Some more information.

For a variety of reasons I've had to do a few build on a slow system. One bit that seemed

exceptionally slow is the 'binToAsm' call (just after the 'deflate' generating vxWorks.Z.s).

This is done by

od -bv $infile |

sed -e "s/^[0-9]*[ ]*//;

s/ /, 0/g;

/^[0-9a-fA-F][0-9a-fA-F]/s/^/ .byte 0/"

(ie use od to generate a list of octal bytes, remove the offset, change the spaces to comma,

add the directive - an extra 0 is added to each number to ensure they are octal).

The above is terribly slow... Slightly faster (under solaris) is:

od -An -v -tu1 $infile | tr ' ' ',' |

sed -e 's/,00*\([0-9]\)/,\1/g;s/^,/ .byte /'

However it is clear that a C program would be even faster... It was still sluggish using

printf, so...

2.2.3 SHELL

A: shell

d()l()

magic code

The shell is an unbreakable task, so all the time it is running the breakpoints are not

installed. When a context switch causes a breakable task to run, the breakpoints will be

resinstated.

So, to see the breakpoint in memory simply spawn the d() command or l() command. That will

then run in a breakable task, and you should see the magic code inserted to cause

an exception.

2.6.4 C

A: makefile

%.out: %.o

@objdump$(TOOLENV) -S $< < $@

This will generate a file called .out containing C and assembly code. You need to have

the -g flag for the compiler to get debug informtion in the output file. This information is

needed by objdump.

But this is probably not enough. By default VxWorks puts a name in the object file. This name

consists of the absolute path of the project directory with the complete path of the file name

appended to it. (This can be seen with the command "objdump$(TOOLENV) --debugging

", in the first few lines the filename is given.) This is caused by the fact that

the compiler is called with the complete path of the sourcefile. This can be changed to ".." in

the Makefile. But the Makefile is generated each time the configuration is changed.

To correct this the file prj_vxApp.tcl can be changed to write ".." to the Makefile istead of

the complete path. This is done in the function makeGen. The original line in this function is:

puts $fd "PRJ_DIR = [file dir [prjInfoGet $hProj fileName]]"

This should be changed to:

puts $fd "PRJ_DIR = .."

7.10.2 tornado 2 :

Linking the application with VxWorks is really a two-step process. You must add an entry point

to the application in usrConfig.c, and you must modify the makefile to link the application

statically with VxWorks.

To start your application during system initialization, add code to the usrRoot( ) routine in

usrConfig.c. You can call application initialization routines, create additional I/O devices,

spawn application tasks, and so on, just as you do from the Tornado shell during development.

An example is provided in usrConfig.c. This file includes and initializes a simple demo if the

preprocessor constant INCLUDE_DEMO is defined in one of the configuration files. In that

situation, usrRoot( ) spawns usrDemo( ) as a task as the last step in booting the system. You

can simply insert the appropriate initialization of your application after the conditional

code to start the demo. For example:

/* spawn demo if selected */

#if defined(INCLUDE_DEMO)

taskSpawn ("demo", 20, 0, 2000, (FUNCPTR)usrDemo, 0,0,0,0,0,0,0,0,0,0);

#endif

taskSpawn ("myMod", 100, 0, 20000, (FUNCPTR)myModEntryPt,

0,0,0,0,0,0,0,0,0,0);

To include your application modules in the bootable system image, add the names of the

application object modules (with the .o suffix) to MACH_EXTRA in Makefile. For example, to

link the module myMod.o, add a line like the following:

MACH_EXTRA = myMod.o

...

Building the system image with the application linked in is the final part of this step. In

the target directory, execute the following command:

make vxWorks

tornado 2rebuild AllvxWorks,bootrom.sys

vxWorks;vxWorks
