Release Notes for StellarisWare Revision 7611 (July 2, 2011)

3.10 New Features in Stellaris Utility Librar y

3.10.1 swupdate.c can be conﬁgured not to use ROM boot loader (Refer-

ence 13270)

Previous versions of swupdate.c, the module used to notify Ethernet applications that a ﬁrmware up-

date is being requested and to transfer control to the Ethernet boot loader, always called the ROM-

based Ethernet boot loader if it was available. When an application is making used of a customized

Ethernet boot loader in ﬂash, however, this is undesirable so a #deﬁne has been added to allow this

behavior to be overridden and have swupdate transfer control to a ﬂash-based boot loader even if a

ROM-based one is available. To activate this behavior, ensure that USE_FLASH_BOOT_LOADER

is deﬁned when you compile swupdate.c.

3.10.2 ustrncpy and ustrlen functions added to ustdlib (Reference 13422)

New function ustrncpy and ustrlen mimicing the C runtime functions strncpy and strlen, have been

added to the ustdlib module and usvnprint and ustrstr have been modiﬁed to use these functions

rather than the C runtime versions. This allows ustdlib to be completely independent of the C

runtime library.

3.11 Bug Fixes in DK-LM3S9B96 Firmware Package

3.11.1 SimpliciTI addresses corrected to ensure uniqueness (Reference

13505)

Despite the fact that the code commenting indicated that SimpliciTI low power RF device addresses

were being set using the least signiﬁcant 4 bytes of the Ethernet MAC address, the code was, in

fact, using the most signiﬁcant 4 bytes. As a result, attempts to communicate between multiple

Stellaris boards via the SimpliciTI protocol would frequently fail since the boards had the same de-

vice addresses. This has now been corrected and the correct information is being used to generate

the device addresses, thus allowing multiple Stellaris boards to communicate correctly.

3.11.2 Fix value of dummy CRC in FatFs SD card dr iver that was causing a

problem with some SD cards (Reference 13300)

A value of 0 was being used for dummy CRC for some SD card transactions, when it should be

0xFF. This only affected some SD cards. The driver was changed to use 0xFF for the dummy CRC

value.
