Hi,

As Wolfgang Denx has pointed out you can use the low boot option when building. Put the binary image on your tftp server and set up dBUG to download the u-boot binary image through tftp with the dn command. Then use the dBug fp command to burn the image to low boot flash An example for a 16Mbyte MPC5200 Lite card:

fp FF000000 FF035250 20000

where "FF035250" will have to be adjusted for your image size. "20000" is where the image ends up in RAM after tftp download.

I had problems using tftp at 100Mbps but these problems vanished when I put a 10 Mbps hub between the 5200lite and the rest of the net, forcing the ethernet to 10 Mbps, half duplex.

Kind regards,

Tord

Howdy all,

Is there a way to load U-Boot from another bootloader?

I would like to be able to load a development version of U-Boot from the Motorola dBug on my MPC5200 board.

Thanks,
