Won't generic serial bitbang work with the FTDI hardware?

never tried this, maybe you can investigate it? I think the VCP driver has a bad timing behavior but maybe the idea is just too simple and no one tried it before...

That would certainly be a show-stopper.

I don't have a lot of incentive to work on it, as I've got an AVRispmkII.

Hi,

I want to know if it's possible to burn bootloader in a diecimila with an atmega8 using the parallel programmer. I've already tried but it says that the avr does not respond, that was expected the signature of the atmega8.

Thanks

It is possible, but this thread discusses the FTDI BitBang hack. You can use the modified Arduino board to burn the bootloader to your ATMega8 chip.

Parallel Programmers often have timing problems, I don't use them anymore.

I followed the instructions in the photo shown below but THEY DID NOT WORK:



I checked the board schematic and I got it to work.

This should work for the Duemilanove or the Diecimila (I used the Duemilanove) but I checked the schematic for both.

The way I wired it was

1 - 12
2 - 13
3 - 11
4 - reset.

I am sorry for using the same colour for all and the bad photo but it is the best I can do!



I also had a problem with the GUI yuki-lab.jp Version 1.0.5

If the file name is too long it gives error. I had the GUI in my documents and I moved it to program files. I think the long file names caused problems.

I got it working now so I am happy.

Also if the "display window" option is ticked it will not program

I will try contact author.

Thanks all

@bohne: Did you find time to summarize your experiences burning the bootloader from macos?

[Reply #52 on:]

sorry, no

[Reply #53 on:]

But you got it working? Any hints?

i can't upload bootloader for atmega328P
first of all i've to add "-F" option or i get the following error:

Code:

avrdude.exe: BitBang OK
avrdude.exe: pin assign miso 3 sck 5 mosi 6 reset 7
avrdude.exe: drain OK

 ft245r:  bitclk 4800 -> ft baud 2400
avrdude.exe: ft245r_program_enable: failed
avrdude.exe: initialization failed, rc=-1
             Double check connections and try again, or use -F to override
             this check.


avrdude.exe done.  Thank you.

then the Fuse code i get are:
FF FF 07
bitlock 3F ( finally something right  ;D )

if i try to writre the suggested DA FF 05 i get:

Code:

avrdude.exe: BitBang OK

so lets carry on with old values...
choosing the right bootloade, "Erase - Write - Verify"... after some sec i get "the program isn't responding....", and still like this after over 5 minutes... the bottom bar is completely empty.. tested on Win7 with administrator privilegies to user and to programs... ARGH!
maybe because the file are in "D:\" ????

maybe after i'll test into linux... last (big) hope  

[Reply #55 on:]

ugh i have the exact same problem as you same error and everything. Did linux fix it? I really need to get the working before the semester ends
