Could you explain without retorical words what is your project about?

Yes. I'm going to use the MCT v1.81 R22 sources.elrules wrote:Ok, so you want to program a new bootloader and maybe some changes to MCT, right? to make it easier and more platform independent the process of updating the firmware

If anyone is interested in testing I can post a diff to the MCT v1.81 R22 sources, but you'll need to install the new bootloader and use my test app' firmware - which can do WDT resetselrules wrote:It is going to be an open-source project, right?

/* -> c.Succ-U-Bus
*
* Status: Beta
* Copyright: (c) 2009, Ken Forgettable
* Version: see version[] below
* Date: 090929
* Purpose:
* Headless Megadrum AVR bootloader for ATmega32 (?), ATmega324p and ATmega644p.
*
* Built with:
* AVR Studio 4.16.628
* GUI Version 4, 16, 0, 626
*
* Plugins:
* AvrPluginAvrAsmObject 1, 0, 0, 47
* AvrPluginavrgccplugin 1, 0, 0, 10
*
* using WinAVR-20081205
*
* Add to project config [All files]
* -fno-inline-small-functions
* -fno-inline-functions
*
* NB. Build and simulate for ATmega644P at 16MHz as the code size is largest.
*
* 090622 - Test: compiled to 324p @16MHz - ok
* 090703 - Beta: compiled to 324p @16MHz - ok at 1694prog, 800data
* 090924 - prettyfied, tidied globals, added version string - 1812prog, 798data

* app FW, there should not be a problem debugging.
*
* So, this bootloader insists on running with the mCU in a known state and
* uses a watchdog reset to achieve this ;¬/
