[U-Boot-Users] Booting Nucleus OS using Uboot

[Shiju Mathew]

Hello,
I am tryng to boot Nucleus OS using uboot. I tried the raw binary and
elf image format , but could not boot the OS. I could boot the OS using
the RVI debugger. To boot the binary image I just load the image to a
RAM address and called the "go" command. For elf I used bootelf command.
Has anyone have tried to load  Nucleus though U-boot?

Thanks,
Shiju

You Just need to create a U-Boot Image with mkimage and specify your load
address and the entry point.

If you use tftpboot to load your image as follow
tftpboot 0xA0000000 /tftpboot/image
And to boot go 0xA00000020

Your load address is 0xA0000000
Ans your entry point is 0xA00000020

 tools/mkimage -A your-arch -c none -T firmware -a 0xA0000000 -e 0xA00000020
-d image image.bin
