Release Notes for StellarisWare Revision 7611 (July 2, 2011)
3.2 Bug Fixes in Stellaris Boot Loader
3.2.1 USB DFU device does not pass USB 2.0 Command verifier (Refer-
ence 13432)
The USB DFU bootloader fails some of the Chapter 9 tests that are run as part of the USB 2.0
Command Verifier utility. These failures were a result of improper handling of reset and how the get
descriptor command was handling stalling of unsupported commands. The USB DFU bootloader
now passes all Chapter 9 tests in the USB 2.0 Command Verifier.
3.3 New Features in Stellaris Peripheral Driver Library
3.3.1 Added header files for new devices (Reference 13552)
Part-specific header files have been added for newly announced parts.
3.4 Bug Fixes in Stellaris Peripheral Driver Library
3.4.1 The USBHostEndpointConfig() was setting endpoint 0 speed incor-

The USBHostEndpointConfig() function had an issue when setting the speed setting on endpoint 0
in host mode that caused it to fail to properly set the speed when communicating with devices. This
has been fixed and USBHostEndpointConfig() now properly accesses the speed setting.
3.4.2 Fix order of interrupt disable in USBIntUnregister() and CANIntUn-
register() functions (Reference 13313)
The functions USBIntUnregister() and CANIntUnregister() were unregistering the interrupt before
disabling it, leaving a small window of time when an interrupt could occur after the handler was
unregistered. This has been fixed by reordering the operations to disable the interrupt first.
3.5 New Features in Stellaris Graphics Library
3.5.1 Ftrasterize updated to allow better support for some ISO8859 vari-
ants (Reference 13112)
New command line options have been added to ftrasterize to allow easier generation of some
ISO8859 variant fonts from Unicode fonts. The new options allow a block of characters from a given
