Release Notes for StellarisWare Revision 6075 (June 4, 2010)

10.8.2 usb_host_audio application does not display time information (Refer-

ence 11974)

The usb_host_audio application did not properly compute the duration in minutes and seconds for

wav ﬁles that were selected. The application also failed to update the elapsed time as a ﬁle was

played. Both of these issues were ﬁxed.

10.8.3 usb_stick_update would not enumerate drives in all cases. (Refer-

ence 12241)

The usb_stick_update only enumerated USB MSC devices if they were present when the applica-

tion started. The usb_stick_update now properly enumerates devices by forcing the OTG controller

to indicate a host connection which allows USB MSC devices to properly enumerate.

10.8.4 Fixed left/right channel swap on I2S DAC output (Reference 12245)

The left and right channels were swapped on the I2S DAC outputs being sent to both the headphone

and line out jacks on the board. The DAC now swaps the two channels so that they appear correctly

on the headphone and line out jacks.

10.9 Bug Fixes in EK-LM3S1968 Firmware Package

10.9.1 RIT display driver used wrong SPI mode (Reference 12217)

The display driver for the RIT 128x96 panel on the evaluation board used the wrong SPI mode.

This caused the Stellaris SPI port to transition the data line on the same clock edge that the display

controller read the data line. While this managed to work, the correct SPI mode is now used.

Additionally, some improvements were made in the handling of the SPI interface, resulting in better

performance of the display driver.

10.9.2 Added MPU region to mpu_fault example for bit-banded SRAM (Ref-

erence 12235)

A new MPU region has been added to the mpu_fault example to allow read/write access to bit-

banded SRAM. This is required by the updated display driver, which uses the bit-banded SRAM

region for storing ﬂags.
