Read This First

1) The kernel NAND driver now uses 1-bit h/w ECC and U-Boot is also updated accordingly (release 04.01.00.02 onwards). So it is mandatory to re-flash the latest U-Boot along with kernel and filesystem (if using NAND based kernel and/or filesystem) as provided in this release before proceeding to boot the 04.01.00.05 kernel.

2) The serial console device names in this kernel are changed from ttySx to ttyOx (release 04.01.00.02 onwards). This means you will need to change the boot arguments passed to kernel and the /etc/inittab file in the filesystem accordingly when booting the 04.01.00.05 kernel. Please refer Using The Correct Console Device section in User Guide.

3) You might need to update the DHCP script in your filesystem when using network mounted root filesystem with the kernel from this release. Please refer Updating the DHCP Script section in User Guide.

4) The parameter passed to mkfs.jffs2 while creating JFFS2 image has changed, please refer "Creating JFFS2 File-system" section under "U-Boot NAND Support" in U-Boot User Guide.

5) The steps for flashing jffs2 image to NAND from U-Boot has changed, please refer "Flashing File-system from U-Boot" section under "U-Boot NAND Support" in U-Boot User Guide.

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

Introduction

This is Release 04.01.00.05 of TI814x Linux PSP tested on DM8148 EVM. The EVM(Rev B DDR3) consists of base board. In the rest of the document, we will refer this setup as DM8148 EVM.

The Linux PSP serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments DM8148 EVM. The Linux kernel and U-Boot software in this release are based on the following open source repositories:

Fixed in this Release

This section lists issues fixed in this release:

Issue Identifier
Issue Headline
SDOCM00081445 FBDev: reshuffle any fb nodes to SDVENC failed
SDOCM00078931 VPSS UserGuide: Bootargs metioned in vpss user guide are wrong
SDOCM00080165 VPSS: CURRENT_VPS_FIRMWARE_VERSION is not updated correctly
SDOCM00081718 FBDev: blending, color key does not work without calling FBIOPUT_VSCREENINFO
SDOCM00082301 FBDev: stenciling feature not working - mmap stenciling buffer return MMAP_FAILED
SDOCM00082268 FBDev: FBDev module failed to support 1366x768@60 resolution
SDOCM00082170 VPSS: Missing sysfs entry to configure the polarity of DE(ACT VID), HS, VS and FID
SDOCM00074366
Linux SD driver cannot detect SD card hot insertion
SDOCM00075294
Low performace for MMC/SD reads and writes
SDOCM00081566

Nand partition with bad block could not be mounted. Flash_eraseall return errors.

File system was reported to not mount on a Nand partition having bad blocks.

SDOCM00081789
Kernel crashes if the client driver tries to allocate a channel for the cross bar event.
SDOCM00078716

MMC/SD card's write protect status is not acknowledged if a daughter card is attached to the base board.

The MMC/SD card always mounted in read-only mode if a daughter card was connected to the base-board. So, no write operations could be performed on the card.

SDOCM00080155
U-Boot DMM LISA settings do not match the ones in GEL file
SDOCM00079569
SATA warning/error messages observed when kernel boots even when SATA device is not connected

New in this Release

  • NAND 1-bit h/w ECC support in U-Boot and Kernel (Enabled by default)
  • SD card hot insertion
  • Watchdog Timer
  • GPIO
  • PCIe Booting with 32-bit mode (from DM816x RC only)
  • Clock framework
  • Mux framework
  • Support for LCD on Catalog Daughter Card

Known Issues

This section lists known issues observed in this release:

Issue Identifier
Issue Headline
Known Workaround(s)
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.

Write 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.

SDOCM00077875
Host does not enumerate devices connected to all the ports of a port multiplier.
Do not use 0th Port of the port multiplier and connect the required devices to the remaining ports of the port multiplier
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 JTAG flashing tool can be used only to flash bootloader
For other images use u-boot or uart boot mode.
SDOCM00078546
HDMI PLL doesn't get locked on some of Centaurus boards. Will be fixed in PG2.0 version of Silicon
Try on a PG2.x EVM.
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.
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).
SDOCM00082475
USB:TI8XX: Removal of flash drive during file i/o will lead to crash observed from filesystem module
unmount (umount) the flash drive before removing the flash drive from usb port. Again when the flash drive is inserted umount default mount path (/media/sda1) and mount again.
SDOCM00081534
DM81XX: Dual musb controller with one controller(usb0) as host and other controller(usb1) as device feature is not supported
This feature currently not supported.
SDOCM00082541
USB:TI8XX: The file i/o to flash drive fails when connected through Full Speed HUB Use high speed hub.
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
SDOCM00082699 VPSS: System crashes when re-enabling the display after removing external video encoder After external video encoder is removed, do not disable and re-enable the display via /sys/devices/platform/vpss/display#/enaabled, this leads to system crash, patch is available to fix this.
SDOCM00082505
NAND module support: Second insmod of nand driver (omap2.ko) fails due to improper cleanup during rmmod

The requested memory region was not released in driver cleanup function.

The bug has been fixed. The patch fixing the bug will be pushed to arago.

SDOCM00082602
SD removal while IO is in progress causes system hang
The bug has been fixed. The patch fixing the bug will be pushed to arago.
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)
