Good idea. Perhaps something that wiped the partition table and other stuff at the start of the drive. If I knew exactly how the problem was caused, I'd recommend something, but I've missed the reproducer. I admit, a full erase did fix a problem like this for me earlier last month. -- James Cameron ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Mitch said: > fdisk + mkdosfs is a mistake-prone combination. That's probably what I screwed up ages ago. It might help if the wiki section had an example of something known to work - that is take a USB flash drive in unknown state, erase everything, and set it to a good state. The corresponding mount command would probably be handy too. I'm probably assuming that everybody is using a RedHat style linux, or something close enough. It may be worth recording the distribution (and version) just in case that matters. -- These are my opinions, not necessarily my employer's.

That would be great. I have a 2GB USB disk that used to be as a rescue boot disk. As syslinux doesn't support >1GB, I need to partition it into two FAT16. The olpc firmware doesn't seem to like it and every time I need to specify the boot-device under OK prompt to do the update. However, later I noticed that actually I only need to go to the OK prompt and type boot would be sufficient. (USB icon only appears if boot from OK prompt.) This makes me wonder that if the problem is due to the partitioning (I'd prefer to keep my present partitions) or the USB detection? > The problem is actually a little more complicated than having a > partition table or not.

Re: Unable to update my machine
The problem is ostensibly fixed in a new version of firmware that will be released in the next couple of days. The problem is actually a little more complicated than having a partition table or not. There was a situation where a disk could appear to both have a partition table, and also have a FAT file system starting in the first sector. The way that can happen is if you use mkdosfs on the raw disk (sda), and then change your mind and use fdisk to partition it and then do mkdosfs again on sda1. fdisk does not automatically erase the BIOS parameter block (the FAT equivalent of a super block) in the partition sector, so you end up with an ambiguous situation where the first sector looks like an unpartitioned FAT volume and also a partitioned volume at the same time. I tried to correct that problem, but in the process I managed to break the case where there is an unpartitioned FAT volume that has the extended form of BIOS parameter block. I think I have now fixed that breakage... At least I hope so. fdisk + mkdosfs is a mistake-prone combination. Philip Macpherson wrote: > It now works.

I formatted so I had no partition and then open firmware was able to read it. Maybe this should be mentioned on the wiki.

Re: Unable to update my machine
Philip, It sounds like you have tried a lot of things, but you don't mention downloading the latest copy of olpc-auto.zip, which is required these days. This file has been updated quite a few times recently so the latest version should be downloaded whenever you get a new build. The Autoreinstallation page of the wiki is very detailed and also has been updated quite a bit in the last few weeks to help people with installation. If you haven't read through that page carefully in the last few days, please start there and follow the instructions carefully. Over time this will get easier and it won't change with every build... but since we added the ability to backup and restore and the activation key, it has taken a number of weeks to get this process stabilized. If you HAVE carefully read through the autoreinstallation page and you are still having a problem, then we may need to see your machine or maybe we can go through the installation together on irc.

Unable to update my machine
To Devel list I've got a b4 which I've upgraded once when I first got it and am unable to update since. I'm using the same usb flash key as I used the first time. I first tried it unsuccessfully with all the files the same except for updated firmware . Since then I've tried multiple times with the same files and later with the newer firmware and newer build. I've also tried re downloading the files along with reformatting the stick (as both FAT 16 and 32)to see if it helps. When I insert the stick and turn on the machine with the x key pressed it recognises the key is there but doesn't seem to see the script. As it doesn't mention that it's either upgrading the machine or if it's firmware is current. The only difference I see after this happening is the usb stick now has a folder on it called .olpc.store The usb stick has only one partition and as far as I know sector sizes of 512 (fdisk didn't tell me otherwise when I loaded the stick with it). I have build 542, q2c22 currently installed and have tried installing q2c25, both on it's own (with 542 still being in the boot folder) and with the newer build 558. But have failed as described above. Thanks for your help, Philip P.S Sorry for the grammar, it's really late ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
