I am trying to update firmware in FRDM K64F board. When I update it to 0226_k20dx128_k64f_0x5000.bin, it works fine. But it seems like not a latest one. When I update it to k20dx128_k64f_if_mbed.bin, board stops working. no any led, no mbed drive, when I press reset button then it goes back to boot loader mode. If I put back 0226_xxx then it starts working again.
any help will highly be appreciated!
