STM32L4R5ZI using OCTO-SPI without flash memory?

[AWitt.759]

Hi,

I'm using a STM32L4R5ZI and i want to use OCTO-SPI with my own hardware. 

My question is, can i use the OCTO-SPI without a external flash memory to communicate from the MCU to the PC ? Up to now i tried the provided OCTO-SPI example provided by STM for the STM32LR9I.

Thanks

Not sure where a PC fits in the equation, but QUAD or OCTO SPI should work fine into a CPLD or FPGA based state machine device.

Ok. Thank you for your answer.
