LPC4370 is a flashless part with SPIFI and SPI peripehrals sharing similar pins. It is necessary to use SPIFI to access external flash. Hence, the part could not external SPI devices (such as ATMEL ATWINC1500) . Do you have suggestion?
SPI interface in ATWINC1500 is for host interface and UART interface is for debug.
Thanks.
Thanks. I can use ssp1.
Hi HM Yoong,
In the LPC43xx, the SSP0/1 and SPI module both are able to interface external SPI device.
You can learn the more information in these chapters.

I checked again, SPIFI has a #SPIFI_CS pin. Has anyone try to use SPIFI/SPI with external flash and other devices, multiplexing external devices using CS pins?
Of course, program in the flash (assuming not too big) is transferred to internal RAM.
