Original question:

AWR2944EVM: SPI Internal Loopback

MCU-PLUS-SDK-AM273X: TPR12 EVM- led blinking

Part Number: MCU-PLUS-SDK-AM273X
Other Parts Discussed in Thread: AM2732, AWR2243, TIDA-020047

Tool/software:

Hi, 

I have the below board with me
https://www.ti.com/tool/TIDA-020047

It contains the SOCs AM2732 and AWR2243 and I have downloaded the below sdk:
https://www.ti.com/tool/download/MMWAVE-MCUPLUS-SDK/04.04.01.02

I tried running the led blinking example on the SOC AM2732 and in the core r5f - nortos



But the led is not blinking as the mentioned in the:
https://software-dl.ti.com/mcu-plus-sdk/esd/AM273X/08_02_00_26/exports/docs/api_guide_am273x/EXAMPLES_DRIVERS_GPIO_LED_BLINK.html

(MSS_GPIO26) Because I don't have the exact AM273x board(maybe)..

What are all the extra configurations do I need to make to make the led glow in my board?

Thanks and Reagrds,
Niranjana A

    Hi Niranjana,

    TIDA-020047 does have AM273x SOC on the board, but it is different board as AM273x EVM. The LED blinking example of AM273x MCU+ SDK is designed for the AM273x EVM. That is why the example runs on TIDA-20047, but no LED blinking.

    Best regards,

    Hi Ming, 

    Thanks for your reply..

    I would like to know whether it is possible for me to run a LED blinking example on the TIDA board...

    I would also like to know the schematic or datasheet or technical reference manual for the board..

    What is the generic difference between the EVM board and this TIDA board of TI?

    Also, I tried running the SPI loopback example.

    The result is passed..How does it work if this is a different board?

    Thanks,
    Niranjana A

    Hi Niranjana,

    The LED blinking example in the AM273x MCU+ SDK 09.02.00.51 is using the MSS_GPIO26 to control the MSS_GPIO_2 (LED) on the AM273x EVM. On the other hand, TIDA-020047 does not have such LED controlled by the MSS_GPIO26, therefore the example will run without error, but no LED will be blinked.  The difference is not the SOC, but the boards.

    Best regards,

    Ming
