RE: [U-Boot-Users] U-Boot/Kermit Problem

29 Apr 2004


      I had a similar problem I ended up getting it to work with using the 
following
SET PREFIXING ALL
SET PARITY NONE
SET CARRIER-WATCH OFF
also ensure there is no handshaking see the kermit manual for more 
information.
I have placed the above commands in ~/.kermrc so they are picked up by 
minicom when it calls kermit.
btw they recommend not using minicom for serial transfers, I have used 
U-boot v 1.1.1 with minicom serial file transfer with no problems though.

Subject: [U-Boot-Users] U-Boot/Kermit Problem
Date: Thu, 29 Apr 2004 11:58:28 +0500 (GMT+0500)
I am facing a problem in loading a binary file from minicom.
Whenver I try to load, it is going in an infinite loop.
=&gt; loadb 100000
## Ready for binary (kermit) download to 0x00100000 at 9600 bps...
I configured kermit as told in the DULG/SystemSetup Manual....
Only change I made is
set speed 9600 instead of 115200
I am getting stuck here. After going through the u-boot source code ....
The calling sequence is ....
-load_serial_bin
-k_recv
Inside k_recv the code where I stucked up here is ...
----------------------------ACTUAL CODE-----------------------------------
                 /* get a packet */
                 /* wait for the starting character or ^C */
                 for (;;) {
                         switch (serial_getc ()) {
                         case START_CHAR:   /* start packet */
                                 goto START;
                         case ETX_CHAR:  /* ^C waiting for packet*/
                                 return (0);
                         default:
                                 ;
                         }
                 }
----------------------------ACTUAL CODE UP TO HERE------------------------
I think it continiously in the for loop.
When I press control-C then it will come comeout saying ....
## Total Size      = 0x00000000 = 0 Bytes
## Start Addr      = 0x00100000
Can anyabody help me why it is happening ?
Any help will be appreciated.
