I tried to tweak them to do full-duplex transfering but failed with wrong data.</P><P>I am wondering if there are full-duplex EDMA transfer examples?</P><P>&nbsp;</P><P>Regards,</P><P>Yanfeng</P> Thu, 23 Jun 2022 02:12:14 GMT https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/Full-duplex-LPSPI-transfer-with-RT117x/m-p/1477803#M20207 yfliu 2022-06-23T02:12:14Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/Full-duplex-LPSPI-transfer-with-RT117x/m-p/1478887#M20247 <P>We've solved the issue by aligning the wiring cable well enough.
