    Hi Fawad, I checked the McASP pins using oscilloscope. These are my findings. 1. There is no data from pins AXR1[0], AXR1[1], AXR1[1],AXR1[10](Rx pins) and AXR1[5],AXR1[6],AXR1[7] and AXR1[8](Tx pins). But AHCLKR1,ACLKR1,AFSR1, AHCLKX1,ACLKX1,AFSX1 are clocking. 2. If I copy sine tone into the...
