QSPI transfers on MAX32630FTHR?

Hi, I'm using the mbed compiler online and can't instantiate a QSPI object for Quad SPI transfers. I believe the MAX32630 chip supports quad spi but perhaps the

https://github.com/ARMmbed/mbed-os/blob/master/drivers/QSPI.h

In mbed-os/drivers/qspi.h there is this line but I tested and DEVICE_QSPI is not defined and so the QSPI code never gets defined:

  1. if defined (DEVICE_QSPI) || defined(DOXYGEN_ONLY)

So, it appears the software for the MAX32630FTHR doesn't support QSPI even though I think the chip does.

Would you be able to tell me if it's possible to get QSPI transfers working on the MAX32630FTHR platform? The datasheet only references having multiple SPIs.

Thanks, Marc

Hi Marc,

QSPI capability still has not been supplied by Maxim and this was recently raised on GitHub:

Please track that issue and comment on it if you have something to add either technically or from a commercial standpoint. It does appear that Mbed Community member Lee Shen is working on this.
