Many of EMAC's ARM processor-based systems utilize NAND flash with JFFS2 filesystems. On these systems, the NAND flash is partitioned using the Linux MTD "Command line partition table parsing" feature. This allows the partition table for the flash to be specified on the kernel command line passed from the bootloader. By default, EMAC OE NAND flash images provide one partition for the root filesystem mounted read-only, and a second read/write auxiliary partition mounted on /root. This article describes how to modify the partition table and how to utilize and configure additional partitions.
