AWR1843BOOST: Can we use QSPIFlash driver API in mrr_18xx_dss?

Part Number: AWR1843BOOST


We are modifying automotive lab demo lab0007 mrr. The plan is: 

We want to add a configuration parameter. According to the value of this configuration parameter, program can selectively use function rangeBasedPruning(...)

We want to store this configuration parameter in QSPIFlash memory. Then we can change its value through QSPIFlash read/write.

Is it possible? Can we use QSPIFlash driver API in mrr_18xx_dss? 

Kind regards

    Hi Lei,

    Yes, this is possible with the qspiflash driver, but only from the MSS. Something like this is already implemented in the out of box demo to save and restore calibration data to/from flash. Refer to mmwDemo_flashRead, mmwDemo_flashWrite functions in the demo source code.

    Note that the library only works with MSS, so you will have to implement the QSPI read/write in MSS, and pass that information to the DSS core via mailbox.
