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

10.7.2 USB Drivers Now Support Windows 7 32-bit and 64-bit Versions

(Reference 11555)

The SW-USB-windrivers-xxxx.zip USB driver package has been updated to support both 32-bit

and 64-bit versions of Windows 7. The package includes 64-bit versions of URLs lmusbdll.dll and

lmdfu.dll allowing 64-bit applications to access these interfaces. The Device Firmware Upgrade

driver has also been rewritten to use the Microsoft-supplied WINUSB interface rather than libusb-

win32 which is not currently fully supported on Windows 7.

10.7.3 Add DMA support to the USB audio device examples (Reference

11677)

In previous releases, the USB device audio examples did not use uDMA for transfers. The stand-

alone usb_dev_audio and usb_dev_caudiohid examples now both use uDMA for transfers.

10.7.4 Windows tool Visual Studio projects updated to VS2008 (Reference

12138)

The project ﬁles included in the tools directory for the various VisualStudio applications and DLLs

have been updated to support VisualStudio2008. They were previously for VisualStudio2005.

10.7.5 New dbeeprom example application added (Reference 11936)

A new example application, dbeeprom, has been added to the dk-lm3s9b96 StellarisWare release.

This allows the contents of the ID EEPROM on option daughterboards to be read and written and is

intended to allow recovery from cases where a user application accidentally corrupts or erases the

content of this device. The application provides a command-line interface via UART0 and is capable

of writing the ID block for both the SRAM/Flash/LCD and FPGA/Camera/LCD daughterboards.

10.8 Bug Fixes in DK-LM3S9B96 Firmware Package

10.8.1 Allow SafeRTOS demo to be moved from location 0 (Reference

12086)

The vector table address in the xPORT_INIT_PARAMETERS structure that is passed to SafeRTOS

was hard coded to 0, which prevented the SafeRTOS scheduler from starting if the vector table was

not actually located at 0 (for example, when using a boot loader). That address is now ﬁlled in at run

time from the NVIC vector table base address register, therefore reﬂecting the actual vector table in

use. This does not affect the operation of the demo as it is provided, but does make it possible to

change the base address of the demo (in the linker script) and have it continue to work correctly.
