Booting Nucleus OS using Uboot
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
