TMS570LS3137: SCI with DMA , RX not working

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

Hi,

below is a mini project to test SCi Tx and Rx via DMA. Utilizing SCI, not SCILIN.

Tx via DMA worked . however Rx via DMA is never hitting the dmaGroupANotification().

In main() I am polling on a variable to be cleared by dmaGroupANotification(), to figure out if I received FRCNT amount of  bytes. (Block Transfer should be complete )

I also attached the project with halcogen files.

What am I doing wrong in case of Rx?

any help would be great. thank you in advance,
