someone success with upload a file on BeagleBoard in u-boot yet?

I would like to know if someone success with upload a file on BeagleBoard in u-boot yet? If yes, please tell me how. I am trying to make kermit work but it seem cannot transfer the file.

Best regards,
Thang Nguyen

I've successfully used Kermit, Xmodem, and Ymodem. What version of uboot are you using, and what terminal program are you using for the upload?


I got the source of u-boot ver 1.3.3 from

I did try with both Minicom (using loads and select kermit) and Kermit terminal, but they just cannot transfer. I try to load the hello_world.srec file from example folder after build u-boot source to address 0x40000. I use Ubuntu.

Could you please tell me how to do it?

Thank you so much,
Thang Nguyen

There are known issues with Minicom and U-Boot kermit.
describes how to use the ckermit program for this purpose instead.
I have successfully used this method on beagleboard (and other platforms).



I did try with Kermit command method, but by some reason, it cannot transfer data after many times retrive.

So it will be help if you can tell me your real step to do it.

I highly appreciate your time.

You can use omap-u-boot-utils[1] for this purpose.

You need to exit from minicom before you run these commands

./ucmd -p /dev/ttyS0 -c “loadb” -e “bps”

This command prints the load address
./ukermit -p /dev/ttyS0 -f file_to_transfer


Thank for your information. I will try this.
