Hi,
I want to add a new network protocol to u-boot. However it seems that the
most straightforward way to add a new protocol is to add it to NetLoop's
supported protocols. Of course, I would create a .c/.h pair of files to
manage the protocol and use CONFIG_XXX to ensure it doesn't add unnecessary
code.
My problem is that the protocol is used for internal testing procedures to
make u-boot act as a command server allowing a host pc to read/write
memory, use i2c, program various data into flash (Mac Address, ID's, ...)
and so on. The protocol could be gpl'ed and documented, yet it still have
limited use outside our test procedure.
So what could be the best way to achieve that goal? Should I replicate the
whole NetLoop functionalities adapted to my protocol and put it on a .c/.h
pair of files (and still using CONFIG_XXX) and keep these files available
on request, or must I add that protocol to the "official" list of supported
protocols? The second option is not very valuable for the community I
think, but the first solution seems to be a very nasty hack.
What's your opinion ?
Regards,
Fred.

U-Boot has a network console (see doc/README.NetConsole). Can you not
use this for your tests?

Hi Albert,
Yes, I could, but the purpose of my protocol is to be software driven and
not human driven. Also error checking is extremely important when testing
boards.

Fred.

Not sure I get you there. The netconsole is just a way to access the
U-Boot prompt from the network; commands can be input on this prompt,
and results from it can be processed, by a human or machine alike.

Yes it could be software driven, but it's much more complex to manage and
error checking could be even more complex.
Anyway, I've implemented the protocol and it's working properly. As it's
used for internal testing, i'm not forced to make source code available, so
this issue is closed.
Thanks for your answers,
Fred.

GPL will hit as soon as you distribute any binary containing this
code.
