SYS.ABORTFXN with BIOS 6

BhavinKharadi

Hi,

Do we have any example code for the SYS.ABORTFXN and SYS.ERRORFXN functions? Customer is trying to use it but they are facing problem in doing that.

Hi Bhavin,

Could you please provide some more details on the problem the customer is having?

Also, which version of BIOS are they using?

Thanks,

Steve

Hi Steve,

Customer Normal 0 false false false EN-US X-NONE X-NONE

implemented the functionality as mentioned below.

// XX.cfg

var SYS = xdc.useModule('ti.bios.SYS');

SYS.ABORTFXN = "Lte_SysAbort";//_Lte_SysAbort;//"_Lte_SysAbort";

// XX.main

#include "assert.h"

void main()

{

start_bios();

}

Task_fxn()

{

assert(0);

}

void Lte_SysAbort()

{

int i;

while(1)

{

i++;

}

// But after exwcution of assert functionality, PC is not going to Lte_SysAbort().

Please let us know what is missing?

Steve,

One more thing. This is BIOS 6.

Hi,

I've created an example to demonstrate the usage of these features. I've verified that they are working. Please give the attached examples to the customer.

Thanks,

Steve,

Customer tried with the same file what u have provided. It works fine.

But he is not able to view the stack contents when the system is in the myAbort function (* he has put the breakpoint in myAbort func.)

Please let us know how to view the stack contents when system is going to abort or any exception handle.

Bhavin,

This is a bug. I have filed the following for it:

SDOCM00079857 Stack view does not show who called SYS_abort for user defined SYS.ABORTFXN in BIOS 6

Steve,

Is there any workaround for this bug? Is there anyway by adding some piece of code or something which can workaround this bug and allow us to view the stack?

Bhavin,

Yes, it seems that there's a possible work around. Can you have the customer try the following?

The customer needs to specify some compiler options for *all* C source files that they are building. This includes any generated files from the BIOS configuration:

add the following options when building _any_ source file that may be involved in the call chain (this includes the generated config .c file):

--symdebug:dwarf --optimize_with_debug

To add this option to the build of the generated config file you must add these options to the XDCtools "Build Properties" of your project:

Hello,

I would like to use the functionality invoked by SYS.ABORTFXN and SYS.ERRORFXN in DSP/BIOS 5 with an example usage with "xdc.runtime.System" in case of SYS/BIOS 6.

In short, SYS.ABORTFXN and SYS.ERRORFXN are present in DSP/BIOS 5 and "NOT" available in SYS/BIOS 6, so please suggest an example of such kind using "System" APIs in SYS/BIOS 6 application.

Thanks

Santosh
