Thank you for your post!

The SmartDMA does not have a defined code size specification. For correct operation, each SmartDMA function module must be placed at a fixed memory address.

Installing SmartDMA firmware essentially consists of copying the code array of the SmartDMA function modules to a specified RAM address.

RAMX (up to 96 KB) is connected to the Cortex‑M33 code buses and is the preferred RAM region for code storage, including SmartDMA function modules.

Let me know if this information help.
