hello to everybody

i would like to use timestamp to monitoring my application time.

in sopc builder i set timer 1 msec .

i follow documents and then i include the header file such as the documents

told me.

but when i compile to download exe file (.elf ) occur a console warning that

tell me is notpossible to find header file .

very strange .

somebody already use this function?

thanks for helps

ciao

#include "sys/alt_timestamp.h"# include "my_app.h"

alt_u32 time1;

alt_u32 time2;

int main(void)

{

if(alt_timestamp_start()<0)

{

printf("No timestamp device aviable\n");

}

else

{

time1=alt_timestamp();

}

while (1)

{

....................... //my application

........................//my application

time2=alt_timestamp();

printf("time execution= %u ticks\n",(unsigned int)(time2-time1));

}

}

"undefined reference to &#39; alt_timestamp_start &#39; undefined reference to

&#39; alt_timestamp&#39;

In effects these functions are not in the file "sys/alt_timestamp.h"

but i found them in the file "altera_avalon_timer_ts .c "

I try also to include this file but nothing

I cannot understand

could you be clearer?

Please explain to me exactly informations about your question slacker

thanks http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif

Do you have a "Timestamp timer" defined on the System Library properties page? If you do not, or don&#39;t know what I&#39;m referring to, please go look at this page (in the IDE).

The timestamp functions will not be compiled into your System Library unless you have one selected/defined.

these are the declarations related to the timer.

In sopc builder I have setted as from manual, but here in the file

result me "none".You can see at the end of file

# define SYSTEM_TIMER_NAME "/dev/system_timer"# define SYSTEM_TIMER_TYPE "altera_avalon_timer"# define SYSTEM_TIMER_BASE 0x00900800# define SYSTEM_TIMER_IRQ 1# define SYSTEM_TIMER_ALWAYS_RUN 0# define SYSTEM_TIMER_FIXED_PERIOD 1# define SYSTEM_TIMER_SNAPSHOT 1# define SYSTEM_TIMER_PERIOD 1# define SYSTEM_TIMER_PERIOD_UNITS "ms"# define SYSTEM_TIMER_RESET_OUTPUT 0# define SYSTEM_TIMER_TIMEOUT_PULSE_OUTPUT 0# define SYSTEM_TIMER_MULT 0.001# define SYSTEM_TIMER_FREQ 50000000

# define ALT_SYS_CLK SYSTEM_TIMER# define ALT_TIMESTAMP_CLK none# define ALT_MAX_FD 32

I follow instruction from manual .

It&#39;s possible make some change in this file , without regenerate in sopc

and compile in quartus II ?

If not , how i have to set flags in sopc builder ?

thanks for the answers

ciao

Walter,

I&#39;d advocate having two timers in your SOPC Builder system, one for the system clock timer and one timestamp timer.

The reason your design is failing is

#define ALT_TIMESTAMP_CLK none

Unless your SOPC Builder system has two timers, already, you&#39;ll have to add another one and re-generate/re-compile. You could also use the "system_timer" timer as your timestamp clock, but then you wouldn&#39;t have a system clock timer, and I don&#39;t advocate that!

Both the full_featured and standard "examples" have timestamp timers as well as system clock timers. You should change your SOPC Builder design so that it does too.

The key part, that you missed, is that you&#39;ve got to make sure your System Library properties are properly configured, prior to compiling your application. A quick browse through the Nios II IDE online help yields

Timestamp timer - Associates the timestamp driver to a timer device in the SOPC Builder system. The Timestamp timer and the Periodic system timer cannot specify the same physical device.

Unless you have a gigantic system, adding an additional timer to it shouldn&#39;t add more than a few seconds of generation/compilation time.

Best of luck,

yesterday i also add a new timer

Generate system and ricompile in quartus II

but in the system.h file i only read a new timer added , while the last lines at the end of file was the same

"none2 .

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

p.s. if i set "Writebke period " flag i loose full featured option

I have to not set this flag from the manual if i want to use

timestamp

It&#39;s very uncredible , every little thing became big in this system

To use timestamp is very easy from the manual , but what a have to do

is not possible to know

Yes... the default for Timestamp timer, in the System Library Properties page, is none. The build process, used by the IDE, will not (cannot, could not) automagically detect your new timer, you have to tell it to include the timestamp timer, by setting on the System Library properties page.

The timestamp timer does, by the way, work. You just have to understand how important the System Library properties page is to the build process.

Cheers,

yes i know

when i build a system in NIOS II IDE , the compiler take the system

.ptf , after quartus II compile , and after sopv builder generate.

So during building , IDE produce system. h , usiing address base specified in sopc

builder , and map all register of all component used .

Anyway , i posted the system.h above , and then i added a new timer

in cops builder , generate , update in quartus II and "start compilation " again .

After that in NIOS II IDE i build or rebuild all .

In the system.h file appear a new timer , but the last three lines about

timestamp remains the same .

At the end i cannot understand what to do , really ......

I saw all documentation files , but they only explain how to use timestamp

with some sample codes .

they explain that it&#39;s possible to use timer driver in two ways , like timestamp or

system timer and how to set the flags property page in sopc builder ...

...nothing else

Tomorrow i try to use my oscilloscope connected to the pc and set one output

port bit in the beginner and reset at the end of my program

And after try to understand the cycle time .
