DM7000s - Now booting the kernel

[faz666]

Hi Everybody,

I was given a DM7000-s last year and flashed it with a Gemini image "Gemini_420_DM7000_17122007.img" and it worked fine. I added a 7200rpm hard drive with a capacitor mod in the power lead, which worked fine for a while until it froze my dream box, so it was removed. I then used Dreamup and a null modem cable with "erase.img", the offical Dream Multimedia image "rel108.img", followed by an up button erase. It still freezes at the TV-System Wizard screen. On boot it hangs at ?Now booting the kernel?:

I have also successfully Jtaged the dream box using the 5 resistor 6 wire cable just in case the problem was the boot loader. The model I have is the one with the blue screen, this could be the issue as I have read this one has PSU issues.

The RAM check gives:

Installed RAM: 48 MB
Checking RAM between 0x00000000 and 0x01FFFFFF
Checking RAM between 0xA0000000 and 0xA0FFFFFF

Any ideas? I'm assuming some sort of hardware fault but I'm not sure what as I have read through the forums and tried all suggested fixes that were found inc. re-soldering the IDE connector on the main board for the hard drive.

Thanks for any help in advance.

The Dreambox is now working again, the Kernel was panicing, so when I saw:

Linux/PPC load: console=null root=/dev/mtdblock5 rootfstype=squashfs ro

Press "space bar"

Type: console=ttyS0,115200 root=/dev/mtdblock5 rootfstype=squashfs rw

And now it boots all the way.
