With QNX drivers, one must be able to kill them and restart them.
After slaying the cpsw2g driver, I cannot restart it.
Here is what I do:
During boot up (this is part of the build file)
tisci-mgr
waitfor /dev/tisci 4
shmemallocator
waitfor /dev/shmemallocator 4
tiipc-mgr
waitfor /dev/tiipc 4
tiudma-mgr
waitfor /dev/tiudma 4
...
display_msg "Starting Networking ..."
io-pkt-v6-hc -d cpsw2g -p tcpip pkt_typed_mem=below4G
if_up -p am0
ifconfig am0 up
dhclient -m -lf /dev/shmem/dhclient.leases -pf /dev/shmem/dhclient.pid -nw am0
There is one issue with above: driver tiipc-mgr fails

Unable to access "/dev/tiipc" (2)
Maybe tiipc-mgr isn't really needed, networking works fine anyway. (I have used telnet on it)
The problem is here:
If I slay the driver, I cannot make it work anymore. Here is the log:

At this point, the console is frozen and I have to reboot
