diags_USER1 is undefined

Other Parts Discussed in Thread: SYSBIOS

I'm migrating from DSP/BIOS to SYS/BIOS (CCSv5.2.2, BIOS 6.33.05.46, XDC Tools 3.23.03.53) and am seeing the following error:

Description Resource Path Location Type
#20 identifier "diags_USER1" is undefined main.cpp /Vibration Monitor line 826 C/C++ Problem

In my main.cpp, I have the following include files:

#include <xdc/runtime/System.h>
#include <xdc/runtime/Log.h>
#include <xdc/runtime/Diags.h>
#include <ti/sysbios/BIOS.h>
#include <xdc/cfg/global.h>

In my .cfg file I have the following defined:

var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Diags = xdc.useModule('xdc.runtime.Diags');
var Log = xdc.useModule('xdc.runtime.Log');
/* create trace logger */
var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');
var trace = LoggerBuf.create();

/* Set trace to be the default logger for the application. */
var Main = xdc.useModule('xdc.runtime.Main');
Main.common$.logger = trace;
/* Enable diagnostics for USER1 events for our program. Logging in the C
* Code will be done using USER1 events. Disabling this would disable all of
* the logging done in mailbox.c */
Main.common$.diags_USER1 = Diags.RUNTIME_ON;
BIOS.common$.diags_USER1 = Diags.RUNTIME_ON;

(NOTE: Although I posted a problem similar to this (Log_printx() in SYS/BIOS), this is not the same project. This is a brand new project but similar error.) Little help. Thanks.

Is this C/C++ code being complained about?

If so, I believe you need an upper-case 'D', e.g., Diags_USER1.

.cfg code uses 'diags_USER1' but in C-land it's 'Diags_USER1'.

Yes, this is C/C++ code. Changed 'diags_USER1' to 'Diags_USER1' and made sure I had both

#include <xdc/runtime/Log.h>

#include <xdc/runtime/Diags.h>

in any file that made reference to 'Diags_USER1' and the error went away. SPRAAS7G, Migrating a DSP/BISO 5 Application to SYS/BIOS 6 , (p. 43, Step 2, Step 4) makes reference to the following header files

#include <xdc/runtime/System.h>

#include <ti/sysbios/BIOS.h>

#include <xdc/cfg/global.h>

My project does not include these files (commented out) and I still don't get my original reported error:

Description Resource Path Location Type
#20 identifier "diags_USER1" is undefined main.cpp /Vibration Monitor line 826 C/C++ Problem

Thanks!

Yep, the general rule is that if you use an identifier (API function, data type, macro, etc.) from module "Mod" then you need to #include <modulepathname/Mod.h>

I'm not sure about global.h, but that document section is talking about the mailbox example specifically. The "general rule" I mentioned above applies here - if you use an identifier starting with "System_" then you should include its header file.

BIOS.h is probably included by some other header file that you *are* including. All SYS/BIOS applications need to at some point call BIOS_start(), which is declared in BIOS.h
