I'm trying to use SPI1 in master mode on a CYW920706WCDEVAL board to simultaneously send/receive data with another device.

The API documentation describes the wiced_hal_pspi_exchange_data(len, txbuf, rxbuf) function, which is forwarded to spiffyd_ExchangeData() in wiced_hal_pspi.h. However, it appears that function is not included in the SDK. A linker error is attached below.

Hi,

We could reproduce it our side. 

Seems like the linker is not updated as you said. We will check with the dev team and get back to you.

 

Thanks,
