Honored ContributorSGDMA Interrupt
Hi, I'm having a major issue with the SGDMA component - the callback function that I've defined does not run. I'm not sure whether my code is flawed and I'm not calling the ISR function correct...

Honored ContributorOk update on the problem - I've tried to write some values (with the cpu) into the SDRAM to check if the SGDMA actually accesses the memory at all. When I try to read these values, I get sent to the exception stack. I have a feeling that the SGDMA is causing problems with the memory (both on and off chip).
How should I connect the SDRAM to the SGDMA to avoid this problem and successfully write to memory?
