Beaglebone Black - Flashing the eMMC with the Latest Image

The kernel image that came with the board is usually outdated. Thus, I decided to update it to the latest image by flashing the onboard eMMc with an SD card. The process I followed is documented here.

Required Hardware

Beaglebone Black, PC running on Ubuntu (ver 20.04)

Serial to USB cable, USB type A to mini B cable, power adapter

Micro SD card and adapter

TL;DR

I've started my journey by building many Linux kernel modules and my own OS from scratch. Then I contributed to open-source projects like Google Summer of Code[^12], Htop [^1], PCP [^2], and Linux kernel [^3].

I needed to choose a Linux subsystem to focus on and to learn Linux through it. I chose the performance aspects of Linux. My experience with Htop and PCP made this decision for me.

I am passionate about performance engineering and monitoring, because it gave me the power to touch dark places in the system that nobody in other Linux subsystems could touch.

I'm interested in performance aspects of software systems and metrics collection tools such as Htop, perf and eBPF.

Generalized columns in Htop - Project Summary

This is the final report for the project I was working for Google Summer of Code 2022

Abstract

The htop utility recently acquired the ability to display multiple Tabs in its user interface. Currently these display only process information. The aim of this project is to support generalized Tabs, where information beyond processes can be displayed in columns.

Extend htop Tabs to provide a more generalized Tab and Columns concept, such that top-most resource utilization for system objects other than processes can
