[SC594] Linkport operation on EV-SC594-SOM board


I am trying to check the operation of Linkport's Stop DMA mode using the EV-SC594-SOM board.

EV-SC59x_EZ-KIT-Rel1.0.0 does not have a Linkport sample, so I modified the sample code

of Linkport_DMA_Example of ADSP-2156x_EZ-KIT-Rel1.0.1 and applied it to the SC594-SOM board.

Linkport0 is the transmitter and Linkport1 is the receiver.

Also, on the EV-SOMCRR-BRKOUT board, the terminals of Linkport 0 and Linkport 1

were connected with jumper wires.

I debugged with CCES 2.10.0 in this state, but DMA transfer is not performed.

LP0_CLK remains "Low".

The message "Transfer is done" is not output.

Could you please tell me how I can solve this problem?

Best regard
