I have taken the 8260 MCC driver in HDLC mode published in the sourceforge.net as reference and trying to develop the driver for SS7 mode. The module is loaded sucessfully and tesing for TX/RX functionality in SS7 mode using random data through external loopback. It is receiving the data intermittently(very inconsistent). Sometimes the TX interrupt is occuring but the data is not received. I have checked the TX buffer using BDI debugger and found the data in the buffer, but not getting received on the RX buffer. All this are done only on the channel-0 and the other channels(2,4,6,....) are not working. It looks like the MCC itself is getting strucked when this happens and need to give a hardware reset to come out. I am trying hard but couldn't track down to the problem. Any pointers/sample code/inputs would be helpful for me to proceed, since I am really strucked up here and couldn't track down. I would also like to know whether I could follow the same logic/framework implemented in the 8260 driver or not. Expecting your help in this regard. Thanks & Regards, Mohan
