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.
