TSTIK ERRATA
ErrataSinceDescription
Ethernet PHY resetintroduction of TINI400 chipsetThe ethernet PHY is only properly reset on initial power-up of TStik. There is no problem as long as TStik is power-cycled after changing the PHY option jumpers.
Early versions of Configuration Register CPLD are write-only through CPLD revision 1.1 TStik Configuration Register contents cannot be properly read back. The register works fine, but is effectively "write only".
Fixed with CPLD code revision 1.2 on TStik1. The CPLD revision level is printed on a label affixed to the CPLD.

TSTIK ISSUES
IssuesSinceDescription
Flash file system doesn't exist All TINI systems, since introduction of TINI390There is currently no official flash file system for TINI. It would be nice to have one, or at least have a Flash package with low-level access routines for writing, reading, and erasing on-module Flash. TStik has 2 MBytes of flash (1.5 MBytes of this is available, 'user' flash) and it would be nice to be able to use this for data logging, etc.
Battery life (TStik1 only) All TStik1 modules Battery life on TStik1 only when the module is unpowered is less than one year. This affects the NVRAM and the clock and calendar. We are listing this as an "issue" and not "errata" since there is no specific guaranteed lifetime of the battery. You should always store your code in flash anyway (since TINI is subject to heap and NVRAM corruption even with a good battery), so failure of the battery should not cause your application to be lost. Battery life is typically 10X greater on TStik2 due to a new NVRAM circuit design.


TILT400 ERRATA
ErrataSinceDescription
DTR reset connected to serial4, should be serial0. Fixed with hand wire on very early production only. TILT400 2.00 and earlier Due to confusion at the dual DB9 serial connector, DTR reset was connected to the wrong port - Serial4 - instead of Serial0. This has been fixed with hand wire on the back of all shipped TILT400 boards. Fixed in TILT400 2.1.
