Hello iceice,
Please provide more information about the context of the error. It would help to know:
- The RSDK release version.
- The rangeFFT kernel in question.
- The arguments passed to the rangeFFT kernel.
- The SPT command that actually fails (it is latched in the SPT registers when such an error occurs).
- The SPT command sequencer error register flags.
The DMA error can be caused by a number of things, such as when an invalid memory address has been supplied as argument to the kernel or if the memory is not initialised. We need to know more about the context to determine why the error occurs.
Best regards,
Gary
