Q: How can we tell, via top marking, whether a MAX32660 device (MAX32660GWEBL+ or MAX32660GWE+) has the bootloader installed?
A: The distinction is made through the top mark on the device package. Devices with the bootloader installed include “BL” in the top mark, because “BL” explicitly indicates that the bootloader is installed. Devices without the bootloader installed do not include this indicator.
