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

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

[Ashish R Dhawane]

I am facing a problem in loading a binary file from minicom.
Whenver I try to load, it is going in an infinite loop.

=> 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.

-regards,
-Ashish

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

[ganapathi]

Hi Ashish,
    Check whether your serial_getc() function is returning 0. Your
serial_get() function should not return 0 if LSR_DR is 0.
I hope this will solve your problem.

Regards
Ganapathi C

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

[Daren Hayward]

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.

The DULG also warns you NOT to use minicom - for good reasons.

If you use kermit for file download anyway, just use it  as  terminal
program, too.

If you ask for my $ 0.02: minicom is broken. I recommend not to use it.

I know that others  like  it,  and  use  it  successfully,  so  chose
whatever you like, but don't say you have not been warned.

Don't use cu from minicom; use cu directly from the command line.

group uucp should have write permission on the  device,  and  in  the
lock directory.
