The 512K SanDisk card that came with my Neo mounts automatically. 'mount' gives this : /dev/mmcblk0p1 on /media/card type vfat (rw,sync,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1) So you can see it is preformatted with a vfat-compatible filesystem I have tried with a couple of kernels and rootfs - see http://wiki.openmoko.org/wiki/User:Dcorking - the vfat and sd drivers and the automount magic were included in the ones I tried. To save taking the cover off the phone, I wrote to it with 'scp'. Since the phone is USB 1.1 it will be quite slow. Unfortunately, when I tried on Monday, scp exited without an error (that I recall) at 368k of a 3M file. Today the whole 3M file transferred (and the md5 fingerprints match.) I don't know if u-boot can boot a kernel from vfat, but if not, mke2fs is included on the phone. > > Just out of curiosity, what issues have you seen with a 2GB card?

Kingston cards may not be compatible yet - see for example: http://lists.openmoko.org/pipermail/openmoko-uboot/2007-February/000012.html I seem to recall someone mentioned concern about sizes over 1 GB, but I can't put my hands on any documented rumours.
