[U-Boot-Users] Remote Kermit Not Responding
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?

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

Did you read what I replied to you first question? I don't like repeating myself.
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?
In other words: are you sure you're using kermit BINARY protocol for sending?
This is most likely a usage error. See the manual for instructions how to configure Kermit.
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
