I tried that, but it does not work. 1500000 is the lowest rate which connects the arduino. All values less gave me: Initializing serprog programmer Baud rate is 1000000 now. serprog: connected - attempting to synchronize ........Error: cannot synchronize protocol - check communications and reset device? Error: Programmer initialization failed.
And with 1500000 i got the same error as with 2000000. The strange thing is why it happens only with function1 and not with the others?! > In the long term we want to provide a fixed firmware for the > communication Atmel processor.

The arduino is very cheap and perfectly to test/add new chips. Normal (commercial) programmers are very expensive. My dream is that some day some one build a parprog which can read and maybe write parallel flashs. :-) Of course, write is difficult, but i would be happy if only reading (dumping) would work. Should be possible with shift registers. > I will commit your patch (with my sign-off) soon, as it seems to be > fine. Thank you very much. Yes it should work. Tested a lot. Erase with function1 is the only negative thing i found. Thank you for commit.
