[U-Boot-Users] booting with a multi-image and DTB on powerpc

[Gregoire Banderet]

Hello,

Using u-boot 1.2.0 and Linux kernel 2.6.20, I try to boot a powerpc 
board. I have a working DTB file and a multi-image file with uImage and 
the initramfs.
I am able to boot with a separate uImage and a NFS rootfs like this:
setenv bootargs root=/dev/nfs rw nfsroot=3.137.218.190:/rootfs 
ip=3.137.218.182:3.137.218.190:3.137.218.1:255.255.255.0:disco405:eth0 
console=ttyS0,115200n8
tftpboot 2000000 /tftp/disco405.dtb
tftpboot 1000000 /tftp/uImage
bootm 1000000 - 2000000

But I am not able to boot using my uLinux-initramfs.img multi-image.
setenv bootargs root=/dev/ram 
ip=3.137.218.182:3.137.218.190:3.137.218.1:255.255.255.0:disco405:eth0 
console=ttyS0,115200
tftpboot 2000000 /tftp/disco405.dtb
tftpboot 1000000 /tftp/uLinux-initramfs.img

... what's the correct bootm command?
"bootm 1000000 - 2000000" does not work.

Thanks,
Greg
