Vaibhav, Thanks for the reply. I have selected intenal clk sources for both ACLKXCTL and AHCLKXCTL ACLKXCTL=0x00000061 AHCLKXCTL=0x00008033 PDIR=0x0A000000 ACLKX1 is not produced. The above settings should produce ACLKX1, so that GBLCTLX can be set. Am I correct? What are the other checks to be done, so that ACLKX1 is produced? Pls reply

Since you want to use AHCLKX1 as master clk for another device I suspect the ACLKX is not already running. If you don't have ACLKX externally generated you need to select the internal clk source in ACLKXCTL (and possibly even in AHCLKXCTL - depends on the use case) before GBLCTL is programmed.

But I am not able to set GBLCTL. for port 1 bit= 1<<9; bit &= 0x1f00; mcasp_port[port].mcasp_vregs->gblctlx |= bit; while ((mcasp_port[port].mcasp_vregs->gblctlx & bit) != bit); It does come out from the while loop. But for port 0 no such problem.
