Initial version of tcctool - a utility for talking to Telechips TCC77x-based devices in USB boot mode, allowing code to be uploaded to RAM and run via USB, without any danger of bricking. When your uploaded code crashes, just power-cycle the device and it is back to normal. Requires libusb.

+tcctool
+-------
+
+tcctool is a utility for uploading code to Telechips TCC77x based
+devices in USB boot mode.
+
+It has been tested on the iaudio 7 and Logik DAX DAB/MP3 Player, but
+should work on other devices if the appropriate magic value is
+identified from existing "firmware recovery" programs - see the
+"devices" array in tcctool.c
+
+It can be used for safely testing firmware images before performing a
+firmware upgade.
+
+A first test when using tcctool on a new device can be to upload the
+original firmware. If you do this, make sure you upload the same
+version that is installed on your player - otherwise you may find
+yourself with corrupted config files and music database.
