Read This First

  • 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.
  • 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.

In addition, note following changes applicable for release 04.01.00.02 onwards:

  • The kernel NAND driver uses 1-bit h/w ECC and U-Boot is also updated accordingly. So it is mandatory to re-flash the latest U-Boot along with kernel and filesystem (if using NAND based kernel and/or filesystem) before proceeding to boot the kernel.
  • The serial console device names to be used are changed from 'ttySx' to 'ttyOx'. This means you will need to change the boot arguments passed to kernel and the /etc/inittab file in the filesystem accordingly. Please refer "Using The Correct Console Device" section from User Guide.
  • 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 from User Guide.

Introduction

This is Release 04.01.00.03 of TI814x Linux PSP tested on DM8148 EVM. The EVM 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:

SDOCM00077516 U-Boot does not read MAC address from eFuse registers
SDOCM00077309 SD boot clk config missing
SDOCM00078439 HDMI: HDMI PLL is not kept in bypass before re-programming
SDOCM00078332 HDMI: Display quality is not good with 1080P60 output

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
 None.
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.

SDOCM00072969
Kernel build throws warnings

None.

These warnings will not be fixed as they are from common kernel or Omap OMAP(2/3) source.

SDOCM00072442
NAND 4 bit ECC not supported in TI814x

None.

This is a hardware issue and will not be supported.

SDOCM00074366
Linux SD driver cannot detect SD card hot insertion
Make sure to insert SD card before booting
SDOCM00078276
MMC/SD card's write protect status is not detected
None.
SDOCM00078292
Kernel build fails if IOMMU Debug-FS is enabled in kernel configuration
IOMMU debug-fs should always be built as module
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 other Board.
SDOCM00078905
TILER: Passing less memory to Linux kernel will crash memmanager test suite
Pass 512MB to Linux kernel
SDOCM00078869
USB: TI81XX: rmmod followed by insomd of ti81xx.ko failed
No work around
SDOCM00078870

No workaround
SDOCM00077522
