Re: [U-Boot-Users] Loadb issue
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

Please do not post messages in HTML format to this list.
- at u-boot command prompt gave following command => loadb 0x60008000 115200
- From hyperterminal, Transfer->send file with protocol as kermit,
selected the file and tried sending, but failed. Everytime hyperterminal poped up "error limit exceeded".
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 Andreas Schweigstill

And STOP sending HTML!!!!
PEGASUS # loadb 0x60008000 115200 ## Ready for binary (kermit) download to 0x60008000 at 115200 bps...
from HOST PC [root@localhost s3c24x0_uboot_dev]# cat ../hello_world > /dev/ttyS0 [root@localhost s3c24x0_uboot_dev]#
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.
NOTE: got some junk data when cat the binary file....seems like u-boot is trying to print the data it is receiving, on the console
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When used with kermit:
...
(/root/) C-Kermit>send /home/banajit/pegasus/s3c24x0_uboot_dev/u-boot.bin
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!!! See http://www.denx.de/wiki/view/DULG/UBootCmdGroupDownload

Thanks for the pointer. Will maintain it in future.

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!!!
I am following the same procedure as mentioned.
Thanks and Regards Banajit

Similar may be not good enough.
I am following the same procedure as mentioned.
Then it will work, a it does here.
