Excuse me for very long delay in response. Our target board is ML507 with PPC440 processor. Thanks very much.

Thank for your reply. Board can accept UDP packet. It can receive packet that generated with colasoft packet builder. Thanks again.

Hi all. I develop an application that send UDP packet to the embedded board. Embedded Board cannot receive packet because packet protocol changed to ARP. If I replace the Embedded Board with a PC and sniff network with WireShark, UDP packets are seen. what's the problem? If I send UDP packet with PacketBuilder to the Embedded board, it can receive it. I use MFC CSocket class to send UDP packet. My Code is:

CSocket sockSrvr;
if ( sockSrvr.Create(1239,SOCK\_DGRAM)==0)
{
	MessageBox("Can't create socket");
	return FALSE;
}
char	data\[100\];
memset(data,1,sizeof(data));
if ( sockSrvr.SendTo(data,sizeof(data),1239,"10.14.83.11")<=0)
{
	MessageBox("Error in Sending");
	return FALSE;
}
sockSrvr.Close();
return TRUE;

I test windows API to send UDP packet but not differ with CSocket. thanks for your help

Hi all friends I am developing an application on vxWorks and target board is ML507. My application receives data in loop from PC through a socket. If I set the "Default socket receive buffer size" to 48000, net speed is 210 mbps and worked normally. If I set it to 200000 in start the speed is very low and after a few seconds the network is hanged? Where is the problem? What is the best value for "Default socket receive buffer size"? :(( I searched the web but did not get the result. :(( Thanks for your help.

Greetings to all friends. I want to develop an application that decrypt an exe file format and save it in RAM and then run it . Developed application does not allow the save decryption output to a file. To run an exe application that is loaded to RAM I have no idea. Please guide me. Thanks to all friends

Hi everyone I'm developing an application in vxworks. In this application I use uart in polling mode for reading and writing. The problem is that when I disable uart interrupt using "intDisable" command, uart generally does not work in polling mode. The question is whether this is normal? Why uart does not work in polling mode if I disable it's interrupts. Thanks for the tips of your

Dear Richard Thank you for your quick answer, as I mentioned in the question and its title the problem is : "Low ethernet speed" Does you have any experience with VxWorks?

Hi all. In a design which is developed an application in VxWorks over ML507 evaluation board that receives some files through a ftp server via GB ethernet. OS of ftp server is Win XP. Problem is low speed of the network that is 110 MB/S. If evaluation board replaced with a PC that run client application on windows xp and get same files from same ftp server, speed is 700 MB/s. Please help me.

Hi all. I need to draw a thick line with SetPixel API. I search very, but can't find any open source algorithm (Bresenham algorithm is one pixel, murphy algorithm is for line with more than 3 pixel thick, ... ). If you can please help me. Notice that I can not use CPen and other facilities in windows. I should use SetPixel. Excuse me for bad English. Thanks.

Hello everyone, I want to read data from HID token in a PC(Personal Computer) bootloader.(For example in TrueCrypt bootloader). I search very very long in Google but couldn't find any solution about it. I am tired. :(( :( If you can, please help me. Thanks very much.

Hi all. I need to develop a program that manage a FAT or NTFS partition. It should directly access and analyze sectors in partition for its management, and it should can read files list, read file data,create new file and write data to that file. I search web very much but not found any open source app that match that I need. Is there any open source app that manage FAT or NTFS partition? If you can please help me. excuse me for bad English. Thanks a'lot.

Thanks a'lot for your attention and your nice response.

Hi. I want to develop in an embedded system. It's OS dos not support any graphic API and functions except SetPixel for developer. I need to use some standard font for text drawing. If you have any idea to do that, please share with me. Thanks very much.

Hi all. What is difference between "drive", "logical drive" and "partition" in disk organization? If a drive can contain some partition or a partition can contain some drive? What is difference between drive and logical drive? Excuse me for bad English and confused question. Thanks a'lot.

Hi. I need to create a new partition from free space of another partition or free space of a drive programmatically. how is it possible? Thanks a'lot.

Hi. Excuse me about my bad english. I develop First stage of a bootloader. Now I write it in first sector (sector number 0) of a hard disk. Then attach that hard disk to the system. When I turn on that system, it can't found my bootloader and run old bootloader that saved in hard disk. I search first 1,000,000 sectors of hard disk but old bootloader not found. What is location of old bootloader? If I Know it's location, I can write my bootloader in that location then BIOS can find my bootloader and run it. Thanks alot.

Hi friends. Excuse me for bad english. I developed a bootloader. I want to change interrupt 0x13 of BIOS in this bootloader. I can call old subroutine of 0x13 successfully but I don't know how change readed data.

void NewInterrupt13Handler()
{
__asm
{
leave
jmp cs:OldInt13Handler
}
Print("This line is not execute because of iret in old OldInt13Handler");
}
void Int13FilterEntry ()
{
__asm
{
leave
jmp NewInterrupt13Handler
}
Print("This line is not execute because of iret in old OldInt13Handler");
}

Hi all. How I can read & write from a HID device (like HID tokens) using it's port? I spent much time to communicate data with HID tokens in DOS program but ... ? :(( Thanks.
