Ticket Name: RTOS/TDA2: Hello World Example Blinking LEDs No Communication

Query Text:
Part Number: TDA2 Tool/software: TI-RTOS Hello, We're having issues running the NDK Hello World example for IPU1 that's included in NSP_GMACSW_4_15_00_00 and uses NDK_2_24_02_31. The software is running on a Vayu EVM and we're using PHY2 on the board. When we run the original example and connect the evm to a linux laptop running Ubuntu 14 the example runs correctly and we can ping it. We can also run the companion helloWorld.c client software successfully. When we connect the evm to a switch we're seeing the LEDs on the PHY2 (P5 on the board) light up and blink indefinitely until power-off. Once the LEds start blinking in this pattern ping or client software will not work even when connected back to the Ubuntu laptop. We've tried other switches as well as other embedded linux devices in place of the Ubuntu laptop and only the ubuntu laptop seems to work. What do the blinking LEDs mean? Once the LEDs start blinking only a power cycle will make them stop. Is there a way to reset something from the TDA and avoid a total power cycle? Thanks, Juan

Responses:
Hello Juan, Do you have 100Mbps sticker on RJ45 connector of your EVM? If yes, please check below note for this issue in VSDK TDA2xx user guide. The workaround is to configure remote end for 100Mbps.

Hello Prasad, There are no stickers on our EVM. Also when 1Gbps link is established it seems to work the same as 100Mbps link. Thank you

Hello, Can you please share use-case logs when you run the hello world application?

Hi Jmg65, We haven't heard back from you, I'm assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). Regards, Yordan
