µTasker general / cleaning up a socket with no connection

« on: April 17, 2014, 10:50:58 AM »

Hi Mark,
  What is the best way to clean up a socket if a connection isnt established?  I do the following steps:

  1. get a socket fnGetTCP_Socket(..)
  2. then call fnTCP_Connect(..) and set a 2 second timer using uTaskerMonoTimer(..)
  3. if a connection is established, then stop timer, if not then:
        a.  fnTCP_close() is called..
        b. TCP_EVENT_CLOSED within the callback is processed and fnReleaseTCP_Socket() is called.

Should the fnTCP_close() only be carried out if a connection is made, or simply call fnReleaseTCP_Socket()?

What I am noticing is the next time I am carrying out the above for fnGetTCP_Socket() ucTCP_state = TCP_STATE_ESTABLISHED for the previous fnGetTCP_Socket()


Best Regards
Neil

µTasker general / single tcp callback

« on: April 16, 2014, 06:41:06 PM »

Hi Mark,
  Is it possible to have a single tcp call back for multiple sockets (when using the fnGetTCP_Socket(..) command)? I have 10 sockets, but and would like to use just the 1 callback routine. Within the call back I go through the list of active sockets checking the socket number, so I can identify which one is being serviced.

   
Thanks
Neil

µTasker general / Re: Link Error

« on: November 25, 2013, 05:01:45 PM »

Hi Mark,
  Just noticed , the above is when I am NOT using the boot-loader.  The below is when I use the boot loader:

MEMORY
{
    flash   (RX)   : ORIGIN = 0x00001000, LENGTH = 0x0007F800
    vectorram(RWX) : ORIGIN = 0x20000000, LENGTH = 0x00000400
    sram    (RWX)  : ORIGIN = 0x20000400, LENGTH = 0x0000FC00   
    extram    (RWX): ORIGIN = 0x2040000, LENGTH = 0x00080000    /* {2} */
    ipsbar  (RWX)  : ORIGIN = 0x40000000, LENGTH = 0x0
}


When I am using boot-loader application, doesn't this use up to location 0x1000? When I program my app after the boot-loader, I start at memory address 0x1000. I thought the boot-loader is 0x1000 bytes long?

Regards
Neil

Hi Mark,
  I am using the 52259, and set everything up for 512k memory, but getting a segment overflow flash2 , see my linker file below. Looking at the linker file, below, I have changed the following and want to make sure there will be no issues:

changed:
    flash1  (RX)   : ORIGIN = 0x00000000, LENGTH = 0x001000

and
    flash2  (RX)   : ORIGIN = 0x00001020, LENGTH = 0x007EFDC

Many Thanks
Neil

utFAT / End Of File

« on: November 13, 2013, 05:09:14 PM »

Hi Mark
  I want to detect the eof condition after a read command (also before) do I simply check if the UTFILE.uFilePosition == UTFILE.uFileSize?  

  And if the both are the same, will a seek to the end place the file position at the same place, or 1 space after?

  I want to make sure if I read through a file until I get to the end (as above), and start writing, this is the same as doing a utSeek(&fd, 0, UTFAT_SEEK_END); , then start writing.

Thanks
Neil

Hi Mark
  I think it would be handy having an access(..) command similar to the windows version.

utFAT / checking for file existance

« on: November 08, 2013, 08:12:32 PM »

Hi Mark,
  Is there a command for checking if a file exists? I am using the open command, then closing if exists, but wondering if there is an easier way.

Thanks

Hi Svl,
 Thanks very much for that. Will this work on Intel and AMD chipset ? And only require the inf file? 

I havent got Windows 8 yet, but I will post the inf for it, if I get a hold of it.

Thanks

µTasker general / valid tcp packet communication

« on: June 19, 2012, 06:08:04 PM »

Hi
  When a standard tcp connect is established with a server, am I right in thinking that the sending side includes a checksum of the packet? Then the server will only pass the packet to the user if the checksum is valid, is this correct?

Also, if the above is correct, then I assume there is no need to add my own checksum calculcations?

Thanks

Hi Mark,
  Thanks for taking a look at the card. I am wondering if this is a faulty batch, as another one of the 2GB cards displays 255MB when formatted in Windows FAT 32.

Thanks
