[avrdude-dev] [patch #9315] Add PRUSS programmer type for xmega pdi

[Enric Balletbo i Serra]

Follow-up Comment #2, patch #9315 (project avrdude):

Joerg, thanks for you answer.

Some comments below.

About the documentation missing I'll prepare a second version including the
.texi and man page files. About hardcoding the path name I have another
version of this patch that uses and extra parameter to specify the location of
the firmware files, but seeing your answer might be not enough, I'll try to
investigate how to handle this part with autoconf parameter and see how it
works on Windows

Finally, the firmware is open [1] so that shouldn't be a problem, I guess

[avrdude-dev] [patch #9315] Add PRUSS programmer type for xmega pdi

[Joerg Wunsch]

Follow-up Comment #1, patch #9315 (project avrdude):

Basically, a good idea.

Documentation patches are missing (either to the .texi or the 
man page file, preferrably for both).

I see a couple of problems with the firmware files though:

First, we are guests on the FSF's servers, and they only accept 
opensource projects.  Thus, we are not allowed to host a 
closed-source firmware for the programmer.

Second, hardcoding a path name in the application is completely 
a "don't ever do this".  This should preferrably be handled 
using autoconf parameters, depending from --prefix.  However, 
on Windows, this is usually completely different.  See 
winconf.c for how this is implemented wrt. avrdude.conf.

Details:

This patch adds XMEGA PDI programming support using the Programmable Realtime
Unit (PRUSS) available on AM335x based boards like Beaglebone Black. You can
program an XMEGA in-circuit without requiring any external hardware, with only
a few extra components in your circuit. Note that the programmer needs a
custom firmware that needs to be loaded to the PRU (also attached here).
Avrdude loads the firmware and communicates with it to be able to program the
firmware on XMEGA. E.g.

  avrdude -p atxmega16d4 -c pruss -e -U flash:w:my-firmware.hex
