SDK 5.03

Other Parts Discussed in Thread: OMAPL138, AM1808, WL1271

I downloaded SDK 5.03 from here:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/AM1x/latest/index_FDS.html

I installed ti-sdk-am180x-evm-05.03.02.00-Linux-x86-Install.  The directory structure is different than SDK 5.02 (/board-support vs /psp).  The linux and bootloader revisions are the same for 5.02 and 5.03:  03.21.00.04.  Were there any change going from 5.02 to 5.03?  If yes, why are the revisions the same?

    So why didn't the version numbers change?

    I ran a diff of the 5.02 vs 5.03 for U-Boot.  No changes. 

    I also ran a diff for Linux.  Mostly config file changes, and some patches.  It's not clear if the patches were applied to the code, because no .c or .h files have changed.

    The 5.03 release notes only apply to beaglebone, which does not use an OMAPL138/AM1808 CPU.

    Example Apps Supported all AM platforms, Beagle-xM support, fully integrated open source WLAN support with User Interfaces, accelerated cryptography, benchmarks - dhrystone, whetstone, linpack, 3D graphics, Internet Browser, CPU freq scaling, System Info, MemInfo, Task Info, Network Info, PRU support, ARM/Neon based Multimedia including GStreamer & FFMPEG, LMBench, USB benchmark, Suspend/Resume Power Management, Camera support, Display examples
    Tools CCSv5.01, Flash Tool, Pin Mux Utility
    Documentation Quick Start Guide, Software Developer's Guide, software manifests

    Sitara Linux SDK 5.03.02 supports ALL platforms including our new AM335x and Beaglebone and include the following features:

    uboot/SPL 2011.09 (based on mainline uboot)
    xloader n/a (deprecated by new SPL support in uboot)
    kernel 2.6.37, 3.0.8, 3.1

    SDK 5.03.00 was specific to AM335x and Beaglebone (for the official release) before we did SDK 5.03.02 that included support for ALL devices again.  The kernel and bootloaders for AM180x have not changed.  The SDK version is representative of other components & documentation, training etc that have changed from SDK 5.02 to SDK 5.03.02.

    Thanks for the detailed response.  The reason I was waiting for 5.03 is because it was supposed to have a Beta open-source WLAN driver for WL1271 as opposed to the Alpha 2 version in 5.02.  If there were no changes to Linux, is the driver still Alpha 2?  Or was the Alpha 2 driver so good it didn't require any fixes?

    Inderjit,

    The driver definitely changed but I would need to ping the WLAN team to understand what specifically changed in their driver between SDK v5.02 and v5.03.  That said, assuming you have about 9 more days there will be a new SDK v5.04 across AMx devices that will include an updated WLAN driver that provides better performance.

    Not sure how the driver can change if the source code didn't but moving on to 5.04:  will it include bluetooth as well as WiFi for AMx?
