propeller-load save to SD card

AS · 2016-02-13 16:15

Hello!

Is everything working fine, I install a SD card and I can do all the examples.
I want saving to the SD card because I have a large program.
I´m working with a Raspberry, I tested in two models.
I´m using CMake to creat the ".elf" files.

With the memory model "lmm" everything is working, I see the Hello World!
I wrote:

make debug

or

/opt/parallax/bin/propeller-load -b activityboard GettingStarted.elf -r -t

with the file CMakeLists.txt:

cmake_minimum_required(VERSION 3.3)
find_package(PropWare REQUIRED)

project(GettingStarted)

set(MODEL lmm)
set_compile_flags()

create_simple_executable(${PROJECT_NAME} GettingStarted.cpp)

Now I change the memory model to

...
set(MODEL xmmc)
...

After:

cmake ..
make

I can´t do the

make debug

but I can use:

/opt/parallax/bin/propeller-load -b activityboard -l GettingStarted.elf -r -t

Everything seems fine! No warnings No errors! BUT NO HELLO WORLD!?

And I have in the SD card the file AUTORUN.PEX

Hmm... interesting. I'll start looking into this. I also recently picked up an Activity Board so I should be able to replicate your issue exactly.

DavidZemon · 2016-02-13 19:43

Oh, just FYI, you can remove the "set_compile_flags()" line. That was only needed in conjunction with "add_library()"

David Betz · 2016-02-13 20:49

Can you please post the .elf file you're trying to load?

I take a foto with my propeller kit with the SD, I just choose the activityboard because I think that is the same!

The file activityboard.cfg I don´t had change nothing:

# Propeller activity board configuration.
# IDE:SDXMMC
    clkfreq: 80000000
    clkmode: XTAL1+PLL16X
    baudrate: 115200
    rxpin: 31
    txpin: 30
    cache-driver: eeprom_cache.dat
    cache-size: 8K
    cache-param1: 0
    cache-param2: 0
    eeprom-first: TRUE
    sd-driver: sd_driver.dat
    sdspi-do: 22
    sdspi-clk: 23
    sdspi-di: 24
    sdspi-cs: 25

About the "set_compile_flags()", Thanks!! (only for libraries :thumb: )
I already try without them and I get the same result.
I hope you can give any help.

I send the file attached, I save it inside the rar because the forum don´t accept the .elf file.

Can you post it as a .zip or .tar file? I don't have an application that can open a .rar file.

AS · 2016-02-13 23:23

I attached the .zip file.

AS · 2016-02-14 00:50

I was thinking about the "activityboard.cfg", I have only a EEPROM of 32kb and activity board have 64kb. I need change this file?

Yes, it does. You must have at least a 64k EEPROM to use the EEPROM cache driver. It won't work with a 32k EEPROM.

Thanks for posting this. Can you tell me what version of PropGCC you're using? Is it the old one that comes with SimpleIDE or a newer build?

David Betz · 2016-02-14 01:10

I've been reading over this thread and I'm not sure what you're trying to do. Do you want to run a large program directly from the SD card or do you want to run it from EEPROM? You don't need a 64k EEPROM to use the SD cache driver. you only need it for the EEPROM cache driver.

AS · 2016-02-14 02:01

I´m using the PropGCC version that comes with SimpleIDE for Raspberry.

OK! sorry!
I want use a large program directly from the SD card. In this case is not important the EEPROM if it is 32 or 64kb?
I read something about the driver to open the "autorun.pex" and I thought that the size of EEPROM could be important!

Thanks!

Thanks. I'm building release_1_0 so I can test this. I've mostly been working on a much more recent version of propgcc lately.

David Betz · 2016-02-14 14:30

I'm not sure what's going wrong with this program. I tried just loading and running it and it doesn't seem to print anything. I did this on a real ActivityBoard with a 64k EEPROM. What is it supposed to do?

The program is a simple "Hello World":

#include <PropWare/printer/printer.h>

/**
 * @example     GettingStarted.cpp
 *
 * Print some text to the terminal. A great place to start with PropWare to ensure your environment is functional!
 *

    pwOut << "Hello, world!";
    return 0;

The same program with memory model "lmm" is working great.

in this case I type:

/opt/parallax/bin/propeller-load -b activityboard GettingStarted.elf -r -t

and it works!

I attached a .zip (of a .elf file) with the same program compiled in lmm mode.

AS · 2016-02-14 17:23

The 1st .elf I sent was built with "xmmc" memory model.
To save the "AUTORUN.PEX" to the SD card I should write:

/opt/parallax/bin/propeller-load -b activityboard -l GettingStarted.elf -r -t

It´s necessary the "-l"? Right? To save the program to the SD card in the mode "xmmc"?

and I obtain the result:

At this moment I already have the "AUTORUN.PEX" file in the SD card.

I write:

/opt/parallax/bin/propeller-load -b activityboard -l -r -t

and the result is similar, no "Hello World":

Something odd is going on. I tried your program on a C3 board it didn't work there either. Then I tried this program:

#include <stdio.h>

int main(void)
{
    printf("Hello, world!\n");
    for (;;)
        ;
    return 0;
}

And it works fine with both the EEPROM cache driver and the C3 cache driver.

Hello, world!

Could it be that you need a delay at the end to see the output? I'm not sure why that would be required in XMMC mode but not LMM mode though.

AS · 2016-02-14 19:42

With LMM mode everything is working ok with me too, I see the "Hello World".

The issue is when I compile in XMMC mode and try to upload to Propeller, using the SD Loader (-l) or SD CacheDriver (-z).
I already made several tests and the Propeller don´t run the program. I try the delay too, but nothing.

Can you try the simple program I posted a few messages ago and let me know if that works for you?

Here is the output I get when I use -z on a real ActivityBoard with the version of PropGCC that comes with SimpleIDE:

ok! with the code you send me it works!!!

Really thanks!

but I can´t understand why

I should write in the code something like:

...
    for (;;)
        ;
    return 0;
}

with a "while(1)" I should write it in every cycle?
Ok I will test it!
thanks!

David Betz · 2016-02-14 21:39

The problem is that when main() exits it shuts down the COG and prevents any buffered output from being sent over the serial interface.

AS · 2016-02-14 21:50

Thanks a lot!

Is not easy to me really understand.
But I will test it.

To be honest, I don't understand why this happens with the XMMC memory model but not with LMM either.

AS · 2016-02-14 22:17

Exactly.

I trying to understand how is the best way to deal with that.

David Betz · 2016-02-14 22:25

Is this really a problem? Any real program will probably not just print a line of text and immediately exit. Normally, a program sits in a loop monitoring events and reacting to them. In fact, most microcontroller programs never exit from main() at all. The empty loop I put at the end of my example simulates the event handling loop that would normally be in any Propeller program.

AS · 2016-02-14 23:12

ok!

But with this example I have the same issue:

#include "simpletools.h"                                       

int main(void)                                   
{

  int Led_Intensity=0;
  pwm_start (1000);

  while(1)                                    // Endless loop
  {
    
    while (Led_Intensity<1000)
    {
      pwm_set (0,1,Led_Intensity);
      Led_Intensity ++;
      pause (1);
    }  
    
          
    while (Led_Intensity>0)
    {
      pwm_set (0,1, Led_Intensity);
      Led_Intensity --;
      pause (1);
    } 
     

  }

}

the led don´t react in XMMC mode.
with LMM everything ok, with XMMC don´t work.

Well, this is certainly a different problem as you suggest. I'm afraid I'm not familiar with the PWM functions. I'll let someone else who is more familiar with the Simple Libraries answer this one.
