Flash Memory Devices for Booting

The memory controllers and devices that contain the boot loader image have configuration requirements
for proper boot from flash.
SD/MMC Flash Devices
The following figure shows an SD/MMC flash image layout example for boot. The master boot record
(MBR) is located in the first 512 bytes of the memory. The MBR contains information about the partitions
(address and size of partition). The preloader image is stored in partition A2. Partition A2 is a custom raw
partition with no file system.
