SPI DMA example on ADSP-21569 is not working.
Hi,
We are trying to build and run the example code given for SPI communication in DMA mode, present at:
"<installation Path>:\Analog Devices\ADSP-2156x_EZ-KIT-Rel1.0.1\ADSP-2156x_EZ-KIT\Examples\drivers\spi\SPIDMAMode"
But, on running the code, the Tx and Rx are configured, but there's no communication from Tx to Rx.
The callback doesn't invoke the Rx event, i.e., RxCount remains '0', while TxCount = 4, as shown:
The connections on the EI3 interface (J2) are as shown(connected as mentioned in the attached ReadMe guide/ EZ-Kit Schematic).
Is there anything that I'm missing? Any help on this will be appreciated.
Thanks in advance,
Likhitha.

Hi Likhitha,
We have tested the SPIDMAMODE example project from BSP installation path in ADSP-21569 EZ-KIT. It is working fine to us. Please refer the attached image for your reference
From your screenshot, it looks like you wrongly connected EI3 interface in P9 port of ADSP-21569. As per the ReadMe guide/Ez-Kit schematics, you should connect it in P7 port. We suspect it might be the cause of issue the issue.
Hope this helps
