Hello: I have a problem with a SPEAR 320 SOC board with kernel 2.6.27,using the spr_can driver and only sysfs for config: The board uses CAN0 and has only one other device on the bus. I can transmit and receive fine for about 20 minutes, transmitting at 75 hz. at this point the tx quits and returns with No buffer space available. candump shows that the tx has stopped transmitting completely but the rx works fine. I am using different tx and rx sockets ,dont think that should matter. Candump shows the received messages getting through fine, but nothing for tx. Obviously the bus remains up sysfs status does not show any problems. Also if I bring Can0 down and back up again, it flushes the buffers and everything works ok for another several minutes. I have tried increasing tx queue len and it does not help at all. Any ideas? problems with the driver? This sounds much like problems others have reported with other drivers.
Thanks , Chuck Hermann -- View this message in context: http://old.nabble.com/SPEAR320-SOC-TX-problem-tp31748715p31748715.html Sent from the Socket-CAN Users mailing list archive at Nabble.com. _______________________________________________ Socketcan-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/socketcan-users
