Can anyone tell me what are the setting & steps to build a project using ride 7 software for ARM controller LPC2148 whose code is written in ASM (*.s OR *.inc) ? Can anyone also give me a demo ASM code for this LPC2148 Microcontroller ?

The error which i get while building the Project is like this......

Hi Deni,

It looks like you do not have a C file in your project.
Can you try to create a simple C file with just the following:

int main(void)
{
    while(1);
}

Add this file in your project, along with your startup file, and try to program this on your target.

Warning: The file should have a ".c" extension, but NOT ".C", as uppercase .C is handled as a C++ by gcc, which will make the link phase a difficult experience :rolleyes:

Best Regards
