Details:

Dears,

I am new in using AVRDUDE.
I am using it with avrispmkII programmer.

I found out two features I think can be useful.

1) about the -B option [ISP-frequence settings]
   I realized that avrdude just considers the last occurrence
   of the option, but it can be very useful to have a dynamic
   frequence.
I mean, for example, a command like

.... -B 8 -U:.:w.... -B 1 -U:.:w....

where I would like to use a lower frequence for the first write
and a higher frequence for the second write.

I need it in order to upgrade fuses in the first write
satisfying the 1/4 MCU frequence bound
and then speeding up before the ROM upload.


2) about -U option, I think it would be better
   to use a non-":a" format as default in case of read operations
   necause it does not make sense.
Really, I had other troubles in using -U:<memory>:r case
and for the moment I gave up, I will just use write.



A Minor comment is about :

-E option determines a warning, according to the documentation
which states it can be used just with JTAG ICE,
but really it appears working [at least for the case "-E noreset"
I needed].
