Overview

The U-Boot bootloader is used for low-level initialization and operating system loading.

Building U-BOOT for RNX-RZG2UL-OSM

This U-BOOT is based on https://github.com/renesas-rz/renesas-u-boot-cip, branch v2021.10/rz

Set up the cross-compiler and CPU architecture

$ export ARCH=arm64
$ export CROSS_COMPILE=/opt/cross/aarch64-ronetix-linux-11.1/bin/aarch64-ronetix-linux-gnu-

Cross-compiler can be downloaded from here: http://download.ronetix.at/toolchains/crosstool-ng

Clone the latest revision of the repo

$ git clone https://github.com/ronetix/u-boot.git u-boot-ronetix --depth=1 -b v2021.10/rz
$ cd u-boot-ronetix

Configure

$ make rnx_rzg2ul_osm_defconfig

Build

$ make

Build Results

File Name Description
u-boot U-BOOT ELF image used for JTAG debugging
u-boot-dtb.bin U-BOOT image with DTB

Create FIP image

Create a new Firmware package fip.bin that contains BL31 and U-BOOT.
The BL31 image is part of the ARM trusted firmware package - see here how to build it:

$ cp ../arm-trusted-firmware/tools/fiptool/fiptool .
$ cp ../arm-trusted-firmware/build/g2ul/release/bl31.bin .
$ ./fiptool create --align 16 --soc-fw bl31.bin --nt-fw u-boot.bin fip.bin

Programming the FIP image

The FIP image file ./fip.bin should be programmed at address 0x1D200 in the QSPI Flash.
