I've just released OFW Q2E24 ( http://wiki.laptop.org/go/OLPC_Firmware_q2e24 ) which is a test candidate for the upcoming 8.2.1 release. There are a couple of things that could use some testing, so I'm soliciting help.
Firstly, if you have 2 or more XOs and are willing to overwrite the NAND FLASH on one of them, you could test the NANDblaster, see http://wiki.laptop.org/go/Multicast_NAND_FLASH_Update . Secondly, if you have a USB CD-ROM drive, you could help me by testing it with OFW. To do so: a) Remove all other USB storage devices (FLASH keys and the like) from the XO b) Put a CD-ROM that has an ISO-9660 filesystem (the standard CD-ROM filesystem) in the drive c) Plug the drive into the XO d) Power on and get to the ok prompt in the usual way d) Type ok dir u:\ If it works, you'll see a directory listing, perhaps after several seconds (CD-ROM drives can take a long time to spin up and read the disk's table of contents). If it doesn't work, it might hang, or it might say "Can't open directory" and perhaps even "Can't open disk label package". If it fails, there are a couple of other things to try that would give me useful information: 1) Look in the "USB2 devices:" list to see if there is a line like: /pci/u...@f,5/s...@1,0/disk' That's the CD-ROM assuming that you have removed all other USB storage devices. It might be "s...@2,0" or "s...@3,0" depending on which USB port you used. 2) Power off then back on, get to the ok prompt and type: ok dev u ok : max-transfer 800 ; ok dend ok dir u:\ That patch reduces the transfer size to one CD-ROM sector, so the driver doesn't do read-ahead of large chunks. That shouldn't make a difference, but I have one CD-ROM drive that flakes out with long transfers while working okay with short ones. I'd like to know if that is a common problem or just a bad drive.
