iMX8QM QSPI Slave

jars121 — Thu, 04 Feb 2021 22:13:52 GMT

Hi,

I'm looking to interface an iMX8QM to an external MCU which provides a QSPI interface as the Master. I found this question from 2018 regarding QSPI slave on the iMX8QM, but have been unable to find anything in the documentation which states that the QSPI interface only supports Master mode. Is QSPI Slave mode possible with the iMX8QM controller? Any clarification would be greatly appreciated.

Thanks!

Hi jars121

>QSPI Slave mode possible with the iMX8QM controller

sorry it is not supported, in particular FlexSPI has not special master/slave setting like ecspi

ECSPIx_CONREG(CHANNEL_MODE).

Best regards
