Other Parts Discussed in Thread: SYSBIOS, MIDAS

I use the c64p time stamp provider to get cycle count. My cfg file has the following statements

var timeStamp = xdc.useModule('xdc.runtime.Timestamp');

timeStamp.SupportProxy = xdc.useModule('ti.sysbios.family.c64p.TimestampProvider');

In my code, I use staements like: Timestamp_get32();

I was previously using sysbios 6.31.5.31 and evrything was working.

I recently tried to switch to sysbios 6.32.5.53. I am now getting compilation failure with the following linker error

undefined first referenced

What could be the problem?

Murtaza,

Did you do a clean and a rebuild of your project? I don't see anything wrong the the TimestampProvider you are using since that's the default for both C64P and C66 devices.

Judah,

I am doing clean build. I can go back and forth between the two versions of sysbios and do clean build. It builds and works with version 6.31.5.31 but does not compile with version 6.32.5.54.

Murtaza,

Could you post your *.cfg file here?

Also, what profile are you building your project for? Are you building for "whole_program" or "whole_program_debug"?

Here is the full *.cfg file. I am using "release" build profile.

-----------------------------

var timeStamp = xdc.useModule('xdc.runtime.Timestamp');

// set to C64+ timestamp provider; c64x+ timestamp provider works for c66 as well

//timeStamp.SupportProxy = xdc.useModule('ti.sysbios.family.c64p.TimestampProvider');

Program.sectMap[".iobuff"] = "L2SRAM";

Program.heap = 0x2000;

Program.stack = 0x8000;

Murtaza,

At minimum you need to add the following to your .cfg file:

var BIOS = xdc.useModule('ti.sysbios.BIOS');

Also you need to do a xdc.useModule() for any Module that you are explicitly using in your app.
