I always use FBOOT as my bootloader on my AtMegas.
I have just assembled one board which uses the Atmega32 Micro. This board has an option of using the Rs232 interface or a usb inteface via the FT232 Vcom port.
If i program the board via the usb interface there is no problem. However when i try to program the board via the RS232 interface i get the following error 90% of the time-
D:\avr\workshop\001BLI~1>fboot /c13 /prelay.hex
COM 1 at 115200 Baud: Connected (One wire)
Error, wrong device informations
What is this "One wire" ?
So far i have
1) checked all solders and continuties -fine
2) after the max232.. i have shorted rx & tx pins. data sent via a terminal bounces back.
3) in desperation replaced max232 with a fresh chip. same problem.
any ideas what i could be doing wrong?
