How do I enable external SPI Flash using TouchGFX Designer?

Hello,

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

Thanks.

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

Hello JohanAstrup,

The RVA15MD-NUC64B board (Ver 1.2) is ready to order from https://riverdi.com/product/1-54-stm32-nucleo-64-display-kit-wba65ri?srsltid=AfmBOoqty3C9VNFotaCoZj9u3363QisrQFmrcXd_7txdV15ge2dkPEDu but TouchGFX Designer 4.26.1 is not still ready to use 8MB external SPI flash.

Thanks.
