Summary of change:
Com 1 is used as communication port. I get into bootloader mode using the terminal program. (Bray) I send Manmcbffmcb in the terminal program. I then change to 19200 baud and send S to check the reply. The reply from the controller is AVREFI1. I then send v to the controller. The reply is 20. I exit the terminal program and start AVRprog.exe I have successfully uploaded vems.hex (from v3_firmware_2004-11-24_v9 ) into the ATMEGA using the AVRprog.exe. ''Try v8, to make sure.'' I exited the program using the exit button on AVRprog.exe I can download config.mtt from the controller using the terminal program (Bray) and the mcd command. But I can still not get the Megatunix to communicate to the controller. I started the Megatunic via command prompt. Then I changed the com port to COM1. This is the message I get from Megatunix: The MegaSquirt ECU appears to be currently disconnected. This means that either one of the following occurred: # Wrong Comm port is selected on the Communications Tab. ''Possibly, but you aleady know which com port you used with Bray terminal.'' # The MegaSquirt serial link is not plugged in. ''Unlikely...'' # The MegaSquirt ECU does not have adequate power. ''If other apps / terminal can talk to it, it's got enough power.'' # The MegaSquirt ECU is in bootloader mode. ''Check with a terminal, or better with prog.pl. Do a verify @ 19200, and if you don't need to "t" talk to the "msavr" application first, it's in bootloader mode. We already know it's not, as you can "mcd" the application. I think this points to a lower-level MegaTunix<-->firmware problem of some kind.'' What do I do wrong??????????????????????????????/
