The `MultiBlink example fails to compile against CC3200 EMT, but succeeds agains MSP432 EMT.

1. BLUE_LED is unknown, should be replaced by YELLOW_LED

Add

#define BLUE_LED YELLOW_LED

2. Linking fails, with the following error message

Adding empty setup() and loop() to the MultiBlink.ino file solved the case.

void setup() { }

void loop() { }

It looks like the task parser doesn't behave the same way against the CC3200 and the MSP432.

This issue was caused by the package provided by the link for the beta, which pointed to the wrong package, actually the CC3200 standard boards.

This issue is solved with the right cc3200emt-core package.

This issue can be closed now. I don't have the credentials on this repository for closing it myself. Thank you.
