Sample MTD Driver for NOR Flash - Embedded Linux Development

WebThis patch implements memory accessor interface in the MTD layer which enables the kernel to access flash data. This patch adds two new members to the mtd_partition structure, a function handler which will be called during setup of the partition and an argument to be passed to this setup function. Example: WebApr 24, 2008 · To MTD-enable your device, your first task is to tell MTD how to access the flash device. For this, you have to map your flash memory range for CPU access and provide methods to operate on the flash. The next task is to inform MTD about the different storage partitions residing on your flash.
