as an SDK for application development.
All the documentation for the developer is available from:www.yoctoproject.org/documentation.
12.2
The bootloader procedure
The bootloader procedure is the following:
1. The MLO file is loaded from either the external microSD card or the onboard eMMC memory, and
saved in the on-chip memory to configure the RAM memory for use
2. The u-boot.img file is loaded (from the same device where MLO was loaded from), saved in the
RAM memory, and executed
3. The bootloader searches for a valid operating system. The search order is:
a. microSD card
b. eMMC
4. The bootloader fetches the Linux kernel (/boot/zImage) and the device tree (/boot/reliagate-1011.dtb), and boots the operating system up
12.2.1
How to select the MLO source
The MLO file can be loaded from either the external microSD card or the onboard eMMC memory,
according to the setting of the Boot selection jumper (JP2):
JP2 inserted = MLO file loaded from the micro-SD card
JP2 removed = MLO file loaded from the eMMC and, if not found, from the microSD card
12.2.2
How to set up a correct microSD card / eMMC card partition
To allow the correct bootloader procedure, the microSD card and the eMMC memory have to be configured
with at least these 2 partitions:
1st partition:
o Type: FAT16
o Flags: lba, boot
o Contains the files: MLO and u-boot.img
2nd partition:
o Type: ext4
o Contains the operating system, including the Linux kernel (/boot/zImage) and the device tree
(/boot/reliagate-10-11.dtb)
