Hi Gurus, We have developed a QMC driver for MPC860P and the TX is working fine. We are getting interrupts for Tx, But, the RX we are not yet all getting any interrupt.
I am using the functionality for providing GCI(2 bits/D-channel, and a total of 8 such channels) support through SCC3 port of the MPC860P. The configuration of TSA Ram, and QMC Global/Specific parameters have been correctly done. Though I receive TX interrupts, I am not able to receive any RX Interrupts. This is strange because I can even see incoming physical data on the Rx port through a Logic Analyzer. I do not get any data in the receive buffers at all. The QMC initialization has been done in line with the example code provided from Motorola at: https://e-www.motorola.com/webapp/Download?colCode=MPC860COD05&prodCode= MPC860&nodeId=03C1TR046708718657&appType=license&location=psp I tried with loopback, but to no success. The basic doubt here is do we need any microcode for QMC on MPC860P. Thanks in advance!!! Best regards, Kondala ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
