What is Linux MTD?

A Memory Technology Device (MTD) is a type of device file in Linux for interacting with flash memory. The MTD subsystem was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications.

How do I test my MTD partition?

Procedure

1. Determine the MTD ID of the device that you wish to partition. This can be done by running cat /proc/mtd on your target platform.
2. Determine the partition table of your device.
3. Pass the given command line to your kernel at boot-time using your bootloader.

How do I determine flash size in Linux?

2 Answers

1. Using sgdisk. You can use sgdisk to print detailled information:
2. Using /sys directly. You can also get those numbers directly from /sys :
3. Using udisks. udisks outputs the information directly.
4. Using blockdev. blockdev –getsize64
5. From /proc/partitions. grep ‘ sdb$’ /proc/partitions.

What is memory technology device (MTD)?

Memory Technology Device (MTD) is the name of the Linux subsystem that handles most raw flash devices, such as NOR, NAND, dataflash, and SPI flash. It provides both character and block access to these devices, as well as a number of specialized filesystems. The following devices are supported by the MTD subsystem:
