2009-01-02Blackfin Serial Driver: fix bug - SIR driver stop receiving randomlyGraf Yang1-0/+24
Bug description: The IRDA receiver may can't receiving any more after processed some signals. To duplicate this issue is put three IRDA devices together, one blackfin, two none blackfin, they will detect each other. Let one none blackfin devices irdaping the blackfin devices, when it stopped print out ping information, it is the time that blackfin stoped receiving, the time is random. The related register bit is OK, the other devices is sending data continuously. But no interrupt come. Fixing: I tried Michael's suggestion that request the UARTx error interrupt, and reset the IRDA when found FE error. This method helps much, but it can't completely avoid stop. Reset the IRDA before every time sending the data is more safe.
