Anyone knows or can shade me some lights on the KE02Z Freedom Board 3.3V OpenSDA debugger's support for 5VDC - Can it works perfectly well on an external 5VDC powered KE02 device target board?
Up to current version, you cannot input 5V directly to FRDM board. Because K20 is 3V chip. In future version, we will modify this issue. But for your KE02 application, you can power KE02 with 5V.
