What is SoC boot?
Introduction : Boot process is the process in which any SoCs takes various device configurations (trim bit, device security settings, boot vector location) and memory initialization (like FLASH/SRAM/GRAM) is done after reset lifting.
What is a bootloader FPGA?
The TinyFPGA USB Bootloader is an open source IP for programming FPGAs without extra USB interface chips. It implements a USB virtual serial port to SPI flash bridge on the FPGA fabric itself. Commands to boot into the user configuration or access the SPI flash are all transfered over this interface.
What does a SoC bootloader do on a FPGA?
SoC Bootloader Intel® SoC FPGAs use a bootloader to load and run the end user application on the hard processor system (HPS). The end user application may be a simple bare-metal application or a complex operating system like the Linux* operating system.
What kind of bootloader does Intel SoC use?
The Minimal Preloader (MPL) is a bootloader developed using the Intel SoC FPGA Bare-metal Hardware Abstraction Libraries (HWLIBs). It is a single-stage bootloader designed for minimal footprint. The MPL is offered with a Berkeley Software Distribution (BSD) license, which allows more convenient development and deployment.
Which is primary core in multi core SoC?
In the boot process various modules/peripherals (like clock controller or security handing module and other master/slaves) initialized as per the SoC architecture and customer applications. In Multi core SoCs, first primary core (also called booting core) start up in boot process and then secondary cores are enabled by software.
How does a multi core SoC boot from PSA?
CORE will execute the Image/.hex from PSA which is likely to load at SRAM/GRAM or FLASH as directed by Boot Loader. The loading of Image/.hex into memory (FLASH/SRAM/GRAM) is done by boot loader. This loader can be inbuilt with BOOT ROM or can be external loader.
