how to run sys/bios example on C674x core of C6A8168?

Peng,

SYSBIOS has its *.cfg file.  This file along with the platform that you are building for generates a linker.cmd file for the project.
In general, you should not be adding another *.cmd to your project.  Its okay to add another *.cmd if necessary.

What are you using for print?  Is it System_printf()?  In some cases, you need System_flush to see the prints in the console window.

Regarding the output, you can look at it in Tools->ROV also. Look in the SysMin output tab.

Here is a discussion of SysMin vs SysStd (under the Configuring the System Module section): http://rtsc.eclipse.org/docs-tip/Overview_of_xdc.runtime/Example_1http://rtsc.eclipse.org/docs-tip/Overview_of_xdc.runtime/Example_1

The hello example is like this:

//////////////////

#include<xdc/std.h>

#include<xdc/runtime/System.h>

#include<ti/sysbios/BIOS.h>

void main(){

System_printf("hello world\n");

BIOS_exit(0);

}

////////////////

I build the sys/bios example,and load .out into  core C674x.
I think I should see "hello world" printed in the concole window. But there is nothing.

each time I click suspend button when program running, It seems the program pause at code" timer->tiocpCfg == obj->tiocpCfg | 0x2;" in Timer.c at line 186.

Could you tell me what's wrong with it?

thank you.

Can you look in ROV and see if there is SysMin. If there is, please read the "Configuring the System Module" section on the following web site: http://rtsc.eclipse.org/docs-tip/Overview_of_xdc.runtime/Example_1

Hi Todd,

I have tried your idea.But what troubles me is the program seems to stop at line 186 {function deviceConfig()} of Timer.c file.

So it is  never able to  run into main() function , let alone run the system_printf() function.

The line 186 of Timer.c file is " timer->tiocpCfg = obj->tiocpCfg | 0x2;// reset the timer".This file locates in /root/ti/bios_6_32_05_54/packages/ti/sysbios/timers/gptimer/ .

Are you loading the C674x core from CCS? Is it at line 186 or in the while loop, a couple lines below, waiting for the reset to finish?

Which timer is reseting (e.g. obj->id value)?

Todd

hi Todd,

I connect to C674x core as the page http://processors.wiki.ti.com/index.php/Connecting_to_DSP_on_C6A8168,_DM8168,_DM8148 says.

It is at line 186 . Because I kick out while loop below and it also halt at line 186.

I find     obj->id=0, obj->tiocpCfg=1

.

Can you attach your .cfg file?

When this happens, can you see anything the ROV->timers pages?

Now I can run a hello example of SYS/BIOS under simulation mode. I choose dsp core of C64x+ and platform of ti.platform sim64Pxx.

But when I choose C674x core and platform  ti.platform.simDM8168   I get the same error like in emulation mode as I posted above.It seems timers can't be initialized.

how can the SYS/BIOS example of  C6A8168 be simulated? Is it under developing or I make some mistakes?

francis

Hi Francis,

I'm going to try to replicate the example to see if I can reproduce the error.

Can you send the complete .cfg file, please?

hi,

The .cfg is in the .zip file.

I didn't make any changes to it.Do you mean I need to modify the .cfg to run the hello example in simulation mode?

thank you!

francis

Hi Francis,

I'm getting the same problem using the TI simulator (C67x CPU Cycle Accurate Simulator LE). Let me see what I can do to get the timer work with the simulator.

Hello everybody

I am getting same problem in simulator mode . But when i selected the ti.platforms.sim64Pxx platform , and then when i run the program it running in lines of Idle.c and Hwi_stack.c.

Here just i was testing, i need to run SYS/BIOS in C64x+ dsp of DM3730, i am getting the same problem ...what should i do ???

Should i use system flush()  instead of system printf().. Please help asap, because everything is fine except this error for project. I am doing some serious analysis problems.

With regards
