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:

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.

Hi faz,

Sorry to hear of your problems.
I've not had any experience of hardware faults with my DM7000S so I'm not sure whether your problem is hardware or not. Certainly I would try re-flashing. I would probably try a newer CVS image. The DMM 108 image is very very old and the Gemini 420 that you were previously using may well have updated the Front Processor. This could possibly give problems with booting an old Kernel such as a 108 image.
Failing that you could try another Gemini (I am running 4.60 in USB Multiboot). I don't like changing my flash image (too risky for me!!), so I try various images in Flashwizard USB multiboot (much safer).

Hope you get it fixed.

Best wishes, john.

BTW, I tried to upload a CVS & a Gemini for you but both failed, I see now that ZIP files are limited to 4.81MB and both are bigger, sorry.

faz666

Thanks for your advice John.

I have downloaded rel110-20070219b.img and Gemini_0460_DM7000_20122008.img, I will try flashing them tomorrow and let you know how it goes.

Hi All,

Used DreamUP_1_3_3_0.exe with erase.img, then rel110-20070219b.img followed by an up button erase and it still hung on "TV System Wizard"

Used DreamUP_1_3_3_0.exe with erase.img, then Gemini_0460_DM7000_20122008.img followed by an up button erase and it still hung on "TV System Wizard"

I have also posted on Sat Industry and Digital Kaos with no feedback.

The FP seems to be 1.10 now, anyone got any ideas?.

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.

Hi faz,

Well done!
Glad you've got it sorted.

Why not go on to set up FlashWizard Multiboot on a USB memory stick?
Even though you may not want to run lots of images, it's still loads safer changing images in USB rather than Flash! If anything goes wrong you just boot the Flash image or a working USB image, remove the faulty image and try again or another new image.

Best wishes, John.

faz666

Thanks for the advice John,

I'm going to give that a go next and preserve my flash.
