DaVinci PSP 03.02 Beta (r35) Release Notes

DaVinci PSP 03.02 Beta Release (Build r35)

Release Notes

April 15, 2010

Introduction

This is the DaVinci PSP 03.02 Beta release (Build r35). The PSP serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments DM6467 and DM6467T EVM. This abstracts the functionality provided by the hardware. The product forms the basis for all application development on this platform. The Linux Kernel in this release is based on the linux-davinci tree, version 2.6.32-rc2. The U-Boot is based on the u-boot.git denx tree, version 2009.08-02958-g3655a31 . The File system is based on the Arago, version 2009.11.

• Follow the instructions to configure OEBASE, SCRATCH and http/git proxies - http://arago-project.org/wiki/index.php/Setting_Up_Build_Environment

• Build Arago base filesystem for dm6467-evm or dm6467t-evm

$ MACHINE=<machine> bitbake arago-base-image

• Build U-Boot and Arago demo filesystem for dm6467-evm or dm6467t-evm; The Kernel for dm6467-evm is automatically built due to the dependency of demo filesystem with the kernel. The Kernel uses the default configuration with all drivers (except Ethernet) built as dynamic modules. The Kernel modules are populated in the demo filesystem

$ MACHINE=<machine> bitbake arago-demo-image

$ For building U-Boot, refer to the instructions TBD

• Build Kernel image for dm6467-evm or dm6467t-evm, using the default configuration with all drivers built as static

$ MACHINE=<machine> bitbake linux-davinci-staging-static

• The images will be available under $HOME/oe/arago-deploy folder

Upgrade and Compatibility Information

Refer to the Migration section of DaVinci PSP 03.02

Host Support

This release has been validated on the following host machines:

• Red Hat Enterprise Linux 4 for Code Sourcery toolchain - 2007q3-51 version
• Windows XP SP2 for CCS v3.3 Installation

Dependencies

The DaVinci PSP release depends on Code Sourcery tool chain and Code Composer Studio (CCS). CCS is needed for initial (or recovery) flashing of UBL and U-Boot (Serial Flash utility is an alternate option without having to use CCS). As long as U-Boot remains functional on the EVM, CCS will not be needed.

Device Support

This release supports the Texas Instruments DM6467 and DM6467T SoCs along with the DM6467 and DM6467T Evaluation Module (EVM).

Validation Information

This release has passed the system test cycle on the following devices

• ARM running at 297MHz and DDR at 297MHz on DM6467 EVMs
• ARM running at 495MHz and DDR at 396MHz on DM6467T EVMs.

Fixed in this release (Beta, Build r35)

• VPIF-Capture: DM6467/DM6467T: console fills up with lot of debug messages when capture starts
• VPIF-Capture: DM6467/DM6467T: Calls to VIDIOC_TRY_FMT and VIDIOC_S_FMT cause kernel oops in some cases
• VPIF-Display: DM6467/DM6467T: Artifacts seen in video played out during demo 720p H264 or MPEG2 decode operations
• VPIF-Display: DM6467/DM6467T: encodedecode demo shows very poor color quality with DM6467T EVM rev C.

Known Issues

USB

• USB ISO Audio and Video are not supported

Video Display

• Video display drivers do not support mmap operation. Only userpointer is supported.
• For User pointer buffer allocation, buf size should not be passed as a part of bootargs

Ethernet

• 10/100M failure is observed intermittently on some DM6467T alpha boards
• 1G is not working with 1G switches on DM6467 Rev G boards.

ATA

• ATA performance will be lower than LSP 2.x as community kernel defaults to UDMA mode 4 instead of UDMA mode 5 for DM6467.

NAND

• NAND performance is lower than DaVinciPSP 03.02.00 alpha release

PCI Host

• Please refer PCI Host known issues for known issues.

PCI Boot

• Please refer here for known issues.

Audio

• Audio playback slows down (sounds stretched) when HD/ED video is played out. This is because of a known issue with the EVM design. In the current EVM, the MCLK input to audio codec and the video is derived out of outputs controlled by the same PLL inside CDCE949. Because of this changing the video clock affects the audio clock leading to slowed down playback.
