the mmc partition is wrong, i can make a partition with mkfs.vfat -F 32 /dev/mmcblk0
i can mount this partition but it isn't recognised in the nokia 770 file manager...
i can't mount partition via usb, it say there is no card...

the default partition is /dev/mmcblk0p1 so i think there is a primary partition created with fdisk. But there is no fdisk on nokia 770 :'(
What can i do ?
