ippStsBlockStepErr
This status is a memory-layout check for block-based primitives. A step smaller than an 8-sample block cannot address all rows of the block without overlap or out-of-bounds access.
It is usually caused by passing a compact width where the primitive expects a row step, or by using the wrong unit for the step value.
Diagnostic focus
- Verify whether the step is measured in bytes, elements, or pixels.
- Check that the buffer really contains an 8x8-style block layout when the primitive expects one.
- Compare source and destination steps separately; one side can be valid while the other is not.
