Topic:Snap your application for embedded system
1) Snap and Ubuntu Store for IoT
2) Snap vs Docker
3) Snap your app demo
Speaker 2: StarNight
Topic: A journey to boot Linux on Raspberry Pi
Outline:
I will share several possible boot process of Linux distribution on Raspberry Pi, and the boot process of a Linux distribution with OSTree technology. Take Endless OS booting on Raspberry Pi as an example.

題目:A journey to boot Linux on Raspberry Pi
大綱:本次將分享幾個 Linux distribution 在 Raspberry Pi 的可能開機過程,以及自己實做一個搭配 OSTree 技術的 Linux distribution 的開機流程。以 Endless OS 在 Raspberry Pi 上開機為例。
透過觀察幾個 Linux distribution 的開機過程,發現 U-Boot 可以做到將開機過程分為「高度硬體相關」與「一般系統皆可通用」的兩大步驟。特別是「一般系統皆可通用」的開機步驟,滿足搭配 OSTree 技術的系統(包含,但不限於)有方便、一致的開機模式需求。更進一步,有機會解決各硬體專屬 Device Tree 的佈署問題。
這次將分享如何實做讓系統在 Raspberry Pi 上開機的過程!
