Total hack, but this just worked. We still need a clean way of uninstalling opencv2.4 $ opkg list | grep opencv $ opkg remove lib32-opencv --force-removal-of-dependent-packages $ opkg list | grep opencv $ opkg remove lib32-opencv-dbg --force-removal-of-dependent-packages $ opkg remove lib32-opencv-calib3d2.4 --force-removal-of-dependent-packages $ opkg list | grep opencv $ opkg remove lib32-libopencv-calib3d2.4 --force-removal-of-dependent-packages $ opkg list | grep opencv $ opkg remove lib32-libopencv-core2.4 --force-removal-of-dependent-packages $ opkg install opencv_3.4.6_8x96.ipk $ /usr/bin/opencv_version 3.4.6

We've posted a git-perltools package that should provide a workaround for this issue if you install on the either the emulator image or the target. Note at this time, when using on the emulator, you'll need to run it again after exiting... Download the git-pertools package from here: https://docs.modalai.com/docs/resources/downloads/#additional-packages Copy to the emulator (place in directory where you run the emulator from) or target (using adb push) Install using `opkg install lib32-git-perltools_2.5.0-r0_armv7a-vfp-neon.ipk' (note: some opkg warnings will display but can be ignored) You should be able to use the submodule command after this. Please let us know if you have any problems.
