Hi, I have a Kingston SDC4/4GB-2ADP : 4GB SHDC which shows write errors when access are not aligned on a boundary. I've first suspect a problem with the Freerunner has the problem only arise when booting from this SD card. But I've tested it latter with a USB card reader (Transcend M5) and found problems when random reading/writing on a partition. I've retried with 1MB aligned partitions and found that everything was going well. So aligning partition is not only a matter of performance, for some card it's also a requirement. To align partition with fdisk from util-linux use the following options: c - toggle msdos compatibility flag u - set unit to sectors instead of cylinder See for example: http://old.nabble.com/-ANNOUNCE--util-linux-ng-v2.17.1-td27685302.html Regards. -- Yann Droneaud _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
