The bootstrap procedure of the u-boot bootloader involves:
1. Relocating the binary from flash/ROM to DRAM without adjustments through memory remapping.
2. Performing a general relocation of the binary in DRAM which involves adjusting addresses.
3. Initializing hardware and memory before jumping to the main initialization code.Linux Porting

This document provides an overview of porting Linux to a new ARM platform. It discusses setting up the GNU toolchain, kernel prerequisites and configuration, creating machine-specific files and code, initializing drivers and boot options. Key steps include registering the new machine, adding architecture-specific code and configuration files, initializing I/O mapping and IRQs, and creating an initramfs image to test bootability. References for further information on ARM Linux boot sequences and porting are also provided.Uboot startup sequence
Uboot startup sequenceHoucheng Lin
?
U-boot provides a multistage boot process that initializes the CPU and board resources incrementally at each stage. It begins execution on the CPU in a limited environment and hands off to subsequent stages that gain access to more resources like memory and devices. U-boot supports booting an operating system image from storage like SSD or over the network and offers features like secure boot and hypervisor support.U-Boot presentation 2013

?
U-Boot is an open source boot loader that initializes hardware and loads operating systems. It supports many CPUs and boards. The boot process involves a pre-relocation phase where U-Boot initializes hardware and copies itself to RAM, and a post-relocation phase where it finishes hardware initialization and loads the kernel or operating system. Debugging can be done before and after relocation by setting breakpoints and examining memory.U Boot or Universal Bootloader

Arm device tree and linux device driversHoucheng Lin
?
This document discusses how the Linux kernel supports different ARM boards using a common source code base. It describes how device tree is used to describe hardware in a board-agnostic way. The kernel initializes machine-specific code via the device tree and initializes drivers by matching compatible strings. This allows a single kernel binary to support multiple boards by abstracting low-level hardware details into the device tree rather than the kernel source. The document also contrasts the ARM approach to the x86 approach, where BIOS abstraction and standardized buses allow one kernel to support most x86 hardware.Embedded_Linux_Booting

?
The embedded Linux boot process involves multiple stages beginning with ROM code that initializes hardware and loads the first stage bootloader, X-Loader. The X-Loader further initializes hardware and loads the second stage bootloader, U-Boot, which performs additional initialization and loads the Linux kernel. The kernel then initializes drivers and mounts the root filesystem to launch userspace processes. Booting can occur from flash memory, an eMMC/SD card, over a network using TFTP/NFS, or locally via UART/USB depending on the boot configuration and available devices.Linux Kernel Image

The conversion of the ARM Linux kernel over to the Device Tree as the mechanism to describe the hardware has been a significant change for ARM kernel developers. Nowadays, all developers porting the Linux kernel on new ARM platforms, either new SOCs or new boards, have to work with the Device Tree. Based on practical examples, this talk intends to provide a ""getting started guide"" for newcomers in the Device Tree world: what is the Device Tree? How is it written and compiled? How do the bootloader and kernel interact? How are Device Tree bindings written and documented? What are the best practices for writing Device Trees and their bindings?

A bootloader loads an operating system after hardware tests. It begins by initializing hardware and loading the BIOS. The BIOS then loads the master boot record from the disk, which loads secondary bootloaders. These load the operating system by accessing memory in both real and protected modes. The boot process involves loading kernel files and an initial ramdisk to start processes and mount the full filesystem.What is Bootloader???

Bootloader utilizes to program microcontrollers by providing a medium of communication between them. Hence small bootloader uses to make controller programmable very often as like Arduino series board. Microcontrollers like 8051, PIC without bootloader requires the external programmer to burn the program inside the memory of the microcontroller. In addition to it requires preciously control output states of various pin mode which should be in sequence according to the datasheet of the manufacturer. Here this PPT has portrayed as an example of idle configurations that requires to run the bootloader and what happens if the bootloader is installed inside the memory of the controller.Scalable Matrix Multiplication for the 16 Core Epiphany Co-Processor

Linux uses /proc/iomem as a "Rosetta Stone" to establish relationships between software and hardware. /proc/iomem maps physical memory addresses to devices, similar to how the Rosetta Stone helped map Egyptian hieroglyphs to Greek and decode ancient Egyptian texts. This virtual file allows the kernel to interface with devices by providing address translations between physical and virtual memory spaces.Kdump and the kernel crash dump analysis
Kdump and the kernel crash dump analysisBuland Singh
?
Kdump is a kernel crash dumping mechanism that uses kexec to load a separate crash kernel to capture a kernel memory dump (vmcore file) when the primary kernel crashes. It can be configured to dump the vmcore file to local storage or over the network. Testing involves triggering a kernel panic using SysRq keys which causes the crash kernel to load and dump diagnostic information to the configured target path for analysis.Introduction and course Details of Embedded Linux Platform Developer Training

Java Apps on AWS Without the Headaches: Fast Builds, Cheap Deploys, No Kubernetes
Let¨s face it: the cloud has gotten out of hand. What used to be simple！deploying your Java app！has become a maze of slow builds, tedious deploys, and eye-watering AWS bills. But here¨s the thing: it doesn¨t have to be this way. Every minute you spend waiting on builds or wrestling with unnecessary cloud complexity is a minute you¨re not building the features your customers actually care about.
In this talk, I¨ll show you how to go from a shiny new Java app to production in under 10 minutes！with fast builds, cheap deploys, and zero downtime. We¨ll go deep into optimizing builds with Gradle (it¨s time to leave Maven in the dust), parallelization strategies, and smarter caching mechanics that make your CI/CD pipelines fly. From there, we¨ll review the dozen+ ways AWS lets you deploy apps and cut through the chaos to find the solutions that work best for lean, fast, cost-effective pipelines. Spoiler: ECS and EKS usually aren¨t the answer. Oh, and I¨ll even show you how AI tools like AWS Bedrock can help streamline your processes further, so you can automate what should already be automatic.
This talk is for developers fed up with the cost, complexity, and friction of modern cloud setups！or those who long for the simplicity of the Heroku/Beanstalk/PCF days when deploying to the cloud wasn¨t a headache. Whether you¨re on AWS, Azure, or GCP, you¨ll learn actionable, cloud-agnostic tips to build faster, deploy cheaper, and refocus on what matters most: delivering value to your users.
