[Xenomai] RTNet - how to setup rt_fec on IMX6Q (Xenomai 3.0.7)

["Stéphane Reichert" <sreichert@sepro-group.com>]

Hello,



We are trying to use the rt_fec driver for RTNet on a iMX6Q board.



I have patched the KConfig to add this driver on buildroot and it compiles
perfectly.



But now, I am not able to use it on our board (it works when I “rtping”
the loopback,

but it doesn’t work if I try to ping an external board).



Each time I try to use the device, the rt_ping command returns

“ioctl: Resource temporarily unavailable”.



The same occurs if I try with or without tdma.



To reproduce the problem, here is the initialization sequence:

# modprobe rtnet

# modprobe rtipv4

# modprobe rt_fec

# echo 2188000.ethernet > /sys/bus/platform/drivers/fec/unbind

# echo 2188000.ethernet > /sys/bus/platform/drivers/rt_fec/bind

# modprobe rtudp

# modprobe rtpacket

# rtifconfig rteth0 up 192.168.214.30 netmask 255.255.0.0 hw ether
00:07:AC:81:0

# rtifconfig

rteth0    Medium: Ethernet  Hardware address: 00:07:AC:81:00:5D

          IP address: 192.168.214.30  Broadcast address: 192.168.255.255

Linux :   4.1.46

Xenomai : 3.0.7



Did anyone face this problem (I found some similary issues, but they
didn’t solve my problem on rt_fec) ?
