Run-time Update

eIQ Neutron-S targets

Neutron Runtime Components

The neutron runtime for the eIQ Neutron-S targets (e.g. iMX95, iMX943) consists of the following files:

• Neutron firmware: NeutronFirmware.elf

• Neutron driver: libNeutronDriver.so

• TensorFlow neutron delegate: libneutron_delegate.so

Updating the Neutron Runtime

To update the neutron runtime on a target device, upload the files to their designated directories, as follows:

File	Target Directory
NeutronFirmware.elf	/lib/firmware/
libNeutronDriver.so	/lib/
libneutron_delegate.so	/lib/

Important

Please back up the existing files on the target before updating!

eIQ Neutron-C targets

Neutron Runtime Components

• The neutron runtime headers and libraries for the eIQ Neutron targets (e.g. iMXRT700) consists of the following files:

  • Neutron errors C header: NeutronErrors.h

  • Neutron driver C header: NeutronDriver.h

  • Neutron firmware library: libNeutronFirmware.a

  • Neutron driver library: libNeutronDriver.a
