1/ If you please out line the purpose of all three images in terms of their usage. (image version 1.0.
2/ boot-cramfs.img ???
3/ complete-neutrino.img ???
4/ root-neutrino-squashfs.img ???
I have no Idea what "image version 1.0.8" is. But boot-cramfs.img is the CRAMFS image, which contains the kernel, root-neutrino-squashfs.img is the SQUASHFS image of the root filesystem and complete-neutrino.img is both images contained.
5/ I checked DM7000 directory structure particularly /proc/mtd. No such directory exist in the /proc/
If there is no /proc/mtd file, then your machine is seriously broken and you shoul consult someone who knows what he is doing. How did you check if there is a /proc/mtd file?
6/ Currently I have few images from different image-makers i.e. 2Gether Strombreaker, Gemini, BoxMan plus some others etc they all tend to have single image file which I assume embedded above all three images. Time to time I flash these images in to DM box and they seems to work; using third party utility such as Dreambox Control Centre and DreamUp. these third party utilities seems to work effectively; along with ftp- ing image into /tmp directory with squashfs extension.
7/ Initially I am planing to flash the DM box using these utilities or relies (on FTP, telnet rare case) etc; these utilities make life lot easier as currently I do not have serversupport and DHCPd, BootTP NFS facility main network come into disrepute. but some stage (tangible) time frame I may setup boot server to boot the box from server and test the image, which surely need extra hardware, as walking on tight budget and initial hurdles yet to over come. My engagement into this project are very recent one and going through lot of learning curves to understand the DM7000s as it inner working and mainly prototype point view.
I'm not sure you can boot a dm7000 without some knowledge which you obviously don't have. At least with the dm500, netbooting is quite finicky because of the boot loader which is not really suited for it.
8/ Experience shows a stable good image may bring back DM box in to OS control after flashing with an image and DM box work but in the case some bug proof image or dodgy image create a complete shut down of system hence serial port is only the life line to DM box to bring back in to its default/normal stage, as I flashed many different images from various above aforesaid sources.
I have no Idea what you want to express here.
9/ I will appreciate if you briefly out line the procedure of these three images and their flashing viability as debugging and testing point of view
It depends on what you want to do. I usually do only update the root image, because the kernel normally does not really change, but...
...I only use self-built images, so I *know* that my kernel did not change. So for you it is best to take the complete image and flash it into /dev/mtd/X with X being the number from /proc/mtd (which you claim your box does not have) and which corresponds to the "complete flash without bootloader" or "cramfs + root" partition (I'm not sure about that because I don't have a DMM box powered up).
I use the fcp tool to flash the images, like "fcp -vr /tmp/complete-image.file /dev/mtd/X", but you need to have the tool on the box, I'm not sure if your images have it. You can still copy it there, it gets built with "make flash-fcp" and then is in cdkroot/sbin/fcp. But you should know what you are doing, flashing the image into the wrong partition will make your box unbootable.
10/ Is it possible using RJ45 (cat 5) cross over cable to connect DM 7000 box direct development computer and set up serversupport facility for booting and testing image.... If it is possible where I can get these info (in English, please) and how to set up boot server faclity using RJ45 cable.
Well, you need to find out which commands your boot loader has for booting via network (you probably need a serial cable to give commands to it) and then you need to give it the apropriate options. I don't have a dm7000, so I cannot help you.
An alternative is only changing the kernel command line (booting the kernel from flash, but giving an NFS root filesystem), there are lots of Linux-NFSboot HOWTOs on the net, so you can try to follow them.
