DaVinci PSP 03.01 Phase 1 Release Notes

DaVinci PSP 03.01 Phase 1 Release (Build r20)

Release Notes

August 27, 2009

Introduction

This is the DaVinci PSP 03.01 Phase 1 release (Build r20). The PSP serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments DM355 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 2.6.31-rc5. The U-Boot is based on the u-boot.git denx tree, version 2009.06-rc0. The File system is based on the Arago, version 2009.09.

Upgrade and Compatibility Information

Refer to the Migration section of DaVinci PSP 03.01 Linux Installation User Guide

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 DM365 and DM355 SoCs along with the DM365 and DM355 Evaluation Module (EVM).

Validation Information

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

• ARM running at 296MHz and DDR at 243MHz on DM365 EVMs
• ARM running at 216MHz and DDR at 171MHz on DM355 EVMs.

Known Issues

• NAND ECC on DM365: Only the error bits introduced in first 512byte chunk get corrected and other 512byte chunks of the page do not get corrected
  • Workaround: None
• NAND (JFFS2) on DM365: Intemittent kernel failure is observed during NAND read/write test
  • Workaround: None
• Audio: Gstreamer fails with a lot of underruns with audio. The same configuration using arecord/aplay does not give any underrun with audio
  • Workaround: None
• GPIO: bank interrupt and non-bank interrupt can not work in the same time. This is a limitation in the driver implementation
  • Workaround:If the driver is configured for bank interrupts (default), all GPIOs can be used in the interrupt mode
• Video display tears when running the loopback in user pointer mode
  • Workaround: Use the 'fbdev_loopback_nomemcpy' application from the examples. The video tearing issue was the side effect of memcpy in the application
• Video display (fbdev): Cannot switch betwween the formats - NTSC/PAL (at run time, from Linux)
  • Workaround: The video formats can be changed from the bootargs in U-Boot
• Video raw capture: Micron sensor capture fails when used at a resolution 1080P or more in MMAP mode when video driver is loaded dynamically. Micron sensor capture also fails at maximum resolution in MMAP mode. There is also a kernel crash, when the Micron sensor capture application is run with bufsize set to QXGA resolution
  • Workaround: Use the Micron sensor capture in userpointer mode, since maximum resolution with userpointer mode works fine
• Video raw capture: Micron sensor capture cannot achieve the required frames per second (60 fps, for progressive capture), getting only 16 fps. This is found to be limitation with the design of Micron sensor driver
• IPIPE: When built as a module, the IPIPE driver crashes during insmod operation
  • Workaround: IPIPE driver can be built in to the kernel as static
• USB OTG: When the USB Host, Slave drivers are built as modules and the driver is configured to be in OTG mode, removing the module gives a kernel panic
  • Workaround: USB driver in OTG mode can be built in to the kernel as static
• USB OTG: OTG fails the USB-Forum Test suite on both high-speed and full-speed modes
  • Workaround: None
• USB MSC: The performance with this release is lower than the LSP release (2.10, 2.6.18 based); With this release the Host MSC read performance is 9.4MBps and write is 0.72MBps, while with the LSP 2.10 release Host MSC read performance is 11.4MBps and write is 0.84MBps.
  • Workaround: None
• USB ISO: Video class does not work; Video camera gets enumerated but the camera capture does not work. It gives an error about STREAM_ON ioctl. The video camera does not get enumerated properly, when plugged in, after unit has booted up.
  • Workaround: None
• USB ISO: Audio class does not work
  • Workaround: None
• NAND ECC test failed when using uImage built from Arago; but it pass when using uImage built on the cloned kernel.
  • Workaround: If the kernel is built standalone (not within Arago environment), ECC correction works fine
• Flash_eraseall option -j is not working; The issue is due to the 4K support. It required a parameter in the mtd-abi structure to be updated which broke the IOCTL flash_eraseall -j option was calling.
  • Workaround: None
• 'sync' command or 'umount' command are really slow for first write which results in kernel dump. This seems to be an expected behavior, since the filesystem commands seem to cache the data in RAM before writing to NAND devices
  • Workaround: None
• NAND: After lots of write/read, read operation becomes slow and 'ls' becomes really slow even after umount and reboot.
  • Workaround: None
• NAND: First nand read in uboot return failed message; but the second nand read in uboot works fine
  • Workaround: Always do a partial nand read first and then do the full nand read
• U-Boot: There is a limitation in the length of the uboot environment variables.
  • Workaround: The lengthy values can be split into multiple variables and then these variables can be merged
• DM9000 Ethernet: Performance with this release is lower than the LSP release (2.10, 2.6.18 based); With this release the TCP performance is 22.3Mbps while with the LSP 2.10 release the TCP performance is 25.5Mbps.
  • Workaround: None
