TMS320F280039C: USE CLB to Passthrough FSI RX_C and RX_D signal to others GPIOs (CLB OUTPUTXBAR)(Abnomal waves: CLB Output is not same as input)

Part Number: TMS320F280039C
Other Parts Discussed in Thread: TMDSFSIADAPEVM

Hello Every One!

I have some problems when use CLB to passthrough FSI signal.

Device: F280039C Launchxl Pad + TMDSFSIADAPEVM.

Config GPIO_54 as FSI_RXCLK, GPIO_52 as FSI_RX0. at the same time, Config CLB INPUTXBAR: the Source of XBAR_INPUT1 is GPIO54, the source of XBAR_INPUT2 is GPIO52.

Config CLB OUTPUTXBAR, Pin78 as CLB1 OUT0, Pin79 as CLB1 OUT1

The problems is that the CLB output is not same as FSI RX_CLK,we need some help to sovle this, or if this usage is allowed.

The figure yellow line is FSI RX_CLK, Green line is Passthrough signal use CLB internal
