Hi Balaji,
The Software Clinic event offered a 20% discount (mentioned here) but no free boards were offered. This specific event focused on i.MXRT1050 and i.MXRT1060 crossover processors.
See below the current supported platforms and enablement. As you can see, Arm NN (v19.05) is fully integrated into Yocto recipe supporting i.MX 8 Series (eIQ officially supports the NXP i.MX 8 Series but it is possible to build eIQ for i.MX 6 and i.MX 7 Series).

Please refer to eIQ Software Fact Sheet and NXP eIQ Machine Learning Enablement for details about supported platforms, features and software available with NXP eIQ.
Regards,
JC
