Firmware 1.45
---------------------------
- Added MassStorage Mode for RIFFBOX2


JTAG Manager 1.69
---------------------------
- Fixed the bug for General Purpose Partition Sizes
- Added feature to switch ON/OFF the MassStorage Mode. For this, please connect an eMMC (either via Direct or ISP interface),
make sure it is detected (on the "eMMC/SD Card" page), and on the 'eMMC/SD Advanced' dialog click the 'MassStorage Mode ON/OFF' button to setup which partitions are to be mounted.
Please note, for stable connection, first of all do reads on the "eMMC/SD Card" page to adjust stable Frequency, BusWidth and Voltage.
After you click "MassStorage Mode ON/OFF" button, current settings for Voltage, Frequencty, BusWidth will be written into RIFFBOX non-volatile memory,
and while the MassStorage mode is ON, upon each connection to USB the RIFFBOX will additinally to normal Control interface enumarate the MassStorage Disks (as if a FlashStick is connected to PC)
eMMC Partition Table FullFlash Image Files Processing Plugin (eMMCDiskPartitions.dll) v3.02
-------------------------------------
- Added support for User Area Partition bounds selection from the JTAG Manager's MassStorage settings dialog
- Added file system detection: the plugin analyzes the partition's data structure to autodetect what file system (if any) is used. The result is displayed in the new "F/S" row
