TMDS64EVM: enet_icssg_tcpserver example seems to be broken with MCU+ SDK v08.06.00.45

Part Number: TMDS64EVM
Other Parts Discussed in Thread: DP83869, SYSCONFIG

I've been trying to isolate an issue running the enet_icssg_tcpserver example in the MCU+ SDK and I think it's broken in release v08.06.00.45.

Here is the output

==========================
ICSSG LWIP TCP ECHO SERVER

Icssg_handleLinkUp: icssg1-2: Port 2: Link up: 1-Gbps Full-Duplex

It does not subsequently handle the IF UP event thus doesn't assign an IP address so the example does not work as designed. Is this a known issue ? Is there a workaround ?

I have currently reverted to the 08.06.00.43 SDK (which does seem to work) but woud like to use the latest release.

Thanks,

Jon

    Hi Jon,

    I will try reproducing this issue at my end.

    Hi Jon,

    It seems this is not a driver issue but configuration issue.

    The user needs to set the packet pool config to required settings i.e. value to sum of all rx packets combined on bases of packets allocated in DMA config.

    You need to enable the option "Only Enable Packet Info Allocation" before configuring Packet Pool config.

    Default configuration should look like this:

    Hi Rimika,

    Thank you. I've checked sysconfig and can confirm although the settings for CONFIG_ENET_ICSS0 were as shown above, those for CONFIG_ENET_ICSS1 were incorrect. I've ticked 'only enable packet info allocation' as suggested and then changed 'large pool packet count' from 48 to 32. I can confirm the TCP server now works wth the modified MCU+ SDK 08.06.00.45.

    The file to fix is located at C:\ti\mcu_plus_sdk_am64x_08_06_00_45\examples\networking\lwip\enet_icssg_tcpserver\am64x-evm\r5fss0-0_freertos\example.syscfg . I have included the updated content below.

    Can you raise an internal problem report for this issue and confirm it will be fixed in the next release of the SDK ?

    Many thanks,

    Jon
