what do you mean by "go to" in "when I go to partition2 for mke2fs"? If you could post exactly what you're doing, and the responses you're getting, we can probably help.
Given that you're going to re-partition and re-format the card, it ought not to matter at all what state it is in prior to starting the procedure.

Hi, trying to move my OS 2006 to the RS-MMC in 770. I made it to the installation of e2fsprogs. I can't seem to install it from the xterm or the application manager. Any tips? I tried activating red pill mode and changed the distro to Gregale. When attempting install from xterm, I get the repeated error "ldconfig: can't open configuration file /etc/ld.so.conf: no such file or directory." Any advice?

MMC card problem, likely partition is not good. Get emelfm2, GPE filemanager, or diskUsage to look at the card before proceed. All are from maemo.org applications.

Point is that it looks like both partition table and FAT layout is tuned to be aligned with physical flash blocks. By creating random partition table, speed (and maybe even reliability and durability) may go down.
See this article for details
http://www.hjreggel.net/cardspeed/cs_calign.html
So maybe, if nupgrade.sh does the partition layout, it would be nice if it left at least the beginning of first FAT partition alone.
It is hard to know how important it is, maybe not much. YMMV
When I got my 8GB SDHC card I found that first 4MB of the card is 'wasted' and partition begins on block 8192. This is confirmed in the document mentioned above. There is perhaps some reason for this. I think this may be related to erase blocks and grouping of blocks for internal wear level logic. Maybe they try to prevent wearing off the beginning of the card (as it may contain some critical low level data).
This is a bit of black magic. If you are interested, start reading from page 66 of http://www.sdcard.org/about/memory_c...Layer_Spec.pdf
Looks like the size of Allocation Unit (AU) is 4MB for big cards. so it may make sense to aling beginning of partition at 4MB and data blocks after FAT table at 8MB.
Code:
sfdisk -l -uM
Code:
Device Start End MiB #blocks Id System /dev/mmcblk0p1 4 7821 7818 8005632 b W95 FAT32 /dev/mmcblk1p1 4 7819 7816 8003584 b W95 FAT32
EDIT: Milhouse (or other file system guru), as you can see above, my cards were factory formatted with 0B FAT32, but you suggest using 0C FAT32 LBA. Why?

N800 wuth OS2008.
uname -r returns 2.6.21-omap1 which seems right to me but I still got unable to locate mbcache.ko and carried on which trashed my partition because it was writing to itself. Ah well, I got it to work fine and thanks again for the brilliant script
I'll edit this post if I have more troubles... For now, it is working, so I think I'll let it go and come back in the morning.
EDIT: It all went well after that one problem! Thanks everyone!

I have corrupted my memory card. A reinstall shows now I have divided my flash into 2 partions instead of the memory car. I now cannot reflash my N700 to recreate the fs on the card. How do I restore the old boot menu to get into the device again?
Any help is appreciated....

I get a boot screen that I think is from fanoush asking -
Internal Flash
(Internal MMC card partition 2. ext2) N/A
(External MMC card partittion 2. ext2) N/A
USB Hard Drive
Power Off
Since MMC is Not available, it boots to flash and bypass the USB. I had the bypass with white sceen prior and cannot remember how I solved that. I have full access to the box with Putty from both Winders and Linux.

I'm having trouble following you. It sounds from your last post like you can boot from flash but your earlier post sounds like you can't. If you're trying to reflash, first question I have is: What happens when you're attached by USB to your Windows box and use the standard Nokia flashing utility?

Many thanks for the content in this thread. However is there any chance someone is working on summarizing it for the Wiki?
My problem is that I rarely get to dedicate much continuous time to the task of getting my 810 to boot from external flash
(or any other task)
For instance yesterday I sat down to go thru steps 1-6,
and in this thread and this thread there are over 580 messages for the similar problem.
I got hung up at step 6, had to download it three times. Had to repair/diagnose two external hard drives for my daughter, cook several meals, vacuum, repair the network connections for the house (a wireless usb AP went down) redo the BT keyboard connection (took over 30 minutes), take out the trash, fix a door, finish grocery shopping, and all in almost random order, oh - and charge the tablet.
Then at post #288 I see new instructions for nupgrade.sh, and am wondering what else is in the other 579 posts.
So - if it's going to be "wikified" soon I'll wait rather than try to keep the posts organized in my brain.
Again - thanks greatly for at least letting me realize the possibilities.

PLEASE use the Wiki
