Hi,

we tried using SPI1 instance. even for SPI1 we are getting false interrupt.

currently we are using SPI-DMA with PPI. I have mentioned steps of how we are using SPI3, below

1. SPI initialize in non-DMA

2. PPI initialize

3. SPI un-initialize

4. SPI initialize in DMA

5. SPI un-initialize

please help us how to solve this issue.

Hi!

It's only the deprecated SPI0,SPI1,SPI2 that are without EasyDMA.

SPIM3 must be used with EasyDMA.
