Otherwise, the chip may be running a program that outputs values on the TPIDATA pin and that could cause the MOSI/MISO link check to fail. Also increase RESET assertion time to 128ms (worst-case specified in the ATtiny9 datasheet). _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Thu 27 Apr 2017 11:05:49 AM MDT Name: avrdude-bitbang-reset-fix.diff Size: 539B By: dmosberger <http://savannah.nongnu.org/patch/download.php?file_id=40520> _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?9320> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
