I have now invested some time to install Atmel Studio on a Windows 7
partition, and to check how Atmel Studio writes to eeprom.
Short Summary
-------------
- Installing and getting started with Atmel Studio is a pain in the
neck if you are used to nice avrdude and to installing rpm packages
(and, why does Studio use -v for specifying options with 2 perfectly
different semantics in a single line?).
- The effort to install Atmel Studio is nevertheless worth while, even
if, later, you only use avrdude: it allows you to get the latest
firmware update for your jtagice3 (for me that meant an upgrade from
firmware version 1.37 to version 2.21).
- However, the firmware upgrade does not solve the problem discussed
here.
- Failures on single-byte eeprom write operations do not only occur
with Avrdude, but also with Atmel Studio - maybe somewhat less
frequently than with Avrdude, but so often that the jtagice3 is
practically useless if you want to write to eeprom positions.
- It looks like the problem is not necessarily due to the
implementation of Avrdude (or Atmel Studio) but could just as well
be a flaw in the implementation of the firmware of the jtagice3.
- To be repeated here: corresponding single-byte operations work
perfectly when using a JTAG ICE mkII - nevertheless, I will now
confection a new target board with a new processor to make sure that
the problem is not a due to the specific processor I am using.
Detailed description
--------------------
In the attachment, I join a file into which I have pasted the console
I/O for both a single-byte read and a single-byte write, and both for
Avrdude and for Atmel Studio. Atmel Studio only has a simple -v option,
which does not provide much information on how Studio proceeds when it
writes to eeprom.
