AVR-ISP slows way, way, down
2008-02-27 by Dennis Clark
I have an odd behavior I'm wondering if anyone else has seen. I use avrdude on OSX Macintosh to program an ATMEGA8535 via the AVR-ISP. For a while it works fine, programs in fine speed, all is good. After about a dozen downloads the same process has slowed down to one record per second, so a 4K program takes a minute or so to download. I define a record as one "#" printed to the screen from avrdude. My AVR-ISP2 does not do this. Since I'm on a Mac I use the AVR-ISP via a USB/serial dongle I've rebooted the Mac, pulled the USB/RS232 converter out and back in, turned everything on and off and it still downloads at a fraction of the speed that it should. Has anyone else seen this or have any clue why this happens? I've had it happen on two different boards. thanks, DLC -- Dennis Clark TTT Enterprises
