Hi Guys,

My question is a bit different on the way the beagleboard write the uImage on nand. In beagleboard, in order to write the uImage in flash is to boot the board on SD card and from there, it can access the nand for programming. The other way that I want to do is I want to send the uImage to u-boot using serial connection and I would like to know if it’s possible to do that?

Any theory?

Thanks,

John

Hi!

don’t know about BB but I did this on a different platform. I suppose the u-boot functionality is the same

Hi,

Yes, you can use kermit or xmodem over the serial connection. Or you can load raw s-record file.

Command you are looking for is “loadb”.
