Well, here's an odd thing. I already had FS debug on of course, but not the informational output. Turn that on, and I can now actually create a FAT volume on /dev/ram0. Cannot explain that (console output below). Tried running msconn with /dev/ram0 but it still crashes. It *seems* to be printf statements in the msconn system app itself!!?? nsh>mkrd 64 mkrd: RAMDISK at 0x20074cd0 ramdisk_register: buffer: 0x20074cd0 nsectors: 64 sectsize: 512 nsh>mkfatfs /dev/ram0 bchdev_register: blkdev="/dev/ram0" chardev="/dev/tmpc000001" readonly=F find_blockdriver: pathname="/dev/ram0" rd_open: rd_crefs: 1 rd_geometry: Entry rd_geometry: available: true mediachanged: false writeenabled: true rd_geometry: nsectors: 64 sectorsize: 512 rd_geometry: Entry rd_geometry: available: true mediachanged: false writeenabled: true rd_geometry: nsectors: 64 sectorsize: 512 mkfatfs_clustersearch: Configuring with 1 sectors/cluster... mkfatfs_tryfat12: nfatsects=1 nclusters=29 (max=341) mkfatfs_tryfat16: nfatsects=1 nclusters=29 (min=4081 max=256) mkfatfs_tryfat16: WARNING: Too few or too many clusters for FAT16: 4081 < 29 < 254 mkfatfs_clustersearch: WARNING: Cannot format FAT16 at 1 sectors/cluster mkfatfs_selectfat: Selected FAT12 mkfatfs_configfatfs: Sector size: 512 bytes mkfatfs_configfatfs: Number of sectors: 64 sectors mkfatfs_configfatfs: FAT size: 12 bits mkfatfs_configfatfs: Number FATs: 2 mkfatfs_configfatfs: Sectors per cluster: 1 sectors mkfatfs_configfatfs: FS size: 1 sectors mkfatfs_configfatfs: 29 clusters mkfatfs_configfatfs: Root directory slots: 512 mkfatfs_configfatfs: Volume ID: 00000000 mkfatfs_configfatfs: Volume Label: " " /* lots of rd_write messages to the sectors.
