RE: [microblaze-uclinux] slow performance on XUP V2P
Hi,
Thank you all for the inputs. I've enabled the Icache and Dcahce. Now the BogoMIPS is 49.7, and the "ls" responses ok. But the ping delay is still 7ms, which I think is very long time for a point-to-point Ethernet. The DMA on the EMAC should have been enabled (see the bootlog).
Cheers
Deli

These delays are typical when you don't have the microblaze caches actived.
