Help needed to understand code

[Shubhangi Jadhav]

Hi,

	Could you please explain to me the complete flow, right from the beginning
of execution of the assembly code. How does the assembly code jump to the C
code ? which is the jump instruction in crt0.base that makes it jump to
c_start.S

Thanks,
Shubhangi

The bottom of crt0.base jumps to c_start.S using loader "magic".
c_start.S runs in ram in the C code address space.  crt0.base runs in rom.
