Hello,
Would it be possible to send a project that can reproduce this, so that I can test it and see if I can find a solution? Or do you mean that you found a fix for the issue?

Best regards,

Edvin

Hi, my problem is the same as the example code: when in SPIS interrupt handler we call the function used to "reset" (or update if you prefer) DMA (RX / TX buffers) the ECU tries to enter again in interrupt handler but the dedicated flag is clear before exit the first. I execute my SPI notification in background with a flag setting by SPIS handler

Hi,

I use the IRQ priority 7. But if I change to another (6) I have the same problem.

Hello,

It sounds like you have some IRQ priority collisions. What IRQ priority do you use on your SPI?
