Cortex M4 Firmware

[wild]

Please take care that I have never used your processor!
According to http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0552a/BABIFJFG.html (it is the same for all Cortex Mx families) the first two 32bit words of the vector table are:
0x0000: Initial Stack Pointer value: points to a RAM area
0x0004: Reset vector: points to the code you have to start to run.
so, if I take a look at the binary dump of the file you uploaded:

000000 - 10 00 7F 01 00 48 60 00 F4 F1 FF FF 00 00 00 20 
000010 - 99 72 00 00 CD 72 00 00 21 74 00 00 21 74 00 00 
000020 - 21 74 00 00 21 74 00 00 21 74 00 00 21 74 00 00

beacuse the values ar written in little endiand format,
it seems your stack pointer points to 0x017F0010 and
the reset vector (code execution) starts at 0x00604800

It seems that your code is not loaded at the start of the flash, but in some other pages, so in IDA you have to tell that your code has an offset value different from 0.
It can help to take a look at the other vectors in the table to get some ideas in which part of your memory your code is loaded...
Now it is very late (02:30am) so I can't dig deeper.
If required, tomorrow I will check in more details in which memory page of your microcontroller this piece of SW is loaded.
Please let me know.

P.S.: I suggest you to take a look at the memory map of your micro.
