bad upgrade to software 1.6.8? (avrdude: stk500..programmer is not responding)

I Upgraded to 1.6.8 (sorry do not remember what is was)

Using Win 7 Arduino Uno (IEIK) Was programming and working before upgrade But after upgrade I am getting

((Sketch uses 1,602 bytes (4%) of program storage space. Maximum is 32,256 bytes. Global variables use 45 bytes (2%) of dynamic memory, leaving 2,003 bytes for local variables. Maximum is 2,048 bytes. avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd5



avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xd5 Problem uploading to board. See for suggestions.))

Tried (Look at forum and tried) Going back ver 1.6.7 (Same thing) Moving USB cable PC (Same thing) PC and software sees Move of Arduino Bd

Forum had me look for Tx/Rx leds (no indication led working )

Any other thoughts or do I need AVR USBASP Programmer do to a bad bootloader

1.6.8 has problems on Windows - though that doesn’t really look like the usual problem.

I can’t recommend any version later than 1.6.5r5 - the more recent versions have had new bugs, and in the case of 1.6.8, a very severe serial handling bug on windows.


I did as you asked and still getting the same.
