I've been working on making the arduino single sided serial board S3v3 for the past 15 days , i etched , soldered all the components and also managed to load the bootloader using USBasp and the ICSP headers.
But when i try uploading the sketches to the board its giving me the following errors.
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x00 avrdude: failed to write flash memory, rc=-4 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x54
ive googled a lot on this but it seems to be a less frequent error ( ? ).
ive been trying to sort this problem for the past one week so any inputs would be very useful.
PS: I followed the instructions on the official Arduino page for the S3v3 schematics.
and also i followed this http://www.instructables.com/id/Make-your-own-arduino-serverino/step4/Programing-the-ATmega8-or168/ for uploading the bootloader
Im using an Atmega168. (if it helps)
