Bootloading Monochron

by Squar0L on Sun Mar 14, 2010 10:01 pm

I'm trying to load Xdalichron through a Sparkfun FTDI adapter, but not sure if Monochron has a bootloader. This is how my avrdude command look like:
Code: Select all | TOGGLE FULL SIZE
make program
avrdude -p atmega328p -P com7 -c stk500 -B 19200 -U flash:w:monochron.hex
avrdude: stk500_getsync(): not in sync: resp=0x00
make: *** [program] Error -1073741819

Then avrdude crashes. Any idea? My FTDI has DTR for the reset - would that still work?

I hope this helps. I was having difficulty programming my monochron for a while but I finally figured it out. When I initially connect the FTDI cable to a monochron that is powered on the screen goes blank for a few seconds. I have to hit enter on the avrdude command while the screen is black or else I will get the error you are getting.
