avrdude can't talk to my fuzebox

by jean-paul on Sat Dec 13, 2008 7:54 am

Hi,

I'm having a little problem with getting avrdude to read / write from the fuzebox. I'm running the latest version of Leopard.

The symptoms:

- Fuzebox is powered by the cable, so the device is correctly enabled in Leopard (drivers are working).
- The /dev/uc.usbserial-xxxxxxxx device is present.
- I've modified the cable to invert RTS#.
- Fuzebox reboots after avrdude shuts down, so the RTS# 'hack' works.

avrdude output:

Jean-Pauls-MacBook-Air:~ jp$ avrdude -p m644 -c stk500v1 -P /dev/cu.usbserial-FTRHXC2W
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

Any help would be greatly appreciated! :D

Cheers,

Jean-Paul

P.S. I was just wondering, do I have to set baud rates at all?

I've checked the pins on the board and only the black and brown pins are connected (to GND). From what I can tell, this is supposed to be this way. Other than that, all pins seem to be working fine.

So hopefully it's a software thing.

Cheers,

So,

I managed to hook it up to a PC again:

C:\>avrdude -p m644 -c stk500v1 -P COM4

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.08s

avrdude: Device signature = 0x1e9609

avrdude: safemode: Fuses OK

avrdude done. Thank you.



So it's definitely a software thing. :D I really want to have this working on my Macbook laptop because that's my main dev system.

Thanks in advance,

Jean-Paul
