NAND flash ought to be a lot faster than Glamo's MMC interface. Where is the bug? FWIW, I tried a simple hdparm run on NOR flash, NAND flash and SD card: r...@debian-gta02:~# hdparm --direct -t /dev/mtdblock0 # NOR flash /dev/mtdblock0: Timing O_DIRECT disk reads: 2 MB in 1.24 seconds = 1.61 MB/sec r...@debian-gta02:~# hdparm --direct -t /dev/mtdblock3 # NAND flash /dev/mtdblock3: Timing O_DIRECT disk reads: 8 MB in 2.89 seconds = 2.77 MB/sec r...@debian-gta02:~# hdparm --direct -t /dev/mmcblk0 # Glamo MMC /dev/mmcblk0: Timing O_DIRECT disk reads: 8 MB in 3.46 seconds = 2.31 MB/sec -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
