S32K342 LPSPI3 Async Transmit for 64 byte frame having transmission issue

saginala_khaderbasha — Fri, 23 Jun 2023 06:24:53 GMT

Hi Victor,

I am using LPSPI3 in S32K342 and my requirement is sending 64 byte frame at once using AsyncTransmit and interrupt enabled. I am facing issue with loss of data exactly at 12th frame which contains CRC information in the frame sequence. Because of that the slave is not processing the frame and getting error. Kindly help me to fix the issue.

Thanks In advance,

Saginala Kahderbasha
