New Tahoe-II firmware

We have just updated the Tahoe-II firmware.    This release adds file system support and fixes a number of issues with the SPI bus.   

When using the file system, the key limitation to be aware of is that the SD card you use must be formatted with FAT32 and NOT contain a Master Boot Record (MBR).  You can re-format cards under Windows to FAT32, but Windows will not remove the MBR.  We have a utility that will do this (scroll to the bottom of the download page), but please use it with extreme care!  It’s early days for the Micro Framework file system and future releases will fix some of these issues.
