Bare metal programming

Hello Aaditya

Mostly IDE's come with compilers. Is there is a specific compiler you are looking at for compiling the source code?

Hi,Thanks

Hello Aaditya,

You need a compiler and linker to be able to do so. Pretty complicated if you are setting it up outside of the IDE environment. Suggestion: Install an IDE

Hello Amit,

Why complicated Amit?

I've done precisely that with IAR tools, it didn't take long or require much effort. I've previously done that with gcc which took longer since i first had to figure out how to build the compiler which is a step that is less likely to be required.

And doing so beats trying to figure out the inanities of yet another IDE and getting it to accept any tools other than it's own. Or navigating the overwrought complexities of Eclipse (now that's the start of an editor war)

Now maybe CCS doesn't have the proper documentation to call a build process from the command line but other tool chains doq. IAR's was straight forward enough although the GNU documentation can be intimidating in its detail. I have, in my limited interaction with CCS, noticed that it's documentation appears a bit scattered but that may be a reflection of my limited familiarity.

I agree with the OP, this should be a straightforward task, especially for someone already experienced in the command line.

BTW, isn't CCS an Eclipse environment? My recollection is that the Eclipse heritage of CCS has caused me many problems installing the TI DSP compiler. Eclipse is dangerously close to collapsing under its own weight in my experience

Hello Robert,

"all I want to do is open cmd prompt, run some blinky.c on my board."

This does not suggest the poster experience...

Yes, CCS is eclipse based...

By CMD, I meant cross compiler tools. I downloaded and installed ARM GCC tool chain, I was able to compile the code and make an object file with right flags but am having difficulty with assembling and linking, I don't have .s file for TM4C, I could use .ld file for linking provided in blinky example. I don't know how to create one .s file.

I have not heard (and sorry for my lack of knowledge) but cmd prompt has never been associated as implying cross-compiler tools

I have always used the .s file in CCS IDE running GCC tool chain, so never worried about getting one or debugging one. Check on CCS forum and you may get some examples.

Thanks Amit! My bad. I should have put the question in a better way! 

Hello Aaditya

CCS has a console log which shows all the commands, options and flags being used during a compile and link

I just want to use Windows/Linux command prompt. Once I understand the flow/what tools are involved and the extensions.

Found Tiva, Linux, CMake where someone describes how to compile a Tiva program using GCC from a command line using CMake, and debug using Open On-Chip Debugger and GDB from the command line.

Thanks Guys,

Hello Aaditya

In CCS when you generate a new project within the IDE environment with GNU compiler the template and the startup file are auto-populated

Hi,

Cortex-Mx micros do not need startup.s files. Actually only Keil uses that, the others, CCS, GCC uses startup_ccs.c/startup_gcc.c file, to be found in examples folder of each micro.

Thanks Petrei,

Hi,

Yes, the file startup_gcc.c must be compiled also and then both/all files should be linked to generate the application. To do compilation/link automatically, you need to write a Makefile and then use the make application on your computer (make.exe on Windows, known good version 3.81).

I do not have an example at hand, must look into archives.

But also, in Tiva folder there is a Makefile, you can open a cmd window, cd to Tiva and call make - note this will compile/link all examples in Tiva, takes too long to accomplish. However, the makefile is interesting, since it have all configurations/switches needed. (The Makefile writing is usually avoided by IDE programs like CCS. Also in IDE you may use parallel compiling for large programs, but this is another story).  

Point taken Amit

Hello Robert

Which one?

Amit

All of them of course Amit.

But in this particular case the demonstrated experience level.
