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.
