Writing Bootloader
For the boot operation, two boot loader files need to be written to the target board. Corresponding bootloader files and
specified address information are depending on each target board as described in
Table 4
.
“XLS2” command of Flash Writer is used to write boot loader binary files. This command receives binary data from the
serial port and writes the data to a specified address of the Flash ROM with information where the data should be
loaded on the address of the main memory.
For example, this part describes how to write boot loader files in the case of RZ/V2L Evaluation Board Kit PMIC
version.:
