I'm not able to ping another firewire card. Sometimes the card isn't even recognized. Is this a bug?</div> <div>Activating lock debug statistics and disabling SMP improves the problem but doesn't solve it. I'm just a beginner to kernel debugging. So I would be glad, if someone could help me.</div> <div> </div> <div><u>uname -a</u><br/> Linux am57xx-evm 4.4.41-gf9f6f0db2d #1 SMP PREEMPT Wed May 10 16:57:47 CEST 2017 armv7l GNU/Linux</div> <div> </div> <div> </div> <div><u>lsmod | grep -e 1394 -e firewire</u></div> <div>firewire_ohci 32959 0<br/> firewire_core 59859 1 firewire_ohci<br/> crc_itu_t 1669 1 firewire_core</div> <div> </div> <div><u>lspci</u></div> <div>00:00.0 PCI bridge: Texas Instruments Device 8888 (rev 01)<br/> 01:00.0 PCI bridge: Texas Instruments XIO2213A/B/XIO2221 PCI Express to PCI Bridge [Cheetah Express] (rev 01)<br/> 02:00.0 FireWire (IEEE 1394): Texas Instruments XIO2213A/B/XIO2221 IEEE-1394b OHCI Controller [Cheetah Express] (rev 01)</div> <div> </div> <div> </div> <div> </div> <div>Best regards,</div> <div>Sascha</div> <div> </div> <div> </div></div></body></html> |
