FAQ:
1. Why does it keep scrolling through 0x****** and len******? This is because the built-in S2 Marauder in the Little Dolphin is not consistent with the current version of our module. Just refresh the firmware in our module. Currently, the firmware mntm-007 Chinese-20241010 is the 1.2.1 version Marauder firmware.

How to program firmware when firmware refresh crashes?
