Boot from 2gb Card
 

so i am new still and waiting for the 770 to show up but trying to read some info, am i getting this right....the articles on booting from MMC card reference a 1gb card at the time there weren't any 2gb cards so i can do the same steps for the 2gb and get more storage. so i assume i use a 2gb to replace the 64meg that comes with the unit. does that mean i can add an additional 2gb to the additional memory slot or am i just missing it all together, any thoughts or suggestions i gladly welcome.

Thanks all for the time. and look forward to hacking the 770.

I did this the other night. If you are following the EASIER guides, you can follow the procedure almost exactly. When you set the partition sizes, simply adjust it as you'd like. Keep in mind that the MMC2 partition is where you will be installing apps. Essentially you are taking directories in flash memory and pointing them to directories on the MMC2 "device". You can then still have an MMC1 partition that is accessible from other operating systems.

I"m a bit confused by how to enter one command:

# sfdisk /dev/mmcblk0
/dev/mmcblk0p1:1,15000,6
/dev/mmcblk0p2:15001,,
/dev/mmcblk0p3:
/dev/mmcblk0p4:

Should there be returns after each line? Spaces? Or should it all be run together?

Thx

Re: Boot from 2gb Card
 

just finished doing this right now.. works fine..

one thing
# sfdisk /dev/mmcblk0 <-- this is one command

then it says loads of crap
then you'll be at a prompt like:
/dev/mmcblk0p1:

then you put in 1,15000,6
another thing.. this is where you set how big you want each partition
SO if you have a 2gb card, you're giving 1.5gb to the OS.
Which is TOTALLY unnecessary.
the 15000 is the size of the partition for the 'Memory Card'
whatever size you make this is how big the device will say your memory card is.
the rest will go to the OS, for installing programs and the OS itself.
for my 2gb card i used 1,45000,6 and got over 300mb for proggys and 1.37gb for the memory card.
just make sure you change the second set to whatever you put in the first PLUS ONE.
so if you did:
/dev/mmcblk0p1:1,45000,6
THEN
/dev/mmcblk0p2:45001,,
THEN leave mmcblk0p3 and 4 blank.

Thanks VERY much, Trencher!!

Re: Boot from 2gb Card
 

Based on what I"m reading - I'm wondering if the 1 Gig card I bought (for 15 bucks mind you - so no big deal) was a waste.. It sounds like the 2 gig card is really what's needed if you want to do anything with the unit (such as put 2007HE on it). Is that a correct statement, or can you get away with it on the 1 Gig?

On top of that - I've now noticed that there are MMC Plus cards (reading other posts and looking outside of NewEgg). Are these cards usable in the device? Are they worth it? (seems like they might be from reading around)

Tnx - (newbie who bought from Woot! )

MMC Mobile cards are much faster than regular RS-MMC cards. See here: http://fanoush.wz.cz/maemo/#mmcplus
NOTE: I previously said MMC Plus. Those won't fit in the 770. I meant to say MMC Mobile. http://www.sandisk.com/Products/Cata...ile_Cards.aspx

Re: Boot from 2gb Card
 

well, depending on what you want to do, 1gb should be fine. if you give the os 500mb, that's still 500mb for media, way bigger than 64mb. and you'll still have almost limitless space for installing apps, which will take no space on the media partition. i find that reencoding videos makes them run much faster, and it comes out to about 50mb for 20 mins. easily fit a couple of movies in 500mb.

Re: Boot from 2gb Card
 

So If I were to choose between these two, which one would be best?

mmc, or mmcplus

There's also a 4 gig mmcplus, will that one work with the n770?

Thanks in advance.

Re: Boot from 2gb Card
 

Won't both of those stick out from the 770? I can't imagine wanting to have 1/2 a flash card hanging out of my 770, not to mention you couldn't put the hard case back on to put it to sleep.
