I'm playing around with WinAVR for the first time using
this usbasp programmer.
When writing a hex file to flash avrdude gives the following warning line at the start:
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
It then goes on to write to flash without any apparent problem.
Now, since I just bought the usbasp, I'm assuming the firmware is relatively current. In any case I can't update the firmare since I don't have another isp programmer.
I'm not sure whether that warning is something to be concerned with or not.
I'm wondering if the issue is that the most current version of WinAVR available is 5 years old (WinAVR-20100110) and uses avrdude version 5.1 (the usbasp programmer says to use with 5.2 or newer - though avrdude does list it as a supported programmer)
I tried updating WinAVR with the most current avrdude (6.2) using the directions found
here but then I get a the error line:
avrdude: syntax error at C:\WinAVR-20100110\avrdude.conf:999
So my question is: Should I just stick with WinAVR with avrdude 5.1 and not be concerned about the inability to set sck period? or is there a better way to update WinAVR to a newer version of avrdude?
