DaVinci PSP 03.01 Phase 3 Release (Build r28)

Release Notes

November 24, 2009

Introduction

This is the DaVinci PSP 03.01 Phase 3 release (Build r28). 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 2.6.32-rc1. 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.

Fixed in this release (Phase 3, Build r28)

• SPI: DM355: EVM hangs during bootup, when SPI driver operation mode is set to interrupt mode; This release fixes the issue of interrupt mode (PIO mode of operation), and also supports DMA mode of operation
• Video capture(V4L2): Cannot switch between the formats - NTSC/PAL (at run time, from Linux). This release fixes the issue in the TVP514x decoder driver
• Video display (fbdev): The boot parameters for fbdev display are not mapped correctly in the video driver
• Video display (fbdev): The fbset command hangs when the console is on (which by default on)
• Video display (V4L2): V4l2 display hangs during loopback in MMAP mode
• Video display (V4l2): Display driver displays the previous queued frame in place of current queued frame
• RTC, Keyscan: RTC and Keyscan drivers could not be insmod'ed, after they are built as modules
• USB ISO Video: DM355/DM365: WebCam does not get enumerated properly, when plugged in, after unit has booted up. There seems to be an issue with Microsoft webcam drivers. Logitech webcam seems to work fine.

Fixed in this release (Phase 2, Build r26)

• 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; A delay was required before starting the ECC correction

• NAND (JFFS2) on DM365: Intemittent kernel failure is observed during NAND read/write test; The problem is not reproducible after the linux-davinci staging tree was rebased to Kernel version 2.6.32-rc1

• 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; The issue is fixed in the musb driver

• USB ISO: Audio class does not work; This was due to setup related issues with USB ISO Audio.

• NAND ECC test failed when using uImage built from Arago; but it pass when using uImage built on the cloned kernel. After moving to 2009q1 CodeSourcery toolchain the issue is not reproducible

• NAND: After lots of write/read, read operation becomes slow and 'ls' becomes really slow even after umount and reboot.

• NAND: First nand read in uboot return failed message; but the second nand read in uboot works fine

• U-Boot: There is a limitation in the length of the uboot environment variables.

Known Issues

• Audio: DM355: Gstreamer fails with a lot of underruns with audio. The same configuration using arecord/aplay does not give any underrun with audio; Gstreamer works fine on DM365
  • Workaround: None

• Audio: DM355: ALSA read failed when sample rate is 96000Hz
  • Workaround: None

• Audio: DM365: Default volume for DM365 is low
  • Workaround: Use amixer sset commands to increase the volume level on the capture and playback sides.

• GPIO: DM355: 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 (fbdev): fbdev display driver fails to allocate coherent memory for 1080i resolution (set via bootargs)
  • Workaround: If most of the other drivers are built as module, fbdev driver can allocate coherent memory for 1080i resolution.

• 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

• Resizer: DM355/DM365: Resizing any resolution to SD resolution have a lot of noise in the display in continuous mode. Resizing operation on YUV stream in continuous mode have intermittent noises
  • Workaround: None

• 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 Slave: USB Slave MSC Performance under GIT release is lower than the LSP release (2.10, 2.6.18 based)
  • Workaround: None

• NAND/MTD: 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

• NAND/MTD/JFFS2: '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/MTD/JFFS2: NAND performance in r28 (2.6.32-rc1) is worse than previous build (2.6.31-rc7) for all platforms including dm365. This seems to be a JFFS2 issue, NAND raw performance is consistent across the builds
  • Workaround: Moving to a stable 2.6.32 version can help

• EMAC: DM365: Ethernet performance under GIT release is lower than the LSP release (2.10, 2.6.18 based) when using Iperf.
  • Workaround: None

• DM9000 Ethernet: DM355: 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

• MMC/SD: DM365: MMC/SD slot 1 (bottom slot on the EVM) has problems. The following cards could not be detected: Kingston SDHC (4GB), SD (2GB, 1GB), DANE-ELEC SD (1GB), TRANSCEND MMC (2GB) and Sandisk MMC (1GB)
  • Workaround: None

• MMC/SD: DM355/DM365: When the MMC or SD card is unplugged while mmcblock device mounted, the device hangs and device cannot not recover even after plugging back the card
  • Workaround: None

• SPI: Performance under GIT release is lower than LSP release (2.10, 2.6.18 based); This is due to the raw EEPROM driver in the open-source kernel (Misc driver), as against the MTD driver in LSP 2.10.
  • Workaround: None
