Changes in NAND flash

• The default ECC scheme used across Uboot, Kernel and File System is changed to 8-bit BCH ECC.
• The release supports both 8 and 16 bit NAND flash. The settings to select the NAND buswidth, using the CS0BW switch, have changed from the previous release. To use 8-bit NAND, set the CS0BW (buswidth) switch on the EVM to OFF state. To use 16-bit NAND, set the CS0BW (buswidth) switch on the EVM to ON state.
• UBIFS file system support has been enabled by default in the kernel. Since 8-bit BCH ECC scheme is using [2-57] bytes of the 64 byte OOB area in NAND, accommodating metadata for JFFS2 file system can not be supported with 8-bit ECC scheme. Hence, usage of UBIFS file system is recommended.
  

TI814X/3X/1X

• DVFS/CLOCK: A fix for frequency scaling of ARM not working issue( SDCM00089416) is available as a patch over the release package for 04.04.00.01. This can be downloaded from ARM PLL frequency change fix

• OCMC: As a part of pm_init() idle clockdomains are being forced to sleep this applies to ocmc clock domain as well, ocmc clock domain data was added in release 04.04.00.01. If the user wants to use ocmc ram then ocmc interface clock must be enabled using clk_enable(NULL, "ocmc_ram_ick"); before accessing ocmc ram otherwise access to ocmc ram fails.

Introduction

This is Release 04.04.00.01 of TI81xx Linux PSP tested on following devices:

• 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.
• DM8148 EVM. The EVM(Rev B DDR3) consists of base board, catalog application card and LCD adapter board In the rest of the document, we will refer this setup as DM8148 EVM.
• DM813X EVM. The EVM(Rev A DDR3) consists of base board In the rest of the document, we will refer this setup as DM813X EVM.

TI814X

Issue Identifier	Issue Headline	Known Workaround(s)
SDOCM00084561	USB:TI814X: Dynamic detection of USB-ID pin not working on DM814X PG2 when device connected after linux bootup	Use onboard jumper J22/J23 (on TIEVM) to short (for host mode) and open (for device mode) to configure usb-id pin of usb0/usb1.

SDCM00089416 Details(fixed)

Description:
ti814x: PM: DVFS: Arm frequency scaling is not reflected in system performance
Details:
scenario: Test different OPPs using userspace governor of Cpufreq.Observe the impact on system performance and tasks that are being executed
Expected result:When frequency is reduced the cpu time taken by a task must increase.
Observation: Cpu load of a perticular task does not change when switched to a different OPP.
