[SOLVED] Is Compact Flash supported by MTD subsystem?

Hi,

Is Compact Flash supported by MTD subsystem?

Can the MTD subsytem commands for formatting, partitioning, erasing, reading, writing,etc,.. be performed in Compact Flash like we do in NOR flash/Nand flash?

Please reply!

Compact Flash is not a MTD device. It has own Flash Translation Layer like USB sticks and mtd driver doesn't known how to communicate with this. Use normal tools, designed for hard drives for accessing CF.

I don't know what you mean by MTD. But AFAIK, the Compact Flash cards have their own controller onboard. They have an interface that is compatible to good old IDE/PATA. That's why you can connect CF memory cards directly to an IDE/PATA controller with nothing but a passive adapter in between. So you treat a CF card exactly like an IDE hard disk.

Most CF disks are really wired like an ide drive.

"MTD subsystem does not deal with block devices like MMC, eMMC, SD, CompactFlash, etc. These devices are not raw flashes but they have a Flash Translation layer inside, which makes them look like block devices. These devices are the subject of the Linux block subsystem, not MTD. "
