C6474 EVM client example IP address question

Hi Josh,

It is possible. But did you convert the project from CCSv3.3 to CCSv4? 

Thanks,

Arun

Yes, I have converted the project from 3.3 to 4.1.2, and it seems to be working on Core 0, I am just unable to even ping the other two cores.  (I tried the same test usind DHCP, and had the same result - could ping core 0, but not the other 2)  Here are the modifications (snippets)  to client.c:

char *LocalIPAddr0 = "192.168.199.217";                  // Set to "0.0.0.0" for DHCP
char *LocalIPAddr1 = "192.168.199.218";                  // Set to "0.0.0.0" for DHCP
char *LocalIPAddr2 = "192.168.199.219";                  // Set to "0.0.0.0" for DHCP

corenum = CSL_chipReadReg(CSL_CHIP_DNUM);

        if (corenum == 0)
            NA.IPAddr  = inet_addr(LocalIPAddr0);
        else if (corenum == 1)
            NA.IPAddr  = inet_addr(LocalIPAddr1);
        else
            NA.IPAddr  = inet_addr(LocalIPAddr2);

...

so, each core comes up successfully, and here is the console printfs for each core:

CORE 0

-----------------------------------

TCP/IP Stack Example Client
Core Number on which NDK is running = 0
Since EFUSE MAC address is Zero we use the MAC Address = 00-01-02-03-04-05
Only on CORE 0: SGMII reset successful........
Only on CORE 0: SGMII config successful........
Only on CORE 0: SerDes should be up and running
EMAC has been started successfully
Registeration of the EMAC Successful
Network Added: If-1:192.168.199.217
Service Status: Telnet   : Enabled  :          : 000
Service Status: HTTP     : Enabled  :          : 000
Link Status: 100Mb/s Full Duplex on PHY 1

CORE 1

---------------------------------------

TCP/IP Stack Example Client
Core Number on which NDK is running = 1
Since EFUSE MAC address is Zero we use the MAC Address = 10-11-12-13-14-15
EMAC has been started successfully
Registeration of the EMAC Successful
Network Added: If-1:192.168.199.218
Service Status: Telnet   : Enabled  :          : 000
Service Status: HTTP     : Enabled  :          : 000

CORE 2

------------------------------------------

TCP/IP Stack Example Client
Core Number on which NDK is running = 2
Since EFUSE MAC address is Zero we use the MAC Address = 20-21-22-23-24-25
EMAC has been started successfully
Registeration of the EMAC Successful
Network Added: If-1:192.168.199.219
Service Status: Telnet   : Enabled  :          : 000
Service Status: HTTP     : Enabled  :          : 000

But then Cores 1 and 2 do not respond to a ping request.

Thanks,

Josh

Hi Josh,

Can you sniff the packets. It might be possible that we have to add MAC entries statically in the PC. Also please check the project using CCS3.3 and see whther you can ping all the cores.

arun.

That was it, thank you!  The packets were not being sent, so I had to add the MAC addresses using arp -s.  Now it is working in both CCS 3.3 and CCS 4.

The issue I see now though, is that only Core 0 responds to ARP requests - is there something I need to configure in the NDK to get the other cores to respond as I am not sure if adding them statically will be a feasible solution.

Thanks,

Josh
