Porting Wifi qca_demo from FRDM-K64F to TWR-K64F120M

[gustavocosta]

Hello there,

I'm trying to port the qca_demo from the FRDM-K64F  to work with the TWR-K64F120M. I tried to follow the document AN11981 - QCA4002/4 KSDK Porting Guide (https://cache.nxp.com/docs/en/application-note/AN11981.pdf?fsrch=1&sr=1&pageNum=1) but the difference was too big, and I could not make it work.

For instance, I'm using MCUXpresso IDE; KSDK 2.2 for TWR-K64F120M; and SX-ULPAN-2401-EVK.

Also, when I plug my SX-ULPAN-2401-EVK with the TWR-SER, the orange LED (green +red) lights up, which means "Power supplied but SX-ULPAN powered off" accordingly with Sílex product specifications. Is there any conflict between these two boards? 

Any tips to follow that would get me through it?

Thank you very much.

Hi,

The MCUXpresso SDK V2.2 for TWR-K64F120M provides the board initialization code, customer could use this software package as the porting software platform.

Customer need check the pin muxing to select  the correct K64 pins via SPI interface communicate with QCA4002 modules.

About the SX-ULPAN-2401-EVK board conflict with TWR-SER, customer need to check with Silex.

Below is the Silex support info:

For TWR-K64F120M board provides OpenSDA virtual serial port, customer doesn't need TWR-SER for COM communication.

Have a great day,
Ma Hui
