Hello,

How do I enable 8MB external SPI Flash on the WBA65+RVA15MD using TouchGFX Designer?

Thanks.

Hello @JDeit.2.

The external flash is not enabled in the TBS because the pinout on the morpho connector of the NUCLEO-WBA65RI does not match the Riverdi RVA15MD. SPI is unavailable on any set of pins where the external flash is connected.

Riverdi is currently developing a new version of the display expansion board (REV1.2) with a pinout that supports using external flash on the NUCLEO-WBA65RI. However, this board is still in development and not yet available for purchase. Once this board becomes available, the TBS will be updated to support the 8 MB of external flash.

Best regards,
Johan
