Not at all!!

You might want to also announce your tool on:

the "Development tools" section of Silabs forum:
http://www.cygnal.org/scripts/forumdisplay.cgi?action=topics&forum=Development+Tools&number=4&DaysPrune=45&LastLogin=
It certainly is not off-topic there and Silabs
own tools have their short-comings.


Also it would be of interest to some people at:
http://www.8052.com/forum/
Be warned: the climate on that forum is what I'd
perceive as somewhat rough.
Denouncements like "kitchen sink" might be
dropped over there (ignore).
The neat interface you provide for programming the devices like
"cat image > /sys/class/c2port/c2port0/flash_data"
might be of interest for other CPUs as well.

Your site is very difficult to find with a search machine.
Please add stuff like: without EC2 or EC3 debug adapter, bit banging,
ISP somewhere.

Would it be correct to assume one would only have to adapt:

	access		: wwpc1100_c2port_access,
	c2d_dir		: wwpc1100_c2port_c2d_dir,
	c2d_get		: wwpc1100_c2port_c2d_get,
	c2d_set		: wwpc1100_c2port_c2d_set,
	c2ck_set	: wwpc1100_c2port_c2ck_set,

for an (appropriately protected) PC parallel printer port
and could have a linux based programmer up and running? ?)


I'm CC'ing this mail to Ricky White, author of ec2drv.
ec2drv http://ec2drv.sf.net/ is a user-space linux application
for programming and debugging Silabs devices via the EC2 and
EC3 debug adapter.
Although your code is kernel-space and no EC2, EC3 adapters
are involved you can maybe find synergies.
