I'm trying to use McBSP4 with an external CODEC which is a

In this mode, the BSP is purely the master of these signals.
What can it possibly mean to get Frame Sync errors in this case
(I'm reading from the external CODEC)?
FYI, my registers look like this:
PCR0: 0x00000f0f
RCR1: 0x00000040, RCR2: 0x00008041
XCR1: 0x00000040, XCR2: 0x00008041
SRGR1: 0x00000f07, SRGR2: 0x0000101f
Any ideas or help?
Have you set the right McBSP source clock? It's in DEVCONF1/2 registers.
Yes, the channel works fine, but I only occasionally get errant Frame Sync errors.
