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:
$ 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 should be programmed at address 0x1D200 in the QSPI Flash.
