[En-Nut-Discussion] Updating SP-Duo (was Winavr, studio 4.18 and ethernut 13h, trying to follow your guidance...)

[Harald Kipp]

Hi Karla,

I changed the subject in order to divide the problems you have.

Btw. please note, that it is considered unfriendly mailing list behavior 
not to trim down quotes to the required minimum. It is also very 
difficult to follow as you didn't quote my replies. There are several 
guides available in the Web about mailing list netiquette.

Anyway, never mind...

You probably meant that the command you entered was

  win32/sp2update -v -P COM4 spduo24.enc

I'm not sure what you meant with "changing ports". Did you simply change 
the command line or did you physically change the port. How many serial 
ports does your PC has?

The connection to the Ethernut SPI or JTAG is only to supply power to 
the SPU Duo. Which one you use doesn't matter, but in general you should 
not use both of them.

The status of the Ethernut board doesn't matter either. As long as the 
red power supply LED is on, everything is fine.

This is the basic test that should be done first. If this works, then 
the serial port is fine. In TeraTerm you also selected COM4, right?

Well, I assume, that you kept TeraTerm running while trying the command 
line. This won't work, because TeraTerm blocks the port. Please quit 
TeraTerm and try the sp2update command again.

While reading the README.txt again I noticed, that this subtle detail 
isn't explained. Well, that happens when long term users like me are 
writing instructions for newbies. I'm sorry for that.

Regards,

Harald
