Release Notes for StellarisWare Revision 7611 (July 2, 2011)
3.15 Bug Fixes in EK-LM3S1968 Firmware Package
3.15.1 Display driver disabled chip select too soon (Reference 12987)
The RIT128x96x4Disable() function did not wait for the final SSI transaction to occur pr ior to dis-
abling the chip select, resulting in the final few bytes of the transaction being lost. In some applica-
tions, this would manifest as the right portion of a string or image being cut off.
3.16 Bug Fixes in EK-LM3S2965 Firmware Package
3.16.1 Display driver disabled chip select too soon (Reference 12987)
The RIT128x96x4Disable() function did not wait for the final SSI transaction to occur pr ior to dis-
abling the chip select, resulting in the final few bytes of the transaction being lost. In some applica-
tions, this would manifest as the right portion of a string or image being cut off.
3.17 Bug Fixes in EK-LM3S3748 Firmware Package
3.17.1 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.
3.17.2 usb_boot_demo2 system clock was too slow (Reference 13625)
In previous releases, LMFlash downloads to the ek-lm3s3748 were observed to fail when using the
USB boot loader when usb_boot_demo2 was running on the board. This problem was traced to
the fact that the system clock rate set by the usb_boot_demo2 example was below the minimum
rate of 20MHz required when using USB. The example has now been updated to run with a 50MHz
system clock ensuring that the USB boot loader will operate correctly after usb_boot_demo2 has
been run.
3.18 Bug Fixes in EK-LM3S6965 Firmware Package
3.18.1 Display driver disabled chip select too soon (Reference 12987)
The RIT128x96x4Disable() function did not wait for the final SSI transaction to occur pr ior to dis-
abling the chip select, resulting in the final few bytes of the transaction being lost. In some applica-
