From 71cdf0043740361416df97a432dc4f0da225a099 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Sat, 20 Oct 2007 09:11:34 +0000 Subject: 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15217 a1c6a512-1295-4272-9138-f99709370657 --- utils/tcctool/README | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 utils/tcctool/README (limited to 'utils/tcctool/README') diff --git a/utils/tcctool/README b/utils/tcctool/README new file mode 100644 index 0000000000..c2fa8a0fb9 --- /dev/null +++ b/utils/tcctool/README @@ -0,0 +1,29 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + ****************************************************************************/ + +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.
