Setting Up Raspberry Pi in Headless Mode 6/18/2023

 

This post is part of a series of notes I originally recorded on a GitLab wiki for our QuitetThing project with can be found here:

We are going to use Raspberry Pi's as the initial development platform for the Audio Bonnet that will help perform the Active Noise Cancellation.

We are going to be communicating with the Pi's using SSH and maybe a virtual desktop application down the road.

To get the Pi to work in what they call "Headless Mode" you have two main options. If you have the ability to operate the Pi as a standalone computer, you can log in and make sure it is connected to the internet (you can also use Ethernet) and you need to make sure ssh is enabled.

If you do not have the ability to plug the Pi into its own monitor or you are starting/willing to start from scratch follow the instructions at this link: https://www.tomshardware.com/reviews/raspberry-pi-headless-setup-how-to,6028.html

The easiest method is the one titled "Installing Raspberry Pi OS on Your microSD card". The only difference from the steps is that you need to select the 64-bit version of Raspberry Pi OS if you are using a Raspberry Pi 4. This is because at the time of this writing (20230718) this is a bug that does not allow the Adafruit install scripts for the Audio Bonnet to run correctly on a fully updated Raspberry Pi 4 running the 32-bit version. See this link for a more in-depth reason why this is necessary: https://forums.adafruit.com/viewtopic.php?t=200461

Once the Pi is up and running you can use a program called Nutty to scan either your wifi network or your ethernet port(s) to find the IP address of the Pi you would like to connect to.

To connect to the Pi over SSH use the follwing command:

ssh [username]@[ip address of Pi]

Enter Yes if it asks you if want to add the device to the known hosts and then it will ask for the Pi's password. If you didnt change anything in the setup, the default username is "pi" and the default password is "raspberry".

Used the above headless setup article to setup VNC on the pi to be able to see the desktop from my laptop. The steps use windows but I downloaded for Fedora. I got it all setup, I used the IP address of the Pi to connect to it. It was very slow and the resolution wasnt the best. I may look into better solutions or just stick to using the terminal.

EOS-S3 Thing+ Debug Setup 8/27/2023

We can now pause and resume a program running on the Thing+ in VS Code using GDB, Black Magic, and Cortex Debug. I found the template for the Black Magic config here: https://github.com/Marus/cortex-debug/wiki/Black-Magic-Probe-Specific-Configuration I modified it to fit out situation and uploaded it to the repo. To setup, you need to not have the jumpers on the Thing+ and open Black Magic in a terminal. Then select BMP Debug from the dropdown debug menu in VS Code and then press F5 to start the debug session. If it doesnt connect or attach, try to connect to the Thing+ outside of VS Code with Blackmagic and GDB. You may need to unplug the Thing+ or I found putting it into program (green flashing) mode and then connecting to in from GDB in the Terminal helped and I was then able to connect through VS Code. To set breakpoints, you can click on a line of a file that is part of the same project and folder structure as the elf you are running on the board. I wasnt able to set a brea...

Escape to the Northern Lights

Northern Lights Have you ever wanted to see the Northern Lights in its full glory? My friends and I decided to journey to Iceland in November and it's the event I am most looking forward to this year. We have been planning this trip since early 2023 and as we get closer, it's becoming more real. I've seen the Northern Lights in movies and pictures, but I can only imagine how breathtaking it will be in person. This phenomenon makes me think of a doorway to a different universe. For someone who grew up on science fiction, this experience will be like a fantasy realized. Travel Planning I am also looking forward to the country itself and traveling with friends I don't see very often. Exploring new places and trying new cuisines are two of my favorite things, and doing both with friends is just the icing on the cake. We plan to see the whole island in about 12 days, driving along the perimeter and stopping at various sights along the way. We are preparing for this trip b...

EOS-S3 Thing+ Debug Setup 8/20/2023

There is an extension for VS Code called Cortex-Debug, using the below links I have made a first pass at developing an OpenOCD launch.json file for debugging the Thing+. Cortex Debug requires gdb version 9 or above, but the version that comes with qorc is 8.x. I downloaded version 10.x from the arm link down below. I tried the most recent version ( 12.x at the time of this writing) but it had some python error that is describe in the stackoverflow link. Cortex Debug also needs a SVD file which QuickLogic doesnt provide, but there is one someone made at the eos-s3-rs repo. It is not fully featured but is a great start. https://lonesometraveler.github.io/2020/03/27/debug.html https://www.digikey.com/en/maker/projects/raspberry-pi-pico-and-rp2040-cc-part-2-debugging-with-vs-code/470abc7efb07432b82c95f6f67f184c0 https://github.com/Josfemova/eos-s3-rs https://developer.arm.com/downloads/-/gnu-rm https://stackoverflow.com/questions/72187185/arm-none-eabi-gdb-cannot-start-because-of-some-pyt...
