C# in embedded systems

2007-10-05T03:37:00.000-07:00

Most of the times developers uses C language to write embedded applications. If time is not an issue or its not critical you can easily use java or c#
Microsoft has now 3 platforms for embedded:

Windows XP embedded for large systems
Windows CE for small to medium systems
.NET micro framework for very small devices

to use C# and .NET you can use:

.NET framework in XP embedded
.NET compact framework for windows CE
.NET micro framework - native

.NET micro framework supported by some small devices such as this board

useful mounting options

2007-10-05T02:41:00.000-07:00

In Embedded linux development process it is very common to create a mount points from target to host and between hosts. some useful commands

mounting NFS file system:

the nfs server name is NFSSERVER and its IP address is: 192.168.20.34
the server directory is /opt/files and it is configured with permissions on the server (/etc/exports file). also the client added the server IP and name to its /etc/hosts file.

# mkdir /mnt/nfsserver
# mount -t nfs NFSSERVER:/opt/files /mnt/nfsserver

if you cant configure the server name on /etc/hosts file you should use the IP address:

#mount -t nfs 192.168.20.34:/opt/files /mnt/nfsserver

mounting Windows system

the windows workstation is WINWS with ip: 192.168.20.70
make sure SAMBA daemon(service) is running on your linux system - depends on your distribution.

# mkdir /mnt/windows
# mount -t smbfs -o username=winuser,password=pass //192.168.20.70/linux_files /mnt/windows

NOTES:

If you get an error try cifs instead of smbfs
sometimes (IT reasons) it is working only with the server name (not IP address) and sometimes only with IP so try both if you have problems

Loop mount image file

# mount -o loop file.img /mnt/image

mount USB disk on key

# mount /dev/sda1 /mnt/usb

for more options and situations see man pages

Makefiles for loadable module development

2007-10-05T02:09:00.000-07:00

In linux module development you should use the kernel Makefile to compile your source. You have to write a tiny Makefile to do it. Many times the module built from only one source file, but not always. To build a module download the kernel source and use the same toolchain you used in the kernel build process.

The makefile for one source code - simple.c
-------------------------------------------
CC=gcc

.PHONY: modules all

obj-m := simple.o
KERNELDIR := /path/to/linux/kernel/source
PWD := $(shell pwd)

all: modules

module:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

clean:
rm *.ko *.o
--------------------------------------------

Makefile for many source files module
--------------------------------------
CC=gcc

.PHONY: modules all

obj-m := multi.o
multi-objs := file1.o file2.o file3.o
KERNELDIR := /path/to/linux/kernel/source
PWD := $(shell pwd)

all: modules

module:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

clean:
rm *.ko *.o

Embedded Linux - Loading The Kernel

2007-09-29T14:31:00.000-07:00

Now we are ready to operate the board
we want to load the kernel inside the board flash memory and mount the file system in out host computer. this is very useful in the development process because the only thing we should do to download out application/driver to the target is to copy it from one directory to another on the host computer

restart the device and press a key to get u-boot shell
the easiest way to load files from host to target is to use tftp server on the host.
start the tftp server and place the kernel image (uImage.cc) in the server directory

on the target uboot shell:

# setenv serverip [your tftp server ip address]
# tftpboot 0x10000000 uImage.cc
after this you will get a number in hex format - REMEMBER IT

now we should erase the flash memory : (bank 8 to 20)

# erase 1:8-20
# cp.b 0x10000000 0x100000 [the number above]

now set the bootargs variable:

# setenv bootargs console=ttyS0,115200n8 noinitrd ip=${OSK_IP}:
${PC_IP}:${GATEWAY_IP}:${NETMASK}:osk:eth0:off root=
/dev/nfs rw nfsroot=${PC_IP}:/data/rootfs2.6,nolock mem=32M
# saveenv

to test the board restart it or:

# bootm 0x100000

after all the messages , you will get a prompt with the file system on the host

now you can use the toolchain to build applications and drivers, copy the output files to the root filesystem directory and execute/load it from the target

Embedded Linux - Root File System

2007-09-29T14:19:00.000-07:00

The next step in to build a root file system.
there are many ways to do that. we are using busybox
busybox creates a single file that implements many tools from the file system
you can download it and configure it using "make menuconfig"
the only thing you should remember is to copy the .so files from the lib directory in your toolchain (usr/local/arm/3.4.1/arm-linux/lib) to the lib directory in the root file system

for already made file system click here

after creating the file system place it in a directory and update the file /etc/exports with access rights :

/opt/osk/rootfs2.6 *(rw,no_root_squash)

restart the nfs server

Embedded Linux - building the kernel

2007-09-28T03:14:00.000-07:00

The next step is to build the kernel with our toolchain
you should download the kernel source and a patch

download kernel 2.6.20 (from http://www.kernel.org/)
download the board kernel patch

now follow this:

# tar -xjvf ${DOWLOADDIR}/linux-${VERSION}.tar.bz2
# cp ${DOWLOADDIR}/patch-${VERSION}-omap1.bz2 .
# bunzip2 patch-${VERSION}-omap1.bz2
# cd linux-${VERSION}/
# cat ../patch-${VERSION}-omap1 | patch -p1

# make clean
# make omap_osk_5912_defconfig

make sure that the following options are set:
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_ROOT_NFS=y

# make

now the kernel image is ready but we have to convert it to U-BOOT format

# arm-linux-objcopy -O binary -R .note -R .comment S
arch/arm/boot/compressed/vmlinux linux.bin
# gzip -9 linux.bin
# ${U-BOOTDIR}/tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10c08000 -e 0x10c08000 -n Linux Kernel Image -d linux.bin.gz uImage.cc

uImage.cc is ready

Embedded Linux - boot loader

2007-09-28T02:11:00.000-07:00

The next step in our osk system is to build and set the boot loader
the OSK board comes with already installed U-BOOT,
we can replace it but we don't need
we do need a tool: mkimage to convert the kernel image to U_BOOT format
to build the tool download U-BOOT source

do the following:

# tar -xjvf ${DOWLOADDIR}/u-boot-1.1.2.tar.bz2
# cd u-boot-1.1.2
# make distclean
# make omap5912osk_config
# make tools

you can also run make to create the binary image of u-boot boot loader so you can replace it on the board but we don't need it (future post)

if you look inside the tools directory you will find the tool mkimage

Embedded Linux - Toolchain

2007-09-26T04:39:00.001-07:00

The next step for our OSK system is to find or create a toolchain
we need a toolchain for ARM processor

Building a new toolchain can be complicated mission
in general you should download:

binutils - http://ftp.gnu.org/gnu/binutils/
gcc - http://ftp.gnu.org/gnu/gcc/
C library - http://ftp.gnu.org/gnu/glibc/
some extensions

then configure and build a binary image of your toolschain (future post)
for our purpose we can use an already made toolchain from here

extract the archive:

# tar -xjvf ${DOWLOADDIR}/arm-linux-gcc-3.4.1.tar.bz2

look at the path: ${EXTRACTEDDIR}/usr/local/arm/3.4.1/bin
(all the binary tools to compile, link and debug an ARM code)

add the above path to your PATH environment variable :

# export PATH=/usr/local/arm/3.4.1/bin/:$PATH

now we can build everything with this toolchain

Timers problem on Windows 2003 server

2007-09-17T01:47:00.001-07:00

In a SOA solution sometimes we need to set a timer on a web service to manage some tasks.
for example if we have cached data and want to flush it to a database each 30 seconds we can create a timer for this task
the problem is that the timer runs on anonimous identity and cant access the database
the problem exist only on Windows 2003 server, on XP pro it runs with ASPNET user identity
to solve it, create a thread that do that job and sleep for a 30 seconds
Another problem with the thread - it access database or other resource with network service identity and its a very weak account - so if the resource is located on other computer change the application pool identity to other domain user

Marshaling structures over TCP/IP

2007-09-17T01:47:00.000-07:00

[this post came from our old blog]
To create a distributed application you can use TCP/IP, Remoting, Web Services, WSE etc.
There are 2 benefits with TCP/IP:
Performance Connecting .net application to legacy applicationsWhen you use for example a TCP server written in C on of the problems is to marshal structures.
.NET socket class provides a Receive method that fills a byte buffer.
The only problem is to convert it to the structure

Some ways I know:

Option 1: Using MemoryStream and BinaryReader (field by field)
C struct:
struct Demo{
int x;
int y;
};

C#
class Demo
{
public int x;
public int y;
}

Socket s = tcpl.AcceptSocket();
byte[] buf = new byte [100];

int bytesReceived = s.Receive(buf);
Demo d = new Demo();
MemoryStream m = new MemoryStream(buf);
BinaryReader br = new BinaryReader(m);
d.x = br.ReadInt32();
d.y = br.ReadInt32();

Option 2: using unsafe code (field by field)
You have to compile with /unsafe option and your code is not secured but its faster

unsafe
{
fixed (byte * p1 = buf)
{
int* p = (int *)p1;
d.x = *p;
d.y = *(p + 1);
}
}

Option 3: using Marshal class (all at once)
Its easy because you Marshal the structure at one time but its very inefficient (marshaling to the unmanaged heap and back to the managed heap)

[StructLayout(LayoutKind.Sequential)]
class Demo
{
public int x;
public int y;
}
......

Socket s = tcpl.AcceptSocket();
byte[] buf = new byte [100];

int bytesReceived = s.Receive(buf);
Demo d = new Demo();
IntPtr p1 = Marshal.AllocCoTaskMem( Marshal.SizeOf(typeof(Demo)));
Marshal.Copy(buf, 0, p1, Marshal.SizeOf(typeof(Demo)));
Marshal.PtrToStructure(p1, d);
Marshal.FreeCoTaskMem(p1);

option 4: using struct

if you declare it as struct (with all its constrains)
unsafe {
fixed (byte* p1 = buf) {
Demo* p = (Demo *)p1;
d = *p;
}
}

Starting a service and WMI

2007-09-17T01:46:00.000-07:00

[this post came from our old blog]
One of my students asked me how to start/stop a service from .net application. The simple way to do it is using the ServiceController class:

ServiceController sc = new ServiceController();
sc.ServiceName = "Dnscache";
sc.Stop();

Another way is to use WMI
2 ways to do it:
A. Using classes from System.Management namespace
B. Generate .NET proxy class to access WMI class:

Example(B)

1. Using visual studio command prompt type :

C:\demo>mgmtclassgen win32_Service

Microsoft (R) .NET Framework Version 2.0.50727.42
Copyright (C) Microsoft Corporation. All rights reserved.
Generating Code for WMI Class win32_Service ...
Code Generated Successfully!!!!

2. Add the generated file to your project
3. Add reference to system.management.dll
4. Use the class

Service s = new Service(new ManagementPath("\\\\localhost\\root\\cimv2:Win32_Service.Name='Dnscache'"));

s.StartService();
//…….
s.StopService();

WMI helps in many management tasks like installing software, monitoring events etc.
Note that within windows 2003 Server Microsoft added many methods to WMI classes. Using the above tool in windows 2003 server usually generate a bigger class file

Out of resource - TCP ports

2007-09-17T01:45:00.000-07:00

In A SOA solution we want to create a client that loads the server with many requests
we wrote too clients :

java client - runs on linux with AXIS toolkit
c# client - runs on windows using .net FCL and WSE 3.0

both clients crashed after a while with the error : "too many open files" of "out of resources"
the problem is the use of many TCP ports without release (that managed automatically by OS)
The OS allow you to use limited number of port concurrently and free the unused ports once in a while - if you want more ports in the interval it will fail

2 solutions

Set HTTP keep-alive both on client and server that means that you use the same port for each request (this can be problem if using built in load balancing feature)
Raise the port number limit

To raise the port number:

On Windows Registry: set the following
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TCPTimedWaitDelay"=dword:0000001e
"MaxUserPort"=dword:0000fffe

On Linux:
open the file etc/security/limits.conf and set nofiles=N

Embedded Linux - Connecting to the device

2007-09-11T00:09:00.000-07:00

The device (osk5912) comes with a system based on kernel 2.4
the next step is to connect it using RS232 (null modem cable) to your host machine
to see the device terminal you can use windows or linux

On Windows Host
use hyperterminal : set the connection to the correct COM port with the following settings: 115200 baud, no parity, 8 data bits, 1 stop bit , no flow control
connect the device to power and push the reset button on it (small white button)

On Linux Host
first setup minicom

# minicom -s

select serial port setup
set the following:

Serial device - /dev/ttyS0 (or other number based on your com port)
Bps/pas/Bits - 115200 8N1
No software flow
No hardware flow

save setting and Exit (to minicom)

(the setup step is required only once so next time just run minicom)

push the reset button on the board

You can now play with the system and with some demos provided from MontaVista

We dont want to use kernel 2.4 and also want to build our system with free software so we will not use Montavista distribution

Note: The porpose of this posts is to study embedded linux and thats why we dont use the commercial distribution. there is no real free software, if you use Montavista or other commercial distribution you pay (around 15000$ for developer) but you get full support and much work have been done for you (BSP,device drivers and sample programs). when you use the "free" tools you have to spend time to solve problems and creating the BSP and you know - "time is money"

Embedded Linux - Setting up host

2007-09-10T15:34:00.000-07:00

the first thing to do is setting your host machine
Install one of the Linux desktop distributions on your host
make sure that it includes:

C/C++ development tools
NFS server

I'm using Open SUSE 10 on one workstation and fedora code 3 on another

Embedded Linux - Starter Kit

2007-09-10T15:21:00.000-07:00

To deal with a real system you should buy the OSK 5912 Board
to buy it go to: this site

the board is based on ARM processor with DSP Processor and you can evaluate also Montavista distribution (kernel 2.4)

we will use it to with only free software tools includes:

Toolchain
Boot loader
Kernel
Root file system
