DASA not working

by Areshiones on Fri Apr 03, 2009 2:08 pm

Hi,

I am using a USB-Serial cable that is connected to the DASA kit you sell. The DASA is connected to the Fuzebox. The Fuzebox is powered up and I run avrdude to try reading from the chip but I am not able to do it.

I already tried video, audio and bootloader so everything seems fine. What can I do to communicate with the Atmega?


P.S. When I "unplug" the DASA from the board the LED blinks three times as if a reset is being performed

unfortunately the dasa programmer is too 'crappy' to program it :( you would need to put a buffer on the programmer lines because they are being too dragged-down by the SD card resistors. alternately you can just 'clip' the SD card resistors. i dont think SD support has been really nailed down anyways

In this case, if I use the USB TTL would mean I won't have this issues?

yes it would be OK, assuming that you have a kit or a preprogrammed fuzebox chip with the bootloader
