4. Boot Loader, U-Boot (Loader Binaries)
This chapter explains the boot loader and U-Boot in this package.
Note: Refer to 8.1.2
about how to build the source code of boot loader and U-
Boot.
4.1
Boot loader and U-Boot Images
The boot loader and U-Boot binaries are stored in the eMMC on RZ/V2M in advance. The bootloader and U-
Boot will be booted after powering on the RZ/V2M Evaluation Kit.
The following table lists the address information stored in the eMMC on RZ/V2M.

Notes: 1. The sector size is 512bytes.
2. Each file size is the file size of the loader binary file provided in this package. These file sizes may be different
from the loader binary files generated by bitbake. Also, the size of these files may change in future versions.
3. These RAM areas are not fixed because these binaries are stored in the local memory. After U-boot boots,
Boot loader and U-Boot will not use RAMA and RAMB.
4.2
Write loader binaries to eMMC
This section describes how to write loader binaries to eMMC.
Note: Use the eMMC writer only with the loader binaries provided in this package. Refer to chapter 7
“Flash Writer” when using the binary files generated by bitbake.
Note: If you use the previous version of the RZ/V2M Linux Package, rewrite the loader files to eMMC
with the following steps.
Step 1. Store the bootloader files to the FAT partition area on the SD card
Store the files shown in Table 4-1 to the FAT partition area.
Step 2. Board connection and terminal software setting
Connect the RZ/V2M Evaluation Kit to a Windows PC with a serial to micro-USB cable. Then, start a terminal
software (Tera Term) on the Windows PC. For setting up terminal software, refer to 3.2.2.
