Hi,

I m actually trying to write a basic code which calls .c function into an assembly code.

I get the above error only for this program:

I checked in the objects folder for other codes as well...the difference being generation of  main.o file, i.e. it is not getting generated only for this code!. I tried changing the compiler version to V5.06 update 7 i get another error as below:

main.s(1): error: A1157E: Syntax error following directive
assembling startup_TM4C123.s...
compiling function.c...
function.c(9): warning: #1-D: last line of file ends without a newline
}
function.c: 1 warning, 0 errors
compiling system_TM4C123.c...
".\Objects\callcfromassy.axf" - 1 Error(s), 1 Warning(s).
Target not created.

Can you please suggest i could do, have been stuck with this since days , is this compiler related issue or am i missing out on something
