Obviously I would prefer to use NOCOPY since I only send "read-only data"
with the view to improve execution time and memory usage...
What you mean by read only data? It must be at least:
- directly adressible (flash or RAM in MCU),
- accesible by drivers DMA (for example Core Coupled RAM on STM32F4 cannot be used).
