Hi Finegan,
I am coding the firmware for usb mass-storage, will drive 3-types memory card:
Compact Flash, Smart Media Card and SD card.
I tried CF on Windows 2000 SP1/SP3 and iBook Mac OS X v9.1 is work well.
Currently, I tried to make it work on Linux, RedHat v7.3 with Kernel
"2.4.18-3", but met problems.
1. # mount /dev/flash1 ==> I got "mount: /dev/sda1 is not a valid block device"
2. # mount /dev/sda1 /mnt/flash1 ==> I got "mount: /dev/sda1 is not a valid
block device"
3. # fdisk /dev/sda ==> I got "Unable to read /dev/sda"
4. # fdisk /dev/sda1 ==> I got "Unable to open /dev/sda1"
Please help me to find out what I missed. Thanks!
Following messages are what I tried:
