Hello, my name is Pavel, and I will be supporting your case, so I am reviewing your case, but I understand the next if I do not right, please let me know.
There are 2 forms to get the .bin from the IDE, the first is explained on the next page MCUXpresso IDE: S-Record, Intel Hex and Binary Files | MCU on Eclipse.
The final form is the easiest when you build your project appears a Debug file there in the .axf file click right>Binary Utilities>Create binary.

Let me know if you have more questions.
Best regards,
Pavel
