[GHRD] EMAC1 in Peripheral Mux

Hello,  

 

1) Is the GHRD ghrd_5astfd5k3 compatible with the ArriaV SoC Development Board? 

 

2) According to the GHRD ghrd_5astfd5k3, some of GPIOs are selected instead of the EMAC1 ports in the HPS Peripheral Mux (e.g. GPIO17 instead of EMAC1.TXD2, GPIO18 instead of EMAC1.TXD2, etc - please see below the shortcut). So, how the EMAC1 can work if some of its ports are disabled (GPIOs are used instead of them)?

Thank you!

Looks like this 5astfd5k3 that you openned is 14.0 GHRD for Arria V already.. 

 

You are right, this looks not going tp work..how ever i think most of the emac design example are in cyclone v which is already enabled those pins for utilization, i open up for cyclone one all with emac pin selection. did you tried open some of the design example say for cyclone V?

No, I just tried this GHRD, which was recommended by the local FAE...

maybe consider to download a cyclone V one and open it for verification.

OK, thanks, will do it... Anyway, it will be very strange if GHRD contains any errors... I believe thunders of user look into this GHRD...

I would say the hps emac this is not implemented for in Arria V probably as so far most design example is in cyclone V. :D

This is one of the emac with cyclone. Maybe suitable for your reference? 

 

Sorry no bare metal version.

By the way any guys/visitor around may share of there is possible design example that is using Arria V as the base?
