MMC boot for 2008Os: what is the brand of your SD cards?
 

Apparantly Adata card 8G and above will require a low level formatting before cloning from the tablet, http://www.internettablettalk.com/fo...153#post137153, #289 and http://www.internettablettalk.com/fo...051#post137051, #24. Interestingly, Adata 4G SDHC can go straight without low level formatting while other report problems with 4G card, http://www.internettablettalk.com/fo...t=14637&page=2, #14 (what brand?). Or some have posted success by 'ghosting' from a previous working SD card, say a 2G card, onto 8G or above. Initial posting 1/08/08, http://www.internettablettalk.com/fo...ighlight=clone, and today is 2/03/08. This 'bug' plaqued/discouraged the cloning process for close to one month!

I would like to know from those have attempted, please post what brand, size, succeed (failed with err statements if possible).

__________________________________________________ ___
Here is mine (arrange from brands), LLF=low level format

Adata Turbo, 16G, succeeded after LLF, failed without LLF.
Adata Turbo, 8G, succeeded after LLF, failed without LLF.
Adata Turbo, 4G, succeeded without LLF
Adata 4G, micro in mini adaptor, succeeded without LLF (the card must be 'sit' rigidly, able to be read/write, it took me several trials to make it right)
Adata 4G, class 6, succeeded without LLF

Dane-Elec, 4G, succeeded without LLF

Kingston 4G, micro in mini adaptor, succeeded without LLF

Patriot, class6, 16G succeeded without LLF (Dan)
Patriot, 8G, succeeded without LLF (nhanquy PM)
Patriot, 8G, miniSD on SD adapter, succeeded without LLF ***** It will get corrupted after 1 month use, dont know why, happened to me 2X and happened to other user several times.

Sandisk Extreme III 4G, 8G (see thread #21, Geraldko) LLF may/may not needed
Sandisk 8 G micro w mini adapter, problems

Transcend 16G, succeed. LLF status unknown
Transcend class6, 8G, succeed without LLF (http://www.internettablettalk.com/fo...t=14637&page=2, #18; #22); worked for a while then die suddenly, suspect card problem, http://www.internettablettalk.com/fo...t=ghost&page=3, #21.

The above are all SDHC. Any card bigger than 2G are SDHC? I used mostly Milhouse script. I did try the Wiki by enterring commands one by one,
http://maemo.org/community/wiki/howt...from_mmc_card/, no dice, same results, failed if no LLF. So far, 2G/Kingston and 1G/Adata have been straight clone, no LLF needed.

Nobody use kingston or sandisk? Well, then this low level format use required by all except Patriot or maybe Transcend is critical to cloning in the N8x0 series. Is this from the SD, as 'conformed to the industrial standard' or rather another surprise from Nokia OS?

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

Is there a difference in the transfer rates between the cards?

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

Bun,

All my cards are class 6. I've never had problems with class 6.
class 2 gave me constant problems same with class 4. I have
Patriot class 6 , 16gb sdhc. I use many other class 6 brands, never had
problems with any class 6 cards. Hope this answers your pm. In regards
to your pm on my usb hub sdhc setup I provide
detailed instructions on this thread if you want a simple way to do it.

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

hi,
this is a stupid question but here goes. After cloning my OS2008 to MMC and Fanoushes dual boot program I'm not convinced that the OS is running from MMC.

I choose MMC from the boot option, the start up seems maybe slightly faster than before, but application manager installs everything on internal flash.

Is this just a default or is the OS still actually running from the internal flash.

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

how do you know that the app manager is installing software on internal flash?
what is the output of "mount" ?

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

There are many things one can check whethere your are booting from interenal flash or MMC. The most easy, control panel>memory, if the Device storage is >256 MB, you are booting from MMC, provided your partition, of course if more than 256 MB to begin with.


xterm df and look at 1st line, Filesystem Mounted on /dev/mtdblock4, you are booting from internal flash; all other you are booting from MMC, e.g., /dev/mmcblk1p2, boot from ext sd or /dev/mmcblk0p2, boot from int SD.

BTW, boot up from MMC and boot up from internal flash DO NOT communicate with each other, i.e., app installed on one is NOT accessible by the other.

I'm booting off of a 16 GB Trascend SDHC. Worked without any issue. Partition, format partitions, clone OS, booted up without an issue.

And the easiest way to ensure you're booting off of MMC instead of internal? Change your wallpaper. Shut down. Remove the SD card. Boot off of internal (you're only option). Voila, different wallpaper. :P

It should be noted that regardless of what you boot off of, your system volume will ALWAYS report itself as Internal Flash, even if you are booting off of MMC.

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

What do you mean by system volume?

bun

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

Whatever your boot drive/partition is. So on your typical Windows computer, you system volume is you C:. On your NIT, whatever you boot off of, be it internal flash or SD Card, will report itself as the same thing ("Device Memory" if you go to the Memory applet in the Control Panel). If I boot off of flash, my "Device Memory" (the system volume) is the internal flash. If I boot off of my SD card, my "Device memory" (now the system volume) is my bootable flash partition.

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

It is kind of obvious (of course with the wall paper too) if you go to memory section from control panel and look memory/device (to see how much memory you have when you don't have an xterm to use mount command).

Internal flash would not have more than 256M (for N800)!

@Phobos: After you install an app, watch the usage of the device memory.

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

I've successfully cloned with the SanDisk 4GB and 8GB Extreme III cards. In both cases I used low-level formatting with the Panasonic, but I don't know if that was necessary. (I've also cloned the OS to the MMC with a Transcend 8GB card.)

(Check out my signature if you want to make cloning the OS to the MMC an easier task.)


(This post used to say I thought you couldn't clone with SanDisk cards, but I was wrong. Hence in this edit I eliminated entirely what I'd written before.)

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

Apparantly, the tablet is having 'difficulties' in partioning SD card if it is NOT a 'virgin' card, ie., with exisiting Linux partition in particular. That explains why using PB's clone.deb, sometimes one has to do 2X, 3X, or many times and it may then get thru. I have the same experience when re-partition a SD card, even as low as 2G. I did it 4X under xterm/root/sfdisk, exisiting partition stayed. I finally took it to a PC and wipe out all the partitions and format into a Fat16, Panasonic or HP SD tools will do just fine, I then did the partition in the tablet. It went thru just like the way it supposed to do, right on the 1st time. I would not have the knowledge or energy to dig out more why the tablet is having 'difficulty' in partition with existing Linux partition, it is a job for the big guys, like qwerty/benson/PB/fanoush or whoever linux guru you are.

So my observation is, for 'virgin' SD cards, go thru PB's clone will just be fine. For a redo card, wipe out the linux partitions 1st then PB's clone.deb would be more successful then redo and redo.

BTW, I have put a link into wiki already, save GA a gentle 'reminder' :)

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

I think you may be making somewrong assumptions. When you partition the card you often need to reboot the tablet in order for it to see the altered partitions. If however you are re-running my script and the physical partitioning is not changing, it should work the first time.

This has always been my experience. Install the deb, reboot, install the deb, reboot it works.

I have only testing on kingston brand cards,
2gb mmc mobile, 8gb sdhc, 4gb micrsdhc

Re: MMC boot for 2008Os: what is the brand of your SD cards?
 

With existing partition, I have NOT been able to succeed on 1st run of the install tool.deb. But after wipe out the partition, I have always succeed on just one run. True, it is my observation over several months and it is an assumption.
