Summary: stk500 fosc command broken
Original Submission: There is a bug in stk500.c that prevents the fosc command
from
working. Here is an example:
avrdude> fosc 3.7M
>>> fosc 3.7M
avrdude: stk500_set_fosc(): f = 3.700 MHz too high, using 3.686 MHz
avrdude> parm
>>> parm
Vtarget : 5.1 V
Varef : 5.1 V
Oscillator : 16.098 kHz
SCK period : 1.1 us
This line
cmatch = (unsigned)(fbase / (2 * v * ps[idx]));
needs to change to this
cmatch = (unsigned)(fbase / (2 * fosc * ps[idx])) - 1;
I will submit a patch for this.
