Firmware Build Fails After Build For Nicla Vision

OpenMV Products
1

The firmware successfully built for TARGET= OPENMV_RT1060 using:
make -j$(nproc) -C src/micropython/mpy-cross -B
make -j$(nproc) TARGET=OPENMV_RT1060 -C src

I then tried to build the same firmware for TARGET=ARDUINO_NICLA_VISION and got this error messages.

I thought it might be because of the size of the .tflite file I had added to /models (91kb), so I removed that file from /models and rebuilt for ARDUINO_NICLA_VISION, but still got same error message.

Now when I try to build for TARGET= OPENMV_RT1060, I get all sorts of error messages. Tried using -B to force rebuild for both make cmds and still got build errors.

Hi, you only need to build mpy-cross once.

cd src/micropython/mp-cross
make clean
make

After that you don’t need to do it again unless there’s a major micropython update. For building the firmware always clean first when switching boards.

cd src
make clean
make TARGET=OPENMV_RT1060 -j8

And when building the firmware over and over again just:

make TARGET=OPENMV_RT1060 -j8

make -B just forces a build of all targets. This isn’t the right usage.

Thanks, that worked :slight_smile:
