Linux Firmware Update

[linuxFTW]

In order to update the firmware of the Concept2 devices you need to install the official Update Utility which is not available for Linux. The official utility only grabs the firmware files and puts them in a folder. You don't need a utility for that if you are willing to update via USB stick. I found out how to get the official firmware so that you fellow Linux users can update your machines too
You can find it here: https://github.com/pentamassiv/Concept2LinuxUpdater

Thanks for sharing. Be aware: in your script the versions are hardcoded (and outdated).
It is safest to do what the Concept2 Utility does: get a list of most recent firmwares, and then get each of those.
See below for the script I use (it requires curl, jq, 7z)

Note: I have not included the token that is needed to get the list of files from the Concept2 site.
To get that one, here's a hint: use e.g. https://mitmproxy.org/ and run Concept2 Utility.

Code: Select all

#!/bin/bash

UNZIP="/usr/local/bin/7z"
JQ="/usr/local/bin/jq"

DESTINATION=$HOME/Downloads/Concept2/Firmware

mkdir -p $DESTINATION
cd $DESTINATION

#TOKEN="Authorization: Basic ..." # <<< you will have to figure out how to get that token
FILES=$(curl -s "https://tech.concept2.com/api/firmware/latest" -H "$TOKEN" | $JQ -r '.data[] | select(.status == "public") | .files[0].name' | paste -s -d, -)

curl -s -O "https://firmware.concept2.com/files/{$FILES}"

$UNZIP e -y "*.7z" > /dev/null

BTW if you prefer to use your hardcoded list of (outdated) files, here is the more compact version:

Code: Select all

FILES="pm3_euro_R108B000.7z, pm3a_eurochinese_R332B000.7z, pm3aski_eurochinese_R732B000.7z, pm4_eurochinese_R029B000.7z, pm4a_eurochinese_R332B000.7z, pm4aski_eurochinese_R732B000.7z, pm5_eurochinesebin_pub_secure_R032B000.7z, pm5_zhjakobin_pub_secure_R032B000.7z, pm5ski_eurochinesebin_pub_secure_R732B000.7z, pm5ski_zhjakobin_pub_secure_R732B000.7z, pm5v2_eurochinesebin_pub_secure_R171B000.7z, pm5v2_zhjakobin_pub_secure_R171B000.7z, pm5v2bk_eurochinesebin_pub_secure_R329B000.7z, pm5v2bk_zhjakobin_pub_secure_R329B000.7z, pm5v2ski_eurochinesebin_pub_secure_R871B000.7z, pm5v2ski_zhjakobin_pub_secure_R871B000.7z"

curl -O "https://firmware.concept2.com/files/{$FILES}"

and for fun, here's a way to display the summary as a table:

Code: Select all

#!/bin/bash

#TOKEN="Authorization: Basic ..." # <<< you will have to figure out how to get that token
curl -s "https://tech.concept2.com/api/firmware/latest" -H "$TOKEN" | jq -r '.data[] | [.status, .machine, .release_date, .short_description, .files[0].name] | @tsv'

Code: Select all

Thank you for the feedback. That was great!

I did not know about mitmproxy. I gave it a try and used it to extract the token. Worked like a charm. I then stored the token as a secret on Github and created an Action that is scheduled to run once a day and use the "secret" token to check for new firmwares. If there is a new firmware available, the Action will automatically update the hardcoded links of the script. This way the token is not published on the repo, but users still get all updates as soon as they become available (and they pull the new script).
This should be much better now than my previous version. Feel free to make more suggestions. If you'd like to be credited somehow, let me know how you'd like me to do that

[wivku]

Nice. In that case: instead of using Actions to generate new update.sh script you could consider saving the list of files in e.g. files.json
And let the update script point to the Github location (and as a fallback the local -possibly outdated- local version of that JSON file).

Code: Select all

FILES=$(curl -f -s https://raw.githubusercontent.com/pentamassiv/Concept2LinuxUpdater/main/files.json || cat files.json)

This way the client does not have to do a git pull to get updated firmware files before running update.sh.
(note regarding the readme: for git pull the repo location is not needed if you are in the repo directory)

[wivku]

BTW I have expanded + published the script I originally wrote for myself:
https://github.com/wivaku/getConcept2Firmwares

Intended for people that don't mind figuring out the authorization token themselves.
Feel free to copy/paste from that one if you like, no credit is needed.

Features:
- parameter: download public or (only) beta firmwares
- parameter: destination (e.g. directly to the USB stick)
- parameter: which monitor to use (default: pm5, which is actually the only useful one)
- deletes old files in the destination (similar to how Concept2 Utility works)
- firmwares intended for internal use are excluded

You absolutely can use wine. You do not need a windows virtualbox.
This is pretty simple for your average linux user.

Partition a 16GB flash drive with FAT32. Use the partition manager in your OS is the easiest way, or you can use fdisk and mkfs.

Once you have an MBR FAT32 (ID is 0b in fdisk) , following the instructions, plug that into your rower first.

It will "initialize" the drive -- you will enter a username on the screen to name your 'logbook', and it will create a directory structure on the drive:

Concept2>
DiagLog
Firmware
Logbook
Special
Getting Started.html

Now, run the Concept 2 Utility exe downloaded from the website using wine.

> wine <name of concept2 executable>

Click update firmware, choose your PM version, and then plug in the rower initialized drive, and mount the drive to the OS. Once the utility sees a new drive mounted, it will look for the above structure on it. If you did not initialize with the rower, it will claim you formatted the drive incorrectly.

Once you insert initialized usb drive you can click download firmware, and itll grab the latest set. It will report back "Files installed!" and you can go plug this back into the rower.

I used a Fedora based distro with wine-9.7 (Staging)

Hope this helps.

Years ago the windows utility was the only way to load firmware. So linux users needed a solution like the ones in this thread.

Now that ergdata updates PM5 firmware over bluetooth Linux users with a phone/table that can run ergdata should be all set without needing windows, wine or the Concept 2 Utility.

@c488 - super clear description of how to load pm firmware using a usb drive, linux and wine. nice.
