voxl-emulator is deprecated. Use voxl-cross for building VOXL applications instead.

Install the voxl-emulator Docker Image

voxl-emulator enables one to develop CPU-based applications for VOXL and VOXL Flight, then test CPU-only in an emulated environment.

The VOXL 1 emulator image (voxl-emulator_v1.7.tgz) is no longer distributed on downloads.modalai.com.

qrb5165-emulator enables one to develop CPU-based applications for VOXL 2, then test CPU-only in an emulated environment. It is an ARM 64 emulator with the VOXL 2 sysroot mounted. It has very limited application to end developers. It is for low-level service development for cross-compiling applications not yet supported by cross-compiling in voxl-cross
