This is regarding FRDM-K22F development board failures. I've two FRDM boards gone faulty after flashing Firmware into it (different FWs). 

Issue Details: First board was purchased sometime in 2015 and had been working till couple of weeks back without any issue. Second board we purchased in 2016 March. Both boards failed in similar fashion, after FW (not FW issue, have flashed the same FW before and flashed different FWs in First, second boards ) flashing the reset LED is glowing and  board is not responding to Reset Switch. Open SDA interface is coming up as Mass Storage Drive, but not able to Flash firmware. Please provide your feedback ASAP.
