The interface firmware FAILED to reset/halt the target MCU on FRDM-K64F.
I'm using a FRDM-K64F and I uploaded the MBED firmware (0226_k20dx128_k64f_0x5000.bin) and next the example helloworld_k64f.bin to the board, but nothing happens and I get a txt file called FAIL and it says "The interface firmware FAILED to reset/halt the target MCU", also the chip heats up. I've tried with other firmwares and I get similar issues, doesn't matter which firmaware I upload, I get the file "FAIL.txt". So I don't know if there's a way to solve this.
