Hello,
I have to continue debugging the RTnet dm9000 driver which was
under development previously. It's about the chip aside the PXA270 on
Toradex & Mobisense platform. The threads were inside
http://thread.gmane.org/gmane.linux.real-time.rtnet.user
Most parts of the works have been done on alignment problem
(2010-07-19) and Internal error : Oops (2010-03-30).
Here, there are some remaining bugs to figure out.
The initialization has been done by loading modules and rtifconfig,
rtroute. (tdma configuration seems not really fully working though
with "rtnet start").
r...@mbs270:~$ rtifconfig

Real-time PING 10.0.0.1 56(84) bytes of data.
ioctl: Resource temporarily unavailable
The error in dmesg:
hard_start_xmit returned -11
What could cause that problem ?
So, how to deal with the ioctl problem in rtping -> rtdev_xmit (rtdev.c) ?
Thank you for your help
