boot loader entry point

John Fisher

Studying the source for the C55x C library, I came to the conclusion that it made sense to use a -e _c_int00 option to hex55 for a second stage boot loader that links the C library. However none of the examples I have seen go to this trouble. In the absence of a -e option how does hex55 set the entry point?

_c_int00 is the default entry point

Actually I think strictly speaking the answer is that hex55 will use whatever the linker sets as the entry point, which is _c_int00 if -c or -cr has been used to the linker. It doesn't say that anywhere in the hex55 chapter of the assembly language tools doc, but that would make obvious sense.
