Wish I knew how to create drivers for OFW so it could boot from UBIFS. Normally I would encourage adding such drivers to OFW, but in this case I think it's wasted effort that could be much better spent in other ways. a) XO OFW already has well-elaborated partition support. It's

Another important advantage to partitions is that the existence of a boot partition isolates the firmware from changes in the filesystem used for the root. Advantage #2 that you cite below is also quite valuable - it makes it easy to preserve user data while replacing/recovering/updating the

Disk layout for XO-1.5

2009-07-27 Thread Mitch Bradley
This is a request for comments on a proposed disk layout for XO-1.5. XO-1.5 will have managed NAND instead of raw NAND, so we can use conventional filesystems instead of e.g. JFFS2. Proposal: The internal NAND storage will be partitioned with an FDISK partition map, into three partitions:

The filesystem is no longer internally compressed. The current size for the XO-1.5 system is 1.1 GB. 2 GB gives some headroom for growth and for temporary overages during updates. Walter Bender wrote: Why such a large system partition? -walter On Mon, Jul 27, 2009 at 6:17 PM, Mitch

The images come with olpc-update and the initramfs is ready to boot our special versioned layout filesystem (like 8.2 and previous). However the code to generate the images as the versioned layout is currently disabled because it exposed a bug in OFWs ext2 code. That bug is fixed in q3a06,

Now AFAIK, there's little to no Windows work being done in-house by the OLPC team, and it's all or mostly at Microsoft's side that the work's being done. At the moment, OLPC is doing approximately zero work on Windows. That wasn't true last year. I spent several months last year making

Even the OLPC wiki contains links [1] to misleading reports [2] about Windows on the XO without any further, clarifying comment. OLPCNews' quote of NN didn't make it clear [3] as well: For this reason, Sugar needs a wider basis, to run on more Linux platforms and to run under Windows.

As for speedups, I see 2 different ways : a) using a SD with a fat partition + ext2 filesystem b) using the nand with a fat partition + ubifs - this requires 2.6.29 which is not ready yet. A FAT partition will not work well on the raw NAND of XO-1, because of blocksize, erase block

From what I've read on the wiki, JFFS2 is here only because OFW doesn't know how to use UBIFS. Don't believe everything you read on a wiki. As Peter Robinson says, JFFS is used because it was the only viable alternative at the time we were doing the initial development. UBIFS did not
