Release Notes for StellarisWare Revision 8028 (September 9, 2011)

2.7 New Features in Stellaris Utility Library

2.7.1 New functions added to ustdlib (Reference 13890)

Previous versions of the ustdlib module included a call to the C runtime function strncmp which,

with at least some toolchains, caused the C runtime library to be pulled into the linked image.

Since ustdlib was intended to provide access to commonly-used functions without the need to link

the C runtime, this was somewhat unhelpful so new functions ustrcmp and ustrncmp, mirroring

the standard strcmp and strncmp functions, have been added and the previous call to strncmp

removed.

2.8 New Features in DK-LM3S9B96 Firmware Package

2.8.1 FontView example application added (Reference 13807)

A new example application has been added to allow the contents of a Stellaris graphics library font

ﬁle to be displayed. This program illustrates the newly-added international character set support

and will show all the glyphs encoded in a binary font stored as FONT.BIN in the root directory of

the SDCard FAT ﬁle system or, if this ﬁle doesn’t exist, the contents of a sample font built into the

executable.

2.9 Bug Fixes in DK-LM3S9B96 Firmware Package

2.9.1 Broken link in safertos_demo web site ﬁxed (Reference 13637)

An incorrectly named link in the safertos_demo example’s internal web site has been ﬁxed. The

previous version failed to show the block diagram image due to an error in the image link.

2.9.2 The usb_dev_msc application was using a slow SSI clock (Reference

13742)

The USBDMSCStorageOpen() function was calling the disk_ioctl() function to turn on the power to

the SD Card interface when it had already been initialized. This had the unintended consequence

of resetting the clocking to the SSI peripheral back to a 400-kHz clock and not the 12.5-MHz that

should be used. The call to the disk_ioctl() function has been removed and the access speed to

the SD interface is now running at 12.5 MHz for this application.
