Ticket Name: RTOS/TDA2PXEVM: RTOS/TDA2PXEVM: Support for multiple NetworkRx link instances

Query Text:
Part Number: TDA2PXEVM Other Parts Discussed in Thread: TDA2 Tool/software: TI-RTOS Hi We are working on TDA2PX based Hw and vision SDK version is SDK_03_03_00_00 .Here , when we try to initiate two NetworkRx link in usecase for testing we want to send the image in one port and sensor data in another port, second NetworkRx link fails during the link creation time as below mentioned debug logs (attachment): … [HOST ]     15.723144 s: NSP GMAC: PHY 2 Found on MAC Port 0 [HOST ]     17.523851 s: NDK: Link Status: 10Mb/s Full Duplex on PHY 2 [HOST ]     17.723388 s: NDK: Link Status: No Link on PHY 2 [HOST ]     18.328951 s: NETWORK_CTRL: Starting Server (port=5000) !!! [HOST ]     18.328981 s: NETWORK_CTRL: Starting Server ... DONE (port=5000) !!! [HOST ]     21.123589 s: NDK: Link Status: 1000Mb/s Full Duplex on PHY 2 … [HOST ] 33.475660 s: NETWORK_TX: NETWORK_TX: Server listening (port=29172) !!! [HOST ] 33.475873 s: SYSTEM: ERROR: No link registered at link ID [68] !!! When we further debug the code then find that, we can have maximum one NetworkRx link objects as per below mentioned sdk source code vision/platform/ti/tda2/links_fw/include/links_fw/include/link_api/networkRxLink.h #define NETWORK_RX_LINK_OBJ_MAX (1U) Can we support for multiple NetworkRx link instances in existing code base ? what are all the changes needs to be done to enable this, Is there any specific patches required for this feature. Can you please support on this ? Regards, Raj

Responses:
Ti Raj Dual Ethernet port support was not available in VSDK 3.3 release. This is only supported with latest VSDK 3.6 (released on early Jan) please refer this link to download the same - www.ti.com/.../processor-sdk-tdax Mainly NSP package updated to support Dual Mac. VSDK also has some configuration changes and sample UC to support Dual Mac. you either move to VSDK 3.6 release or use the latest NSP package from 3.6. BTW, are you using both ports with static IP or dynamic IP config? we have an open issue for setting one port as static and other as dynamic IP. But both Static or both dynamic is functional.
