Product Number: ADSP-SC835
I have the EV-SOMCRR-EZKIT board with ADSP-SC835W and I am trying to test EMAC using the EMAC example code.
While other examples code (like audio talk through ones) worked straigth out of the box, the EMAC examples gives me some error before the Debug even start:

I noted that the Debug can actually start if I remove one of these call (no matter wich one):
eMACResult = adi_emac_SubmitDescriptorListRx(hemac,0,emac_desc_rx,NO_OF_DESCS, true); CHECK_EMAC_RESULT(eMACResult); eMACResult = adi_emac_SubmitDescriptorListTx(hemac,0,emac_desc_tx,NO_OF_DESCS, true); CHECK_EMAC_RESULT(eMACResult);
But if both TX and RX descriptors submit are present, the debug is having trouble to load, even if (and I'd like to stress this out) the code never gets to run at all.
