Commit Message

This patch adds support for reading the trac register if atusb firmware
reports tx done. There is currently a feature to compare a sequence
number, if the payload is 1 it tells the driver only the sequence number
is available if it's two there is additional the trac status register as
payload.

Currently the atusb_in_good() function determines if it's a tx done or
rx done if according the payload length. This patch is doing the same
and assumes this behaviour.

Just an RFC, need another weekend to test it.

I've been fighting all night thinking the issues were on the atusb side
(it was horribly difficult to get the atusb toolchain up and running,
I'll send a patch to update the instructions), in particular because of
the data[2] definition which needed to be declared static outside of
the functions (see the other mail) and, I guess, because of this
beginner error: I was using skb->data[1] but of course it can't work.

Anyway, this patch works, I've tested it by:
- associating a device (an Arduino Nano running Zephyr, btw)
- having the atusb disassociating the nano successfully (trac = 0)
- reassociating the nano
- powering off the nano
- trying to disassociate

The disassociation notification transmission fails with a TRAC status
NO_ACK. So:

Tested-by: Miquel Raynal <miquel.raynal@bootlin.com>

I still have the filtering thing to improve, I'm not sure I'll have
time to do that this week. I need some time to prepare the slides now
that the demo works :)

Really? for me it was just apt install avr-gcc libc-avr (or what the
debian packages name is). Then the dfu-util and be sure you invoke
dfu-util (as root because you might need some udev rules otherwise)
when the atusb is booting up.

mhh, I am sorry. I am not sure if I understand what you mean? Does the
firmware patch have issues regarding data[2]?

ok, no problem. Thanks for testing it. I am happy that if I could help

I feel so bad. All the instructions I could find (from 2011) advised to
download an old gcc, an old binutils and old avr-lib, to compile
everything by hand... 2 out of 3 archives returned a 404 error, the
builds were chaotic I had to disable -Werror and fix many issues
manually, then I had to fight with binutils assembler failing, I tried
4 different versions before I got it right... I did write a commit to
update the instructions but if you say that just downloading the stock
pre-compiled binaries worked I am a bit disappointed because the
instructions specifically told not to do so.

Yes, dfu worked right away, very nice tool.

Actually I'm wrong.
You did: *(skb->data + 1), which works.
I did: skb->data[1], which does not.
I thought that my mistake was related to data being a void *, but it's
a char * so both should work. I don't know why it failed, maybe my
attention level was too low and I missed something else.
