Program entry point

Hi m_fox,

> why it doesnot make from offset address 0?

Because your .text section is not in the same memory as your reset address.

Roughly speaking, if your .text _is_ in the same memory as your reset address,

system.h defines ALT_NO_BOOTLOADER. This in turn causes the reset code to

be included and placed in the .entry section. It goes like this:

-- The symbol "__reset" (and reset code) is located in section .entry.

-- The section .entry is located in the memory block named "reset".

-- The memory block "reset" has its origin at the system reset address.

There are a bunch of ways you could do this. I would probably just leave all

the automated stuff alone and add a small assembly module that jumps

to _start, that's in section .entry. Then just use objcopy to create the binary ...

so you don't have to create custom linker scripts, change syslib properties,

etc. etc.
