DMA transfer issue with ADC1 on S32K312

when using DMA to transfer ADC data register value, find that for ADC1, when enable the BCTU trigger, the SDDR of DMA channel is changedCapture.PNGso the DMA transfer is not working

Hello @LeoYang-,

As I discussed with you, I doubt that this issue can come from debugger. So, could you try to test with T32 debugger and let me know your result?

If you can't do that, could you try to test with different Optimization Levels?

Hi 

  currently we can not set the optimize level above none because it affect our normal function, but we did found how to solve it by correcting the DMA configuration, if we got the chance to test with T32, i will let you know, Thank you for your support!
