... I may have a go at implementing IAP (In-Application Programming) sometime ...
That would be very nice!
I assume the putty way of flashing works over USB, correct? For me the big step would be to flash via ethernet.]]> auser Ormerod Sun, 17 May 2015 10:17:39 -0400 https://reprap.org/forum/read.php?340,509537,509972#msg-509972 Re: Duet Erase button https://reprap.org/forum/read.php?340,509537,509972#msg-509972
1) Open PuTTY (or your favourite terminal program) and connect to the flashed Duet with 1200bps and XON/XOFF activated
2) Run bossac -u to unlock all the Flash pages
3) Flash your ROM as you normally do (bossac -e -w -v -b )

That should be sufficient from my point of view, but I may have a go at implementing IAP (In-Application Programming) sometime in the future. Dave has already pointed out a nice way how this could be done, but I figure that will require some more work to ensure an f_read equivalent works while the actual firmware is being overwritten.]]> chrishamm Ormerod Sun, 17 May 2015 09:51:06 -0400 https://reprap.org/forum/read.php?340,509537,509926#msg-509926 Re: Duet Erase button https://reprap.org/forum/read.php?340,509537,509926#msg-509926

Just don't put that G code in your print files! I suggest making sure the code chosen is unlikely to be entered accidentally by someone making a typo. Maybe it should need an unusual parameter or password.

Yes good point I suppose someone Could do S4321 by mistake how about M999 ERASE or M999 SERASE or something like that?

OK, I'll see if I can slip this into my 1.09 version, which I was hoping to release later today. We already have the M999 command for software reset, so how about something like M999 S4321 to mean erase and reset?

That sound good to me (Means I'll be able to remove my remote switches and tidy it up a bit)

You do need to press the Erase button to upload new firmware. However, it would be possible to add an "Erase firmware and reset" gcode sequence to the existing firmware, which would avoid the need to press the Erase button in future.

Well, I'd be all for adding a gcode for that function, if it's not too difficult.

I also like this idea


Yes Please

The reason I ask is I want to mount a reset button outside the Duet case and that's easy to connect to the required signals
I believe pin 4 on the expansion connector is reset and there are plenty of GNDs about
but not so with the erase button , the only place I can see to take the erase signal from is the connection on the erase switch

So if pressing the erase button is not strictly neccessary every time I can miss that off and just fit the reset
