There is a new fresh release of both the firmware and the python library and client! The last release (2022.01) was from 2 months ago but we already added quite some extra functionality so we wanted to make a snapshot of this before continuing on other priorities.
Kbuild on CF firmware
One of the biggest changes that you will notice, is that there is now a new way to configure your Crazyflie firmware before building it. The old config.mk is gone and you will now need to either automatically generate a config file or generate one with the menuconfig, of which kbuild is most known for. For more information, please read the blogpost about this latest change, for the exception that we do prefer the users to use ‘make cf2_config’ as instructed in the 2022.03 version of the repo documentation.
Platform support for Bolt
We now defined the Bolt as a different platform. That means that for each release, there should now also be a bolt flavor zip file, next to the cf2 and tag zips, as you can see in the release page. Moreover, if you want to build the firmware to be Bolt compatible, you would first need to do ‘make bolt_defconfig’ to generate the needed configs with kbuild. For more information of how to add your own custom platform, please check out these instructions.
2+ Lighthouse base stations (experimental)
For those that feel constrained by the max 2 lighthouse base station support in the firmware and client, this functionality is now part of the release. This blogpost will explain more about this, and it is still experimental in nature, as you would need to reconfigure the firmware with… you guessed it: Kbuild! Also the geometry estimation needs to be done as a separate python script as well all from the Crazyflie python library. No worries, if you still prefer using the cfclient, it still uses the old way of estimating if you click the button, but just remember that you would need to do something extra in order to get 2+ base station support.
New VM release
We were also made aware of a pretty big error in the bitcraze VM, namely that we still used the old git:// type url for github repositories. IN the new release of the bitcraze VM this should be fixed, so please download the new one, or fix it yourself in your current VM by changing the remote URLs of the github repos you are working on to https://.
One comment on “New release 2022.03”
Thanks for the sharing, an awesome new firmware release.
I have two suggestions about the VM release.
1. It seems like the type like “git@” works better than the “https://”, as for me, it downloads the repositories faster and it’s safer, also recommended by Github official.
2. I look forward to there will be a docker container providing similar command functions to the VM, it could be shared easier and occupy less memory.
