I have four Iris nodes and all are broadcasting (flooding the network)
a message. Each node after receiving a msg waits for a random period and
re-broadcasts the msg.
I noticed that after a few seconds the radio stack locks up and returns
EBUSY forever.
I put a few debug statements in RadioSend.send() (file =
RF230DriverLayerP.nc).
if( cmd != CMD_NONE || state != STATE_RX_ON || ! isSpiAcquired() ||
radioIrq )
{
FormatDbgStr("FAT : cmd=%d,st=%d,spAq=%d,rIrq=%d\r\n",cmd,
state,isSpiAcquired(), radioIrq );
return EBUSY;
}
The error log I got looked like this before the send failed.
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=5,st=5,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
FAT : cmd=0,st=7,spAq=1,rIrq=0
It seems that the state and cmd variable somehow get out of sync.
Other settings in makefile
CFLAGS += -DTASKLET_IS_TASK
I am investigating this further and would like to know if anyone has
experienced something similar
Thanks in advance.
