Hi, I have a custom board of c6678 with two ethernet ports.

I already use Port 0 on Core 0. ( QMSS + CPPI + PA + NIMU)
And I need to add Port 1 on Core 1.

What should I do?

can i get example code for dual Port/Phy Etherenet?

ps: my ccs version is: 9.3.0
ndk version: 2.25.1.11
pdk version: 2.0.15
bios version: 6.76.2.02

MyungJoo Lee,

Good day!.

>>>>>>>>I already use Port 0 on Core 0. ( QMSS + CPPI + PA + NIMU)
>>>>>>>>And I need to add Port 1 on Core 1....add NC_NetStart only on Core 1. NetworkIPAddr called, and NC_NetStart() return -1 .

As per the doc, I attached here --- > NDK, PA Resource Wiki for Keystone Devices - Texas Instruments Wiki.pdf

I extracted the following content

The NDK and NIMU based examples are designed to run on core0 by default. Yes, it is possible to load and run on the other core like core1, core2. But the NIMU driver and example code needs to be modified according to core on which it runs. There is no solution for running simultaneous NDK stacks on multiple cores. The attached code is based on "mcsdk_2_01_02_06" release.

Please refer to the attached code below.
