the selected configuration file: configs/stm32mp*_defconfig. options defined in Kconfig files (CONFIG_ compilation flags). Kbuild infrastructure (as in Linux Kernel, you can use make menuconfig in U-Boot). The U-Boot binary configuration is based on pass the control to the Linux kernel (or to another target application). COMPILE BOOT.ELF INSTALL
install the secure monitor (optional) or. load and check images (such as kernel, device tree and ramdisk). Execution of the boot command (by default bootcmd=CONFIG_BOOTCOMMAND):įor example, execution of the command bootm to:. Command execution through autoboot (CONFIG_AUTOBOOT) or console shell. Post-relocation initialization:(common/board_r.c): initialization of all the drivers. Relocation: copy of the code to the end of DDR memory. Pre-relocation initialization (common/board_f.c): minimal initialization (such as CPU, clock, reset, DDR and console) running at the CONFIG_SYS_TEXT_BASE load address. U-Boot executes the following main steps in DDR memory: USB: host (mass storage) or device (DFU stack). Display: LCD, HDMI, BMP for splashcreen. It supports the following features and commands:. It manages several internal and external devices such as NAND and NOR Flash memories, Ethernet and USB. It loads the kernel into RAM and gives control to the kernel. COMPILE BOOT.ELF SERIAL
It features a simple command line interface (CLI), allowing users to interact over a serial port console. U-Boot is the second-stage bootloader (SSBL) of boot chain for STM32 MPU platforms. loading and execution of U-Boot (or Kernel in Falcon mode : README.falcon ).Ģ.2 U-Boot: SSBL 2.2.1 U-Boot description. COMPILE BOOT.ELF DRIVERS
board_init_r(): initialization of the other drivers activated in the SPL device tree.

COMPILE BOOT.ELF DRIVER
board_init_f(): driver initialization including DDR initialization (mininimal stack and heap: CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN). SPL executes the following main steps in SYSRAM: There is no workaround for these limitations. SCMI support for clock and reset (not compatible with latest Linux kernel device tree). limited features (STM32CubeProgrammer / boot from NAND Flash memory). However, several known limitations have been identified when SPL is used in conjunction with the minimal secure monitor provided within U-Boot for basic boot chain. SPL is provided only as an example of the simplest FSBL with the objective to support upstream U-Boot development. SPL cannot be used for product development. It loads the SSBL (U-Boot) into the DDR memory. It performs the initial CPU and board configuration (clocks and DDR memory). It is a small binary (bootstrap utility) generated from the U-Boot source and stored in the internal limited-size embedded RAM. 
There are several ways to retrieve the U-Boot source code.The U-Boot SPL or SPL is an alternate first stage bootloader (FSBL). $ export CROSS_COMPILE=aarch64-linux-gnu-ģ. Then, configure your environment to access the Linaro cross compiler. Download and extract the Linaro toolchain. Intel SoC FPGA EDS 19.3 Pro Edition (only if planning to use U-Boot source code from SoC FPGA EDS)Ģ.Host PC running Linux ( Ubuntu 16.04 LTS).Otherwise the pre-compiled boot loader can be used as-is. This may be needed in case any changes are made to the boot loader.
