Hi to all!
I am new to this, so sorry for my maybye stupid question. But I have similar problem to this..
I´m building 3D printer with minitronics board. I´ve downloaded all materials from here: http://reprap.org/wiki/Minitronics_10
. I made the board myself due to schematic. Standart minitronics boards have ATmega1281 and problem is that schematics in that link say ATmega2561. I didn´t noticed it before, but now I have fully assembled and functional board with mega2561. I´ve tried to burn bootloaders from 1281, it seems to work partly, I can´t connect to IDE and upload MARLIN or other programs..
This state is because proccesor signature is wrong. IDE says expected value is 0x1E9704 but mega2561 have signature value 0x1E9802.
Any ideas how to make it work?
I´ve also tried bootloader from bilbos first link, but same problem.. AVRDUDE did not recognized right proccesor.. Do you know how to ignore or override this check?
Thanks for any help!
