• 'Pre-built U-Boot binaries in the release package are for DDR3 @800MHz clock'
  

USBx_ID configuration

• The USB0_ID/USB1_ID pin is always configured through software in DM816X silicon revisions. This configuration is done by chosing appropriate configuration through USBx_ID menuconfig selection. more information refers to USB Configuration Page.

Following changes are applicable for release 04.00.01.13 onwards:

• We are migrating from "legacy" mmc driver to a "generic" mmc driver in the latest u-boot .This will break the existing boot script used. Please refer the U-boot user guide and update you scripts according to that.
• When using PCIe boot mode, NAND and/or NOR may not be accessible from U-Boot and kernel. Please refer "Conflict with NAND/NOR and DM814x/DM816x PCIe Boot Mode setting" section in PCI Express Endpoint Boot Driver User Guide
  

• There is a change in the ECC layout in the kernel for 1-bit HW ECC scheme. This change is made to synchronise the ECC layout with Uboot (and make it in accordance with the community). It is advised that the customer must re-flash any data to NAND that was flashed earlier using the previous release kernel.
  -Previous release ECC byte positions: UBoot: [40-51], Kernel: [52-63]
  -Current release ECC byte positions: UBoot: [40-51], Kernel: [40-51]
  

• This release supports both 8 and 16 bit NAND flash. To use 8-bit NAND, set the CS0BW (buswidth) switch on the EVM to ON state. To use 16-bit NAND, set the CS0BW (buswidth) switch on the EVM to OFF state. The switch states for 8 and 16 bit (ON and OFF respectively) are decided so as to maintain backward compatibility with our previous releases which supported 16-bit NAND flash by default (i.e. CS0BW pin in OFF state).

• HDVPSS binaries are no longer packaged with release tar ball, instead they can be downloaded from the PSP Software Download page
  

Following are applicable for PSP 04.00.01.13_patch2 release.

• This release adds support for V4L2 capture driver on top of 04.00.01.13 release. There is no major change in this release apart from addition of V4L2 capture. Please refer to 04.00.01.13 release notes for more details about change between 04.00.01.12 release and 04.00.01.13 release.
• Please note that V4L2 capture driver requires I2C1 instance to be controlled from Linux side. So any of the application/driver trying to access I2C1 from any other processor wont work.
• Only one instance of V4L2 capture driver is supported with TVP7002 decoder

In addition, note following changes applicable for release 04.00.00.09 onwards:

• The kernel in release will not boot with U-Boot from release(s) earlier to 04.00.00.06, unless 'machid' environment variable is set correctly. Please refer "Setting up Machine ID" section form User Guide for more details. .
  

Introduction

This is Release 04.00.02.14 of TI816x Linux PSP tested on DM8168/AM389x EVM. The EVM consists of base board (Rev B/C/D DDR2/DDR3) with daughter card having second Ethernet port and NOR. In the rest of the document, we will refer this setup as DM8168 EVM.

The Linux PSP serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments DM8168 EVM. The Linux kernel and U-Boot software in this release are based on the following open source repositories:

SDOCM00086234	DM81XX: USB: video capture and play from usb camera (creative) is inconsistent for 640X480 resolution
SDOCM00086887	DM81XX: USB: when overcurrent device connected to DM81XX host,VBUS_ERROR occurs further connecting good device does not work
SDOCM00085300	TI816X: u-boot: Second Stage u-boot does not load automatically from SD-Card
SDOCM00082592	TI81XX: ASoC: Audio Capture Noise: The captured file has a lot of noise
SDOCM00082844	TI816X: Sil9022a -Missing TI81xx_un_register_display_panel ()

Known Issues

This section lists known issues observed in this release:

Issue Identifier	Issue Headline	Known Workaround(s)
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.
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.
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)
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.
SDOCM00085072	No SPI software support (including SPI boot) for DM8168 Rev H EVM.	There is no workaround as of now. The SPI part used in this revision of EVM is different from the ones used in the earlier EVMs.
SDOCM00082503	SATA loadble module support: System hang observed when ahci_platform.ko module was unloaded.	None. Requires a system reboot.
SDOCM00085989	DM81xx:V4L2 Capture: FPS is low with capture +fbdev loop back (PSP04.00.01.13_patch2)	None
SDOCM00085993	DM81xx:V4L2 Capture: Kernel dump is seen on starting capture (PSP04.00.01.13_patch2)	None
SDOCM00086261	DM81xx:V4L2 Capture: Filter is always selected for 1080P60 mode (PSP04.00.01.13_patch2)	None
SDOCM00082602	SD removal while I/O is in progress causes system hang	None. It is recommended not to remove the card while I/O is in progress.
SDOCM00087448	USB_Audio : DUT hangs for 8 to 10 sec while unpluging the USB audiodevice during playback	Recommeded to stop the audio playback before unplugging of audio device.
