Issue with tinycore + pypilot hat / Does not find IMU

[MBJ335]

Hello,

OK ; compilation executed and everything works fine by now.

Here follows the commands for compilation for the ones interested with tinypilot_2020_10_27.img.xz image:

Code:

# *** Compile last git version of RTIMULib2 ***
# Prepare directories, get last git and compress in .tar.gz (expected by python-RTIMULib.build)
cd ~
mkdir RTIMULib_update
cd RTIMULib_update
git clone git://github.com/seandepagnier/RTIMULib2.git
tar czvf RTIMULib2.tar.gz RTIMULib2
rm -rf RTIMULib2
# Extract, rename, compile and generate squashfs (to make persitent)
sudo sh /mnt/mmcblk0p2/tinypilot/pypilot_dependencies/python-RTIMULib/python-RTIMULib.build

# *** Reboot... ***
sudo reboot

The script python-RTIMULib.build execute the compilation and generation of the package necessary for the specific structure (RAM filesystem) of tinycore (tinypilot base) ; looking at the code is interesting.

Here is the extract of /var/log/pypilot/current:

ICM20948 is indeed recognized ; tests indicate that driver is operational.

Thanks Sean for the advices, time, dedication and all work ; always deeply impressed !

Best,

Xavier.

Hello Xavier,
I have the very same problem you got as i've just received a new Pypilot hat a few days ago, I understand the git clone command works only if the raspberry is connected to the internet how do i do that please?
