Hello list, I just wanted to ask if anyone else has trouble with avrdude the way I do: I have some tiny2313s which are preprogrammed with the CKDIV8 fuse and additionally have the 4MHz internal oscillator active. When I try to do anything with them using avrdude, the very first handshake (device signature) fails. Sometimes the first two bytes arrive OK, but the third is garbled, sometimes all bytes are trash. I do not remember the exact values I got, however.
When I enter Ponyprog I can program the devices fine. When I tell it to set the fuses to use an external crystal (slow rising power, no CKDIV) the device can be accessed just fine from avrdude also. Programmer: STK200 Cable length: around 20cm OS: Linux joelaptop 2.6.26.1 #9 PREEMPT Sat Dec 27 01:33:46 CET 2008 i686 Intel(R) Pentium(R) M processor 1400MHz GenuineIntel GNU/Linux AVRDude: Version 5.5 (Gentoo package dev-embedded/avrdude-5.5) If it is helpful to provide the exact output or more debugging info, I can flash back the fuses to the 4MHz osc. in order to reproduce the problem.
