Hi,
I have a program that takes up about 64K*3 flash space; but when I burn it into Teensy4.1
using teensy-loader/halfkay, it seems that more than the necessary amount of sectors are erased.
How does halfkay determine what needs to be erased prior to burning in the new image?
I ask because ideally I'd like to be able to update my bootloader but not erase all the other
sectors when doing that. I notice that sectors just above the bootloader are erased, but
then sectors up near the top are not.
