I have started on the path of working with the QuickFeather board from SparkFun. There are some gotcha’s I was able to solve along the way that might baffle some people. My solutions may not be ideal, but here they are.<\/p>\n\n\n\n
I found that reading the quickstart guide was very good. (Especially around the area of setting up the access to the \/dev\/ttyACM port(s) (go to Linux Note for Serial Ports on the page https:\/\/qorc-sdk.readthedocs.io\/en\/latest\/qorc-setup\/quickstart.html#quickstart-with-qorc-sdk<\/a> )<\/p>\n\n\n\n Note: the following instructions are based on using Ubuntu as your OS.<\/p>\n\n\n\n The following is correct. I did it from my home directory:<\/p>\n\n\n\n Next is the part which is not totally correct if you are following the instructions. Read on. <\/p>\n\n\n\n The instructions say that you must have python3<\/em> installed as well as pip<\/em>. That is correct. Do that. I am assuming you know how to do that on your platform, the instructions for both of those are on the web and are correct. <\/p>\n\n\n\n One more install is required but not mentioned: You must first install curl<\/em>. <\/p>\n\n\n\n Finally, you *must* run the install as root. Otherwise the Symbiflow install fails (and who knows what else?). However, since the envsetup.sh must be run using ‘source’ you cannot just use sudo. Instead, do the following:<\/p>\n\n\n\n With the above instructions, the install will run to the end and install correctly. Run the chown command as root to put the ownership of the installed files (which were just created and owned by root) to you, so you can run and modify items as needed.<\/p>\n\n\n\n Next, if you wish to always have the development environment available as soon as you log in, you need to edit the file “.bashrc” in your home directory and add the following line last in the file, assuming qorc-sdk is in your home directory:<\/p>\n\n\n\n That line tells bash to call the setup script for the Quickfeather board at login. It will add (base) to the beginning of your bash prompt in your terminal. Otherwise, just run that command from terminal just before beginning work on the Quickfeather board.<\/p>\n\n\n\n I followed the instructions on this video (near the end of the video) to start the recovery process: https:\/\/www.youtube.com\/watch?v=Q5GIZUsXb3I<\/a><\/p>\n\n\n\n In my case, I also needed to download some binaries, as the bootloader binary provided in the quickfeather-dev-board repository did not work, and it bricked my board, from the point of view of uploading new applications. Use qf-initial-bins instead. see “Successful.
