Cool! We can use netduino with another device more easily!

Hi Chris, I found "mchelper" is perfect alternative to SAM-BA! If we're using Mac OS X and having no Windows, no VM. mchelper is made to program MAKE CONTROLLER; But We can use this for netduino because its core is AT91SAM7X. But we must completely erase netduinos bootloader before program. We can download from this site, http://www.makingthi...rces/downloads/ Regards, Atsushi Saitoh

Hi all.
I'm in a trouble controlling a SDCard(1GB) with FAT16-formatted.
I changed the firmware of my netduino v.4.1.1-alpha usin MFDeploy.exe.
I use GPIO_PIN_D3 as CS-pin of SDCard.
Here's my code. And I could build with no errors.

using System;
using System.Threading;
using Microsoft.SPOT;
using System.IO;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.IO; 
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;

namespace NetduinoApplication3
{
    public class Program
    {
        public static void Main()
        {
            StorageDevice.MountSD("SD1", SPI_Devices.SPI1, Pins.GPIO_PIN_D3/*CS pin*/);

            string[] directories = System.IO.Directory.GetDirectories(@"\");
            Debug.Print("directory count: " + directories.Length.ToString());

            for (int i = 0; i < directories.Length; i++)
            {
                Debug.Print("directory: " + directories[i]);
            }

            string[] files = System.IO.Directory.GetFiles(@"\SD1");
            Debug.Print("file count: " + files.Length.ToString());

            for (int i = 0; i < files.Length; i++)
            {
                Debug.Print("filename: " + files[i]);
                FileStream fs = new FileStream(files[i], FileMode.Open, FileAccess.Read, FileShare.None, 512);
                StreamReader sr = new StreamReader(fs);
                Debug.Print("contents: " + sr.ReadToEnd());
            }
        }
    }
}

I connected my netduino with "TFT-LCD & SDCard shield"(this shield was made in JPN) hit "F5" key to start debug.
But VS2010 just say, "The debugging target is not an initialized state;rebooting".
So I Stopped debuging. And I plugged USB cable after unplugged my netduino,but There's no changes.VS2010 just say rebooting. :-p
So give me any advice?

Hi Szymon,

Thank you for your reply.
Yes, Japanese people came to be able to buy Netduino this week via SWITCHSCIENCE.(but netduino is sold out at once.)
A few people know the usage of .Net Micro Framework because they are using "FE* Domino".
Others are beginner of .NET Micro Framework.(Generally we (and Mr.Szymon!) are using C/C++ on embedded CPU )

Due to language barier it's hard for me to keep up with what you are doing. Hope you could give us some updates on cool project you are working on.

I also feel the LANGUAGE barrier. I'LL translate my job log until next Sunday in English.


Regards.
