Name : Research: Porting Linux to Ultra-Low Power Microcontroller
Objective : This working group’s objective is to explore the available RTOSes as well as developing a linux port from scratch for the Ambiq Apollo 3 & 4 series processors or similar ultra low power microcontroller. The research from this group will support future/current working groups.
Timeline : 4/14/21-5/13/21

"All skills are welcomed! We are also looking for folks who have:
- Experience with:
- Embedded Development
- Electrical Engineering
- Software Developers
And as @xorlof describes his PaperTerm project:
“At this point, we need other people interested in the idea of this super-low-power device with its “I’m not a regular laptop” aspiration. You can help us figure out the key important areas for us to focus on. No special skills needed! If you like the sound of such a device, email us and join! No required time-commitment and no contribution is too small and no worries of all of this microcontroller-type talk goes over your head. We need you!”
This project will operate alongside the PaperTerm project, of which I am also a member of (and encourage you to check out!). While the PaperTerm is focused on developing the requirements for a lightweight client used for interacting with programs on remote computers (such as SSH/telnet,remote desktop & VNC), this RTOS/linux port will be geared towards determining the system requirements that would be needed to run (initially smaller) apps stored on flash/SRAM of the local microcontroller. That is, determining what the firmware/bootloader, kernel and app size should be in order for the system to be feasible & developed.
Kernel basic intro (Start here): https://tldp.org/LDP/tlk/tlk-toc.html (definitely more accessible than the following advanced kernel/linux OS tutorials)
The results of this project can then be applied to the PaperTerm project and also Drivers for E-ink Displays research group at a later time towards an e-ink laptop using a microcontroller having both low-power and high-power modes (or just one if you prefer! ).
