLAN.28 Critical Kernel SDK 05.05.00 AM335x Delay before BT keyboard work with HID test When running the HID test in the bluetooth gui a delay is seen between when the test is started and when key presses are recognized. This does not occur with command line testing. The delay can be up to 2 minutes with the bluetooth gui.
ARM_MPU_SDK.Installer_Scripts.63 Critical Kernel SDK 05.05.00 All if the SDK path doesn't have the last '/', the script throw Invalid SDK path Add the / when specifying the path to work around this issue
ARM_MPU_SDK.BTS_MATRIX.93 Critical Kernel SDK 05.05.00 AM335x Multimedia demo Mepg4+AAC dec has noise in audio. The system is running out of resources during the decode operation of both audio and video which can lead to the audio noise heard.
ARM_MPU_SDK.BTS_Documentation.47 Not Critical Other SDK 05.05.00 AM335x u-boot source tree for board port does not build for release The board port u-boot tree for release found in the SDK does not build properly. This has been updated and fixed in the git repository at
ARM_MPU_SDK.BTS_MATRIX.140 Not Critical Cryptos/Security SDK 05.05.00 AM335x openssl server cannot be accesses from external device When running the openssl server demo the server cannot be accessed from an external device. Messages like the following are seen:

A PKCS #11 module returned CKR_DEVICE_ERROR, indicating that a problem has occurred with the token or slot.

(Error code: sec_error_pkcs11_device_error)

ARM_MPU_SDK.BTS_KERNEL.79 Critical Kernel SDK 05.05.00 AM335x ifdown/ifup eth0 interface in dual cpmac mode and with ping traffic This is filed as issue SDOCM00094019 in the PSP kernel
ARM_MPU_SDK.BTS_KERNEL. Critical Kernel SDK 05.05.00 AM335x Multicast packets are not received when in dual cpmac mode When in switch mode, SK target is able to receive multicast packets.

When kernel is built with dual_cpmac option, these packets are not received.

ARM_MPU_SDK.BTL_WLAN.20 Critical WiFi SDK 05.04.00+ All Leaving Bluetooth demo running for an hour causes a stale list of devices and stale pairing information Leaving the demo running can result in a stale scan list such that pressing the "start scan" button will fail to find new devices. Restarting the demo will allow finding the new devices, but devices that were previously paired need to be re-paired.
ARM_MPU_SDK.BTS_BENCHMARKS.5 Not Critical Boot Time SDK 05.02+ All Boot stalls at gnome-vfs During the first boot of a clean file system the boot will stall for a while at the "Configuring gnome-vfs" step. Depending on the SD card speed or network speed this could be a couple of seconds or could take a minute. During this time the gnome-vfs package is doing a large amount of read operations and not all SD cards are read optimized. On subsequent boots this is not required and should no longer cause a delay. Scenarios where this might be encountered are when making a new NFS or SD card file system from the SDK pre-built file system found in the filesystem directory.
ARM_MPU_SDK.BTS_MATRIX.135 Not Critical Other SDK 05.04.00+ All When booting from NFS the /etc/resolv.conf file is not populated When booting from NFS the user space udhcpc command is not run since the root file system is using the network. This prevents the /etc/resolv.conf file from being populated by the DHCP server which can lead to not being able to browse to web sites such as Updating the contents of /etc/resolv.conf and rebooting will configure the network to allow the DNS lookup to occur.
ARM_MPU_SDK.BTS_Make.18 Not Critical Makefiles SDK 05.04.00+ All top-level SDK Makefile matrix-gui target fails install The top-level Makefile in the SDK directory will fail the "make matrix-gui_install" target since the file no longer exists.
ARM_MPU_SDK.BTS_CCSV5.16 Not Critical Other SDK 05.04.00+ All QT projects report error during build When building projects like qt-tstat in CCSv5 an error is reported while processing the .pro file. The project builds successfully and this error can be ignored.
ARM_MPU_SDK.BENCHMARKS.7 Not Critical ARM SDK 05.03.02+ ALL Dhrystone results may vary Dhystone may vary from the expected 1.8 DMIPS/MHz. Increasing the number of iterations that dhrystone runs will decrease the variability of the results.
ARM_MPU_SDK.FLASH_TOOL.7 Not Critical Other SDK 05.03.02+ BeagleBone, AM335x no flash tool support Flashing may be done using u-boot: AM335 Flash Programming Guide
ARM_MPU_SDK. INSTALLER_SCRIPTS.50 Not Critical Other SDK 05.03.02+ ALL script cannot save oldbootcmd from default u-boot params because of string length. After running to create a minicom script, when you run the mincom script, you may see a "setenv usage" message.  The oldbootcmd will not be saved.  The result of this is that you may lose your intial bootcmd after you run the script. (NOTE) you can get back to default u-boot enviroment by doing a nand erase of the u-boot parameters partition in NAND.
ARM_MPU_SDK. INSTALLER_SCRIPTS.25 Not Critical Other SDK 05.03.02+ ALL script may display two IP addresses as default option. Type the IP address of the Linux host instead of taking the default.
ARM_MPU.ExApps.25 Not Critical Other SDK 05.03.02+ AM335x Oprofile -when running a session you can see quite a few 'rm' errors When running an NFS mounted file system, and running the Oprofile Applications, "Run Signal Parent" and "Run Signal Parent Optimized" you see many can not "rm" errors. This is just an annoyance the rm is successful. This issue will be resolved in the next release.
ARM_MPU_SDK.BTS_MATRIX.136 Not Critical Other SDK05.03+ All 3D demos could not run when running NFS When rebuilding the kernel and installing the kernel modules, the existing modules are removed by the modules_install step of the kernel build. For out-of-tree driver modules such as the SGX modules this requires that those modules be re-built against the re-built kernel. Not rebuilding and re-installing these modules to the target file system will result in the applications that use those drivers, such as the 3D demos to fail to run.
