Re: Distributios: boot image, Linux OS image, SD card format

Thu Feb 23, 2012 4:29 am

Ok, from what I've read we need a Boot Image on some FAT partition.

and an OS image on some other type of partition.

Again from what I've read the boot image is small and the OS image is about 2Gig give or take.

So, what size is the FAT partition?

What size is the OS partition and what type?

Some portion of the SD card or the whole thing?

EXACTLY what are the parted commands to create the partitions?

EXACTLY what are the dd commands to move the images to the SD card?

Someone needs to put this information in a compact, easily understood format in the distribution site.

Just saying...

I should just delete this topic since you can't bother to read the pinned sticky at the top of the Distributions forum.  But I will move it instead.

There are already posts on this you should try the search function.

FAT32 is 75MB.

Then there are two other partitions of 1.55GB (I'm guessing EXT3 or EXT4 OS partition) and 191MB (probibly Linux swap.)  I'm not booted into Linux right now so I can't say.  I can tell you the commands I used, click click...wait done all through the GUI no tears were shed.

Since there is no device right now does it matter?  No, this info will all become avalible when the device comes out.  Then like any community project you can go to the wiki and post that EXACT information yourself (but since you are too lazy to even read the pinned topic at the top of this forum I'm guessing someone else will put that info into the wiki.)

the partition table on the Debian Squeeze image is as follows:

Number Start End Size Type File system Flags
1 1048576B 79691775B 78643200B primary fat32 lba
2 80740352B 1747976191B 1667235840B primary ext4
3 1749024768B 1949302783B 200278016B primary linux-swap(v1) The units are in bytes. The partition table for others images may be totally different of course. You don't need to use parted to "create" a partition table, it's already there in the .img file, you just need to write the img file to an SD card and that's it.
