CC3220MOD: Capturing NWP logs

Part Number: CC3220MOD
Other Parts Discussed in Thread: UNIFLASH, CC3220SF

Hi community,

I have followed the instructions found here: http://processors.wiki.ti.com/index.php/CC3120_%26_CC3220_Capture_NWP_Logs

But I don't get any output. I'm using the LAUCHXL board connecting the P.62 to the J5 (on the side of the TM4C129), expecting data on the first uart of the XDS110.

Application built in debug and loaded via UniFlash.

Am I missing something? Is there an example project for that?

Thanks in advance !

    Hi,

    Which P62 are you using? There are two launchpad header pins that are labelled P62, but only one of them has the required 0ohm resistor to connect to the CC3220 package's pin 62. Are you connected to the P62 pin on the leftmost debug header on the Launchpad, on the same column as 3V3 and directly above P01 and P02?

    Assuming you have added the required code to CC3220SF_LAUNCHXL_initGeneral(), the NWP logs should start being output as soon as the device starts up, as the bootloader will output some logs through the NWP log output. I would check your serial terminal settings to ensure you have the right settings. Do note that the baudrate of 921600 is different from the default that our SDK applications use.

    Regards,
    Michael
