I've plugged in my brand new FRDM-K64F.
I've installed MCUXpresso SDK, IDE, Config Tools and (windows) serial driver.
I've compiled the "hello world" demo.
But when I click on 'debug', I get:
One thing to note: I noticed the USB device "bouncing" every 20 seconds or so: it would play the audible alert for "disconnecting" and then "connecting" a USB device.
Consequently, I tried the following:
- Rebooted my Windows 10 box
- Plugged the FRDM-K64F directly into the computer's USB (not via a port expander)
- Swapped USB cables
... but none of those made a difference. (I did plug in my ancient KL25Z and it came up without any problems.)
Since all of my other USB device have been behaving, I'm suspecting a faulty FRDM-K64F. Are there any other things I can try before I return the board? And if it *is* a faulty board, what's the protocol for exchanging it? (I purchased it from DigiKey.)
