calling an assembler fonction from c program

"and this warning came without any assembler code in my programm."

The trouble is, you have convered your entire project to assembler.
This means that the Linker doesn't know that it should be a 'C' project, and doesn't automatically include the necessary 'C' runtime support.

If you search for those messages in the knowledge base, you will find more detailed descriptions.

"what can I do for this?"

Don't convert the entire project to assembler!

Have just one file that contains the "skeleton" for just one function, and apply the SRC directive to that file only.

the one that works for me when doing 'funny stuff' mixing C and assembler

void assembler_main(void)
void main(void)
{

assembler_main():
}

with that you can - when you FULLY know what you are doing - have C calling assembler and assewmbler calling C

sir erak

you give good idea for simple code

i do assssemblery code in startup go call c from that

main is not need you know it is only convention

you want i give you sample????

main is not need you know it is only convention
it IS, unless you code assembler from scratch. The 'assembler' generated by the SRC still depend on all the C 'amenities' that startup and the next 'automatic', the name of which I can not think of right now, create.

sir erac

it IS, unless you code assembler from scratch

you is wrong you be know!!!!

startup has line

                LJMP    ?C_START

this is be line to calll main

remove ?C_START you no need main

you caall can then

                LJMP    any_asm_or_c_function_you_be_wanting

i know you see i try and workk well

you now want me send yo sample code to see?????

i not want money from friend erac for code!!!!

Modifying the startup code to jump to an application completely written in assembler does not make sense.

you is wrong you be know!!!!

If I am then why does what I have work and yours not?

DO IT

what is your problem trying a simple thing that will take you 5 minutes instead of discussing this for hours?

"Modifying the startup code to jump to an application completely written in assembler does not make sense."

why you not think so?????

if appplication is all assemblere you must break in modules

i told it is good structuure you know more modules

begin module is startup

but i not say all assembllerer!!!!!

you call assembleerc in start and c in any order i say

plz think consept is good!!!???!!!

sir erac

sorry

i sit in corner wear my hat and think good

I am sorry, I have made the mistake of responding to what you asked him
