[U-Boot-Users] Remote Kermit Not Responding

[Rodel Miguel]

Hi,

I need help on downloading binary image from host to the board where I
am porting U-Boot.  My host is Windoze XP and I downloaded the
freeware version of kermit terminal emulation tool.  I can now execute
some commands successfully, e.g. go, printenv, help, etc.  However,
when I try to download a binary image using kermit's send, and typing
loadb to the serial console, the message "Remote Kermit Not
Responding" is logged on the terminal.  When I type ^C, the message
states that I have downloaded 0 bytes.  What could be causing this
problem?  What U-Boot configuration might I have missed out?  What
part of the U-boot code should I be looking at if my configuration is
correct?

Thank you very much and best regards,

Rodel Miguel

This sounds as if you were trying to do it in the  wrong  order.  You
are  aware  that  you  FIRST start "loadb", then disconnent, and only
then type "send /bin ...filename..." at the kermit pro,mpt?

This is most likely a usage error. See the  manual  for  instructions
how to configure Kermit.

Hi,

I am using windoze kermit.  So, I would type loadb first.  Then, click
on kermit->send.
Am I doing something wrong here?  Are there options needed by u-boot
to successfully communicate/download files with kermit, i.e. protocol?

Thanks,
Rodel

P.S. Doesnt the fact that I could type commands successfully means my
UART is working and downloading binaries on the same UART port using
loadb would be just as easy as clicking the send option in kermit?

Did you read what I replied to  you  first  question?  I  don't  like
repeating myself.

In other words: are you sure you're using kermit BINARY protocol  for
sending?

Did  you  read  the  manual  about  the   necessary   /   recommended
configuration settings?

[Maybe you want to dump windoze kermit for a moment (who  knows  what
that  might  actually  be doing) and use the real kermit under Linux;
once you got this running you can try and go back  to  windoze  fight
the problems of this hostile environment.]

Hi Wolfgang,

Thanks for your time.  I followed the manual line by line. :) but I
didnt get through the loadb command.  I am using the kermit of Suse
9.1.  Did some changes on the .kermrc to support my board whose max
uart baudrate is 19200.  I used the ff:

set line /dev/ttyS0
set speed 19200
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set  rec pack 1000  (also tried lower values for rec and send without
success, 167)
set send pack 1000
set window 5

Now I am sure I'm using kermit protocol for downloading binary files. 
When I type loadb and disconnected on the serial console (Ctrl-\C),
then typed "send /bin /..." I get the following errors... :

************************************
SEND-class command failed.
  Packets sent: 2
  Retransmissions: 101
  Timeouts: 0
  Damaged packets: 0
  Fatal Kermit Protocol Error: Too many retries.

HINTS...
...
...


Are there special "kermit" settings for U-Boot/loadb (except for
enabling the command: CONFIG_CMD_DFL)?

Thank you very much.

Best Regards,

Rodel
