I don't have time to go into details, but usually the best way to send data between MCUs is via their UART or SPI interfaces. UART is usually easier. SPI is usually faster.
Take a look at the UART and SPI pins for your MCUs and what software is available.
I have a beagle board and silicon labs efm32. i want to send data iam receiving from efm 32 to my bbb and display it on my computer. iam not able to figure out how to code bb to make efm32 to send data to it.

It is up to you to select an interface. johnbeetem has provided some popular examples.
Once you have decided on an interface, you can google for code examples for that interface and for your desired programming language.
Because these interfaces are standard, you can be assured that your two boards will communicate. As a result, you don't need to search for
a "beagle board to EFM32" solution. You just need to search for "beagle board X interface" example software, and "EFM32 X interface" example
code where X is the interface you have chosen.
If you're unfamiliar with the interfaces mentioned, then you really need to read up on them (wikipedia at a minimum) because they are fundamental for device interfacing.
