HI Yuta,

What all modification you have done to the code ? Are you checking the PHY alive status register after calling MDIOInit() function? The register will be reflected with proper value only after MDIO is initialized.

Hi Sujith,

No modification I have done to the code. Therefore, I check the PHY alive status register after calling MDIOInit() function.

Don't I need to modify "lwipopts.h" and "opt.h"?

Any ideas?

Regards, Yuta.

Hi Yuta,

No need to modify lwipopts.h and opt.h. Is the prebuilt binary for enet_echo in the package working ?

Sujith.

Pre-built binary for enet_echo is working well. But, example code is not working.

I created new project in CCSv5 and configure include path. Then, I modified SECTION .text and .bss into DDR0 from L3OCMC0 at "AM3358.cmd". Because the error #10099-D was outputted. This error says "run placement fails for object".
