SYS/BIOS

Hi Awais Aslam,

Can you please answer a few questions about your set up?

1. Which hardware platform are you using? 
2. Which version of SYS/BIOS? 
3. Which version of CCS?

Awais Aslam said:

I am facing a problem related to SYS/BIOS RTOS. which is giving error like "source not found"   0c_int00_noargs() at boot_3.3.c:124 0x0a71a.

This is normal.  You should either see a button that is labeled "browse" (for the source file), or "view disassembly."  If the code where the PC is at is code that was built for debug then you will be able to open the source file and step through it.  If it was not built for debug (e.g. the PC is at the code of some non-debug library) then you will only be able to see the assembly code.

it does not print Hello word on console window.

Did you try looking in the "printf logs" window?  You can open this in CCS (assuming you're on CCSv4 or CCSv5) under the menu "Tools -> RTA -> Printf Logs"

Steve

thanks Steven for your kind response. I tried your suggestion but again I did not get any value in printflog window.

I am using EM-cc4306137-900 board 

code composer version is 4.2.1.

SYS/BIOS version is 6.32.03.43

XDC tool 3.22.02.27

Hi Awais Aslam,

Thanks for the info.

I just want to confirm that you are working with the SYS/BIOS hello example.  Yes?

Can you try reloading the program and putting a break point at main() in the example, at the following line?

 System_printf("hello world\n");

Do you ever reach the print statement?

It may also help to zip up your entire project and attach it to this thread.

Steve

Thanks Steve. Let me put this question in another way.

I have installed the code composer V5 now and debug a simple "hello world" example using EM-CC430F6137-900. I faced the same problem again as I told you before. According to your instruction I put a break point in my main code and I have checked the disassembly and then I came to know that pointer could not go into printf section in the disassembly window. Now please tell me what is the reason behind it and how can I fix this this problem. Waiting for reply. Thanks in advance.

Hi Awais Aslam,

Can you please zip up and attach your project to this forum thread?

Thanks,

Steve

I have uploaded the zip file of my project.

4377.workspace1.rar

Hi Awais Aslam,

Thanks for attaching your project; I was able to inspect your program and I think the reason that you are having problems with SYS/BIOS is because you have not enabled your application to use SYS/BIOS.  In order to use SYS/BIOS, you need to have a RTSC enabled CCS project that contains a *.cfg configuration file.  You also must call BIOS_start() from within main().

Have you seen the SYS/BIOS Getting Started Guide that came with your installation?  I think this guide will be very useful to you and I highly recommend that you read through it and try out the examples in it.

For example it's here on my machine:

C:\ti\bios_6_33_01_25\docs\Bios_Getting_Started_Guide.pdf

Hi Steven,

I'm also facing the same issue : No source available for "0x800000"  .

Am using the TMS320DM8168 EVM board.

I followed your suggestions from this post but am not getting hello world output on console.

It is showing the no source code available .

Please comment on my post...

Studinstru,

Glad that you solved your issue  (as noted here: http://e2e.ti.com/support/embedded/bios/f/355/p/212474/752030.aspx#752030)

Steve

Hi,

Sorry for late reply. I tried your suggestion but did not get any value on console window. I get the value in printflog. please tell me why I do not get any value on console window. Is this because of Jtag. Did I need UART to get value on console window.

Hi Awais,

See if you are running the available examples of sys /bios then you have to follow the mentioned instructions.

For printing the printf statement on console add #include <stdio.h> ,and after this printf statement write fflsuh(stdout);

I did like this and I got the result.

Hope so It will resolve your issue.

@Steven,

Though I'm able to run the existing code of SYS/BIOS in CCSv5.1,

But for running "Typical"Prject in ccs,

I got the follolowin error like 

Can't find a source file at "/db/vtree/library/trees/avala/avala-p52x/src/ti/sysbios/hal/Hwi_stack.c"
Locate the file or edit the source lookup path to include its location.

Pointer is heating the main function but If I will debugg simultaneously by F5 or F6 ,The above error message is coming on console.

What is the reason behind this ???

If you want I will start the new thread with this question ...

Please do the reply.

Hi Studinstru,

I tried to run the code as per your instruction but could not find any value in the console window. I am using EMCC430F6137RF900 board which is attached to my laptop through MSP-FET430UIF USB debug interface. Does this Debug-interface support STDIO applications.

Are you sure that you have loaded your application onto the DM8168 yet?

This is the starting address typically shown before you have loaded a program.  When you do a CPU reset, the PC will be here.  Since there's no source file, that's why you would see that message.

This is coming from the console?  Can you please make a screen shot and attach it to this thread?

I suspect that this is only due to the BIOS libraries being built for release mode.  You may be able to make it go away by configuring your application for debug in your *.cfg file.

Steve

/Awais,

How is your BIOS application configured?  Is it configured for xdc.runtime.SysMin?

Are you calling System_flush() after your System_printf() statements?

Steve

Hi,

How can I check the configuration. I only know that I have seen xdc.runtime in my project when I checked a*.cfg file. when I include System_printf() and System_flush() in my code I got the following error.

>> Compilation failure

undefined first referenced

--------- ----------------
System_flush ./task.obj
System_printf ./task.obj

I'm a bit confused by this... I thought you mentioned previously that you had tried a SYS/BIOS example which had System_printf() in it and you were able to get the output, albeit in the printf logs window?

If you don't plan to make print calls from Hwis or Swis then you can change your app to use SysStd (please refer to the XDC tools documentation on xdc/runtime/SysStd for more info. It's available in your CCS help)

Awais Aslam said:

You can check the configuration within CCS (the *.cfg file is the configuration).  When you use XGCONF to view a configuration, there's a "source" tab at the bottom of it that allows you to view the actual code of it.  Or you can open the *.cfg file in a text editor (please see screen shot below).

Steve

Hi,

The code which I have tried and get value in printflog window is given below. Steve I did not get any value "Hello world"on the console window. I tried SYS/BIOS example and simple hello world example without SYS/BIOS but could not make it. I am using EMCC430F6137-900 kit and connect it to my PC with MSP-FET430UIF debugger. Does JTAG support printf command using CC430 microcontroller.

Awais,

The test you are running does not output to the CCS console, but the output goes into a Log buffer that can be viewed either with the RTA log viewer, or the RTOS Object Viewer tool.  There is a comment in the file indicating how to see the output via the log viewer:

* All output is routed to a log buffer which can be viewed
* using the RTA "Raw Logs" viewer. After loading and running
* the application, launch the Tools->RTA->Raw Logs tool to
* view the logs.

Regarding the linking error when you added calls to System_printf() and System_flush()… I think maybe you didn’t add the include of the System.h file, like this:

#include <xdc/runtime/System.h>

There should have been a couple build warnings too, indicating the functions were being declared implicitly.  Was that it?

Thanks,
Scott

Thanks this time I got the result on console window but why I can't get the result when I run simple program without SYS/BIOS. I am sending you the code as given below. I did not get any result on console window for the following simple program.

#include <stdio.h>
/*
* hello.c
*/

void main(void) {
printf("Hello World!\n");
fflush(stdout);
}

Hi Scott,

Thanks Scott. I got it when I was running simple hello word example. when I tried to print something on console window using RF example using CC430F6137RF board, I got nothing. Could you tell what is the reason behind it.

Awais

Hi Awais,

I’m not familiar with that board or the RF examples.  For those questions I think it would be best to post a new thread the general MSP430 forum: http://e2e.ti.com/support/microcontrollers/msp43016-bit_ultra-low_power_mcus/f/166.aspx
