Fixed in this Release

Issue Identifier	Issue headline
SDOCM00067004	VPIF: Modular build fails.
SDOCM00075224	In UBL, 4-bit ECC correction false completion state reported by ECC hardware has been taken care.
SDOCM00075933	DM365: UBL: Removed extended wait configuration for NAND
SDOCM00076092	dm365: Corrected a bug where U-Boot was writing a wring value to teardown EMAC
SDOCM00079458	spi: SPI was unable to transfer > 64KB data using DMA mode. This has been corrected.

Known Issues

Issue Identifier	Issue headline	Known Workaround(s)
SDOCM00059997 (OMAP-L138)	amixer controls to control left/right playback volume is inverted	None. This has to be corrected in the EVM hardware.
SDOCM00060000 (OMAP-L138)	amixer controls to switch on/off, left/right playback is inverted	None. This has to be corrected in the EVM hardware.
SDOCM00060007 (OMAP-L138)	GLCD flickering is observed whenever SPI flash is accessed. This is due to the muxing of GLCD backlight control pins (EPWM) and SPI flash chip select pins	None. This has to be corrected in the EVM hardware.
SDOCM00062443	Unable to create jffs2 partion on nand using flash_eraseall -j	flash_eraseall can be used without -j option and the partition can still be mounted with jffs2 file system.
SDOCM00064559	audio: Capture fails in mmap mode with -v option	None
SDOCM00067005	SPI: CPU load is high even in DMA mode	None
SDOCM00067843 (OMAP-L138)	DA850: When TPS65070 PMIC is configured for an output voltage of 1.0V, I2C bus becomes un-unsable	This is an issue with EVM hardware. It is likely that the errors seen were a result of a hardware buffer on the I2C clock. To workaround this issue, the release uses gpio based bit-banging i2c driver in Linux kernel.
SDOCM00081114 (DM36x)	DM36x: NAND: Raw read/write performance is low	This is because AEMIF timings are not configured. Use this patch which configures the AEMIF timings for DM36x.
SDOCM00081157 (OMAP-L138)	U-Boot: RMII mode is not working	This is because pinmuxing for RMII is not done in U-Boot. Use this patch which configures the pinmux for RMII mode in U-Boot.
SDOCM00081205 (OMAP-L138)	Audio: depmod/modprobe sequence does not load the required modules.	Insert the required modules manually.
SDOCM00081206 (OMAP-L138)	Audio: Left and right channels are swapped	None
