[U-Boot-Users] Loadb issue

[U-Boot-Users] Loadb issue

[Banajit Goswami]

Hi All,
 I am a new member to this mailing list.

 I am porting u-boot to a arm926ej board. I have a serial port which I am
trying to use to download a binary image. But I am not able to do so. I am
trying to use loadb and loads and both seems to be failing.

Here is a typical sequence i followed
  1) Boot-up the board
  2) Connected to Hyperterminal (tried minicom, cu, kermit and dnw) with 8N1
and hw-flw control as "none".
  3) at u-boot command prompt gave following command
         => loadb 0x60008000 115200
  4) From hyperterminal, Transfer->send file with protocol as kermit,
selected the file and tried sending, but failed. Everytime  hyperterminal
poped up "error limit exceeded".

# loadb
## Ready for binary (kermit) download to 0x60008000 at 115200 bps..

 When tried looking the point where it is geting stuck, I saw u-boot waiting
in the while loop looking for the 'START_CHAR' in the following section of
code:

k_recv(){
.....
....
  for (;;) {
      switch (getc ()) {
        case START_CHAR: /* start packet */
             goto START;
        case ETX_CHAR:  /* ^C waiting for packet */
             return (0);
       default:
             ;
      }
  }
....
...
}

 I am not sure how to use 'loadb' and 'loads'. Read a few docs about uses
though, none explained what needs to be done in implementation part.

 Can anyone give me some pointer, as in, any board which has implemeted and
using any of the commands? What might have gone wrong here??

Or any other commands I can use for serial download of binary image?

Thanks in advance
Banajit

Are you sure that you are using the same baudrate for terminal mode
and kermit mode? Do the RS232 level converters have their own supply
or do they get it from the modem control lines? Although you selected
no handshake this doesn't neccessarily mean that the control lines
don't get toggled.

With best regards

Hi Banjit,
                How much memory (RAM)  you have?  Also check the PINSEL and BCFG configurations along  with the baud rate setting in u-boot code.
                 Those commands are working fine for my hardware which is arm7TDMI board.
  
  Thanks and Regards,
  Kaushik

[U-Boot-Users] Loadb issue

[Banajit Goswami]

Hi Andreas/All,

 Thanks for the reply.

 I am using same baudrate for terminal as well as kermit modes. both are
with 115200.

 I am getting the prompt on console over serial and able to execute commands
like help, bdinfo, md and mw etc.

 I am sending a log herewith with some of the commands' execution as well as
the .kermrc file that I am using.

Any pointer would be of very much help.

Thanks and Regards
Banajit

This cannot work. The "loadb" command expects that you  transfer  the
data  using  kermit  binary  protocol, not just dumping some raw data
over the line.

Kermit *binary* protocol means that you should send in *binary* mode,
so have to use the "/bin" option.

All this is written in good detail in the manual, so please RTFM!!!

Thanks for the pointer. Will maintain it in future.


And STOP sending HTML!!!!


I have no idea why it is sent as HTML. I am using my gmail account.

I am using the command "set file type bin" in the .kermrc file. The file is
similar to what is mentioned in the website
http://www.denx.de/wiki/view/DULG/SystemSetup#Section_4.3.

All this is written in good detail in the manual, so please RTFM!!!
> See http://www.denx.de/wiki/view/DULG/UBootCmdGroupDownload


I am following the same procedure as mentioned.


Thanks and Regards

Nobody cares WHY you are sending as HTML! DO NOT SEND HTML to this

Please get a clue how to configure your mailer before posting again.

Similar may be not good enough.
