Hi ppl. I have discovered very very odd problem with SMC2 on my 8260 board. kernel version is 2.6.17.
The board is 8260 with serial ports on SMC1 and SMC 2 (SMC1 - console) Now if I use SMC2 for communicating with remote device, ( some protocol) I am sending packets and wait for a response. However if the packet I send is SMALLER than 5 bytes, SMC goes completely crazy. write() doesn't return error, but the next read() hangs completely, and the process moves to D state and it is impossible to kill it by any means. It only happens when consequent writes of smaller than 5 bytes. I tried to check the driver, but couldn't find any clues to what goes wrong. I tried both compatibility and platform-based modes with the same results. Any help on the issue would be highliy appreciated. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
