> how to upgrade the SD card ? All you have to do is "stick the new card in", then perform the 'fs-update' (with an appropriate-sized .zd image). The ENTIRE SD-card-content will be written-over-anew, including the partition table.
---- The catch is that the micro-SD card is beneath the heat spreader - and once you replace the card, you have to make sure that the heat spreader has thermal contact with the CPU chip. [I suspect that "too much physical pressure at the CPU chip" might have contributed to the #10314 failures of some pre-production XO-1.5 motherboards.] ---- > a fresh new 8GiB micro-SD card I had good luck with a 8GiB micro-SD card in the 2009 XO-1.5 I had (but that system eventually stopped working - I don't know if my having put in a different micro-SD card had any relationship to that failure). What appears to matter most with the micro-SD card is its SPEED (it would take a heck of a lot of Journal entries to fill even a 4GiB card). There was a discussion on the devel list a long while ago about the transfer speeds measured on the XO-1.5 with several different cards -- apparently NOT ALL the available cards met OLPC reliability specs. mikus _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
