Hi Luca, All,
I'm attempting a port of your driver to the AF9015 chip, and slowly
making progress. Just for reference, I've never written drivers for
computers before, pretty much all my programming experience is in
embedded stuff, it's much simpler there.
My biggest stumbling block at the moment is the firmware file. How did
you know where to extract the firmware from (af9005.fw &
af9005-script.h)? Was it simply through the documentation you were
given, or was it through windows snooping?
both: from the documentation I knew the firmware download sequence, I
also had the firmware in a firmware.h file. Since it wasn't working I
did some snooping and got the firmware downloaded under windows (which
is different that the one that came in the documentation). The same can
be said of the register initialization sequence.
I have some rough python scripts to decode the windows snoop file, but I
think they're af9005 specific.
I've sent Afatech an email asking for access to documentation on this
newer chip, no reply yet, so just working with what I've got. This chip
is at least somewhat different to the 9005, as simply adding the PID/VID
of my device into the driver didn't work, I get a "af9005: boot bad
config header." An extra err printout tells me that the buff[2] value
that gives the "boot bad config header" is 0x0 when it should be 0x11
for your driver.
I'm Bcc'ing my contact at afatech, he's been very helpful so I hope
he'll contact you privately.
Bye

Luca
