Run ndk helloworld example on Eth0

aloras

Hi,

I have a custom board on which eth0 is used to communicate with external. I try to port "ndk helloworld" example project under mcsdk directory to my environment. Unfortunately I cannot change just the ethernet port used from 1 to 0 in the example. Can anybody give some information about this issue? I want to use the tcp/ip stack ndk for ethernet0.

Hi,

Which DSP device you implemented on your custom board keystone1 or keystone2? Also provide your DSP part number.

Take a look at below thread for two ports enabling.

Thanks,

I presume that its C6678.
By default, EMAC1 is connected to 1GbE port through PHY and EMAC0 has been routed to AMC connector on C6678 Shannon EVM board.

Also, NDK doesn't have a support for EMAC0 port but you can use the following link to enable.
As current NIMU driver implementation, please note that you can enable either EMAC0 or EMAC1 at a time and not the same time.

Hi,
Have you tried the previous attached code ?

Thank you a lot. It seems OK. But when I run the code I have observed "Verify_Init: Expected 0 entry count for Queue number = 897, found 2 entries" message on console. When I inspect the nimu source code I see that there is a "Verify_init()" function which verifies that everything is correct for queues. But it seems to me normal to find 2 entries for the queue number 897. Because 16 decsriptors are used for tx, 110 descriptors are used for rx. At the beginning there are 128 descriptors. So what is wrong with this?
