hello,
I need to make the communication wireless between a master and slave with the
experimental hardware rt2500 .
i do the configuration of the ralink rt2500 card with this steps:
1. I remove the non-realtime network card's device drivers and modules (rmmod
8139too, rt2500).
2. I load the RTAI modules (rtai_hal.ko, rtai_lxrt.ko, rtai_sem.ko,
rtai_rtdm.ko).
3. I load the RTNET modules (rtnet.ko, rtipv4.ko, rtpacket.ko).
4. I load the rt2500 card drivers realtime (rt_rt2x00core.ko, rt_rt2500pci.ko,
rt_loopback.ko).
5. I configure the rtwlan0 interfaces with rtifconfig and rtiwconfig.
I can do "./rtping
<IP_ADDR_LOCAL>" to ping the local loopback successfully, when i call "lsmod"
, i find the realtime driver of the network card in the loaded module list.
But when i want check the communication between the nodes an i run "./rtping
<IP_ADDR_SLAVE>", the system crashes and i must restart the computer also when
i want to make the configuration of the routing table with "./rtroute solicit
<IP_ADDR_SLAVE> dev rtwlan0" the system crashes.
I do not know what is the problem or i am wrong because with this steps the
communication in the wired network with RTNET working properly.
Thanks for the help!!
