Using avarice 2.13 (linux) with dragon (version 7.34) in debug wire mode I recognized, that the device doesn't actually "reset" (sfrs not initialized). Investigating that shows a comment and workaround in "jtag2run.cc". I disabled the workaround and until now I can't see the mentioned problems and the sfrs are initialized as intended. Maybe be disabling the workaround could be implemented as commandline option.

void jtag2::resetProgram(bool possible_nSRST_ignored)
{
#if 0	
    if (proto == PROTO_DW) {
	/* The JTAG ICE mkII and Dragon do not respond correctly to
	 * the CMND_RESET command while in debugWire mode. */
	interruptProgram();
        setProgramCounter(0);
    } else {
#endif	
	uchar cmd[2] = { CMND_RESET, 0x01 };
	uchar *resp;
	int respSize;

	doJtagCommand(cmd, 2, resp, respSize);
	delete [] resp;

	/* Await the BREAK event that is posted by the ICE. */
	bool bp, gdb;
	expectEvent(bp, gdb);
#if 0	
    }
#endif	
}
