This document discusses character drivers in Linux. It covers the basics of character drivers including what they represent ("character" refers to devices that transfer data as a stream of bytes), major and minor numbers which identify devices, registering and unregistering drivers, implementing file operations like read and write, and using the Linux device model to dynamically create and manage devices with udev. The document provides code examples and explains key concepts like the file structures and I/O control interfaces that device drivers use to interface with the kernel and userspace.
The U-Boot is an "Universal Bootloader" ("Das U-Boot") is a monitor program that is under GPL. This production quality boot-loader is used as default boot loader by several board vendors. It is easily portable and easy to port and to debug by supporting PPC, ARM, MIPS, x86,m68k, NIOS, Microblaze architectures. Here is a presentation that introduces U-Boot.
This course gets you started with writing device drivers in Linux by providing real time hardware exposure. Equip you with real-time tools, debugging techniques and industry usage in a hands-on manner. Dedicated hardware by Emertxe's device driver learning kit. Special focus on character and USB device drivers.
U-Boot, a boot loader for Embedded boards based on PowerPC, ARM, MIPS and several other processors, which can be installed in a boot ROM and used to initialize and test the hardware or to download and run application
code.
Linux has become integral part of Embedded systems. This three part presentation gives deeper perspective of Linux from system programming perspective. Stating with basics of Linux it goes on till advanced aspects like thread and IPC programming.

Often called as the Swiss Army Knife of Embedded Linux, BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. It is written with size-optimization
and limited resources in mind. Here is a presentation that details about BusyBox.

Part 02 Linux Kernel Module ProgrammingTushar B Kute
Presentation on "Linux Kernel Module Programming".
Presented at Army Institute of Technology, Pune for FDP on "Basics of Linux Kernel Programming". by Tushar B Kute (http://tusharkute.com).
This presentation briefs about the Linux Kernel Module and Character Device Driver. This also contains sample code snippets. Also briefs about character driver registration and access.
Linux has emerged as a number one choice for developing OS based Embedded Systems. Open Source development model, Customizability, Portability, Tool chain availability are some reasons for this success. This course gives a practical perspective of customizing, building and bringing up Linux Kernel on an ARM based target hardware. It combines various previous modules you have learned, by combing Linux administration, Hardware knowledge, Linux as OS, C/Computer programming areas. After bringing up Linux, you can port any of the existing applications into the target hardware.
The slides begins with introduction to the character drivers and then mentions the various APIs for registering the character driver. Dynamically creating the device file and IOCTL

★ Session Summary ★
SWG is porting OP-TEE to ARMv8 using Fixed Virtual Platform. Initially OP-TEE is running secure world in aarch32 mode, but with the normal world code running in aarch64 mode. Since ARMv8 uses ARM Trusted Firmware we have patched it with an OP-TEE dispatcher to be able to communicate between secure and normal world.

How to create your own Linux distribution (embedded-gothenburg)Dimitrios Platis
= Please note that the code in the slides may not be working
= Refer to the repository for working examples: https://github.com/platisd/meta-dimitriOS
Welcome to a beginner-friendly deep dive on how to create your own Linux distribution!
But why would you want to create one yourself?
** BACKGROUND **
Mainstream Linux distributions (e.g. Ubuntu, ArchLinux) enable their users to perform a plethora of tasks and often include the means for further customization of the system via a package manager, development tools, a desktop environment etc.
However, if you are creating a device that has a very specific set of use cases and needs to operate under strict constraints in regards to resources, power consumption, performance, or robustness, then using a full-fledged desktop operating system is infeasible. This is very common when developing embedded systems, meant to be used in an IoT application, the automotive or telecom industry, and so forth.
To create an Embedded Linux operating system, there are two paths you can follow:
1. Create a "golden image"; often the first choice when prototyping with a development board, e.g. a Raspberry Pi.
An off-the-shelf operating system, such as Debian, is hacked until it fits the purpose. Then clones of that "golden image" are created and installed in more devices.
This is good enough for creating a proof-of-concept but quickly falls short when the project becomes more complicated, larger, or the need to develop product variants arises.
2. Create a configuration-based distribution; the industry-proven way to create an Embedded Linux operating system.
Instead of maintaining the operating system as a big binary, its components are specified in version controllable configuration files. Setting everything up may require a steeper learning curve since things are not already conveniently in place. However, it is the only sustainable way to go forward when it comes to serious Embedded Linux development.
More on the topic: https://www.linuxjournal.com/content/linux-iot-development-adjusting-binary-os-yocto-project-workflow
** WORKSHOP **
In this workshop, we are going to demonstrate the "ingredients" needed to build your own Linux distribution using the Yocto project. Then we will run our distribution on a Raspberry Pi board.
Yocto is a collection of tools and processes enabling the creation of configurable Embedded Linux distributions. You define which components are to be included in your operating system with software- and hardware-specific configuration files. "Recipes" determine how these components are built and also what they depend upon. Finally, these recipes are utilized by "bitbake" (a tool offered by Yocto) to build your custom Linux image.
During the workshop, we will go over the setup needed to create a custom operating system for a typical IoT device. It boots up, automatically connects to the internet, and launches a C++ demon that fetches information from a cloud API.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.
