Hello @zhusuce ,
Thanks for your post. When the programming script includes multiple steps such as a full-chip erase, blank check, byte-by-byte or page-by-page verification, CRC checks, security configuration, and reset delays, it is possible for the total programming time to reach 17s.
If you would like to reduce the number of steps to shorten the programming time, we recommend contacting our third‑party partner, PEmicro Support, for further optimization guidance.

Hope it helps and have a nice day.
