Read This First

• This release adds support for V4L2 capture driver on top of 04.01.00.06 release. There is no major change in this release apart from addition of V4L2 capture. Please refer to 04.01.00.05 release notes for more details about change between 04.01.00.05 release and 04.01.00.16 release.
• Please note that V4L2 capture driver requires I2C2 instance to be controlled from Linux side. So any of the application/driver trying to access I2C2 from any other processor wont work.
• Only one instance of V4L2 capture driver is supported with TVP7002 decoder

Introduction

Fixed in this Release

This section lists issues fixed in this release:

Issue Identifier	Issue Headline
SDOCM00085989	DM81xx:V4L2 Capture: FPS is low with capture +fbdev loop back	None
SDOCM00085993	DM81xx:V4L2 Capture: Kernel dump is seen on starting capture	None
SDOCM00085999	DM81xx:V4L2 Capture: Capture driver continously reports "Unable to allocatebuffers"	This happens where capture driver is configured for un-supported values. rmmod ti81xxvin.ko and insmod ti81xxvin.ko
SDOCM00085998	DM81xx:FBDEV: FBDEV driver does not take bpp change effect first time
SDOCM00082716	ti814x: clock: ADPLL's clkout rate is different from what is programmed
SDOCM00082475	USB:TI8XX: Removal of flash drive during file i/o will lead to crash observed from filesystem module
SDOCM00081534	DM81XX: Dual musb controller with one controller(usb0) as host and other controller(usb1) as device feature is not supported
SDOCM00082541	USB:TI8XX: The file i/o to flash drive fails when connected through Full Speed HUB
SDOCM00083827	omap:mtd:nand: unable to boot uboot if it is flashed from kernel
SDOCM00082763	SD: Hang observed on removal and insertion of sd card
SDOCM00082505	TI81XX: NAND module support: Second insmod of nand driver (omap2.ko) fails due to improper cleanup during rmmod

Known Issues

This section lists known issues observed in this release:

Issue Identifier	Issue Headline	Known Workaround(s)
SDOCM00084027	ti814x: clock: clock parent change is not reflected in debugfs	None
SDOCM00084446	ti814x: pm: suspend-resume: DDR should be in self refresh mode before entering suspend	None. In the future releasses, DDR will be put in self-refresh mode during suspend to save power and execution should be done from OCMC
SDOCM00072638	Audio: Overrun, underrun errors observed for less period sizes less than 64 frames	Use period size >64.
SDOCM00072456	Fourth test(try to write off end of device) in mtd_oobtest is failing for read on third mtd partition	This is a limitation in Linux NAND stack. Fourth mtd_oobtest will fail if used in intermediate partitions in a flash device. Hence if mtd4 is used for mtd_oobtest it would succeed.
SDOCM00078276	MMC/SD card's write protect status is not detected. Writes can happen on the SD/MMC card irrespective of whether the write protect switch on the card is on or off.	Known Issue. The signal MMC1_SD_WP is by default not connected to pin AG4. Instead signal UART0_DSRn is connected. So I2C2 on the daughter cards will be lost on using Write Protect functionality.
SDOCM00078292	Kernel build fails if IOMMU Debug-FS is enabled in kernel configuration	Disable iommu debug-fs support during kernel configuration (menuconfig)
SDOCM00078359	CCS based NAND flashing tool can be used only to flash bootloader	This is a limitation mainly due to the different ECC scheme and ECC layouts used for different images. Hence for flashing other images (like linux kernel and filesystem) use u-boot or uart boot mode.
SDOCM00081588	DM81XX:USB: After four times insmod and rmmod of ti81xx.ko in loop causes crash in dma_alloc_free in cppi41dma driver	Remove all the modules in reverse order and insert all modules in right order again.
SDOCM00085331	DM81XX:USB: MUSB_DUAL_ROLE : Host mode is not working for PG1.x under MUSB Dual ROLE	Will be fixed in next release. refer to arago tree for updated patches.
SDOCM00085277	USB_Audio:seeing many warnings while unpluging USB audiodevice and DUT hangs for sometime	Make sure audio play is stopped before removing device.
SDOCM00085229	USB build warnings: Gives out warnings	No workaround.
SDOCM00082356	DebugFS entries for pinmux show incorrect status for pins	DebugFS is currently not supported for DM81xx pinmux. Please refer user guide for details about changing pinmux settings. While the associated register value read from debugfs should still show correct value (only pullup/pulldown decoding is incorrect).
SDOCM00084561	USB:DM814X: Dynamic detection of USB-ID pin not working on DM814X PG2 when device connected after linux bootup	None.
SDOCM00078500	Audio playback cannot start till record is started	This issue is seen when running capture and playback simultaneously after boot-up. If either a capture or a playback operation precedes the simultaneous operation then things work fine. This problem is due to the recent changes in the ASoC framework
SDOCM00082504	McSPI loadable module support broken, second time insmod of McSPI driver fails.	None. Requires a system reboot.
SDOCM00082597	Hyperlinks in the PDF documents in the release package are missing	This is a known issue. The PDF rendering tool in processor wiki removes the hyperlinks while generating PDF documents. Please use the online wiki documents mentioned in Useful Links section (at the end of this release notes)
SDOCM00084751	SATA driver does not support suspend/resume	This support is not available in the current release. Hence when the system switches to low power state and if SATA support is enabled in the kernel then the suspend/resume process will not disable SATA module and PHY. But this will not affect the suspend / resume process.
SDOCM00085007	TI816X ALSA SoC Audio Resume Fails due to I/O error	System resume from PM suspend state Causes the background audio playback to fail due to "aplay: pcm_write:1528: write error: Input/output error". This will not block any Suspend/Resume functionality and the audio play back can be restart after the failure with out any issue .
SDOCM00084809	ti814x: cpsw: PTP time syncronization not happening when connected to Port 2	None.
SDOCM00085341	SATA hotplug support does not work after a unplug during read/write access.	Do not unplug SATA cable during access
SDOCM00085342	SATA devices cannot be configured to work in PIO mode using the hdparm tool	None. Only option is to use DMA mode.
SDOCM00085204	Nand 4-bit ECC is not working in both kernel and uboot	We plan to support UBIFS for DM814x.
SDOCM00085425	SATA read/write issues due to internal 20MHz clock	The internal 20MHz clock source for SATA PLL has some issues. This is being used as the default clock for SATA. Hence we were seeing interface fatal errors. This is a hardware issue. The workaround is to either use the 100MHz external clock from PCIe or find a 20mhz clock source on the board and feed into XI/CLKIN. The later option is transparent and does not require code change but the former requires code change and the PCIe PLL has to be programmed for this.
