Hi,
I had posted this issue a year ago, but got no reply. In the meantime,
I was using AVR studio for programming, so I forgot about this.
Now I'm returning to avrdude, and I again encountered curious problem .
My avrdude command line is:
>avrdude -p t26 -u -U micro-cntr.hex -U hfuse:w:0xF6:m -U lfuse:w:0xE1:m
> -U lock:w:0x3c:m
While writing hfuse, I get this error message :
avrdude: reading input file "0xF6"
avrdude: writing hfuse (1 bytes):
Writing | ***failed;
################################################## | 100% 0.19s
avrdude: 1 bytes of hfuse written
avrdude: verifying hfuse memory against 0xF6:
avrdude: load data hfuse data from input file 0xF6:
avrdude: input file 0xF6 contains 1 bytes
avrdude: reading on-chip hfuse data:
Reading | ################################################## | 100% 0.03s
avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
0xf6 != 0x16
avrdude: verification error; content mismatch
I checked the datasheet, and 0xF6 should be correct (unprogrammed fuses are 1).
AVR studio too has no problem writing (and reading ) hfuse as 0xF6 .
So what could be the problem ?
Thanks,
--Royce
