FRDM K64

Hello,

maybe someone can help.

I try to program the K64 and start with "blinky" and so on... after some succesful tries with a i2c LCD I have following problems....

When I plug in my K64 board in an USB- port a former written program (a modified blinky) is running..... when I press the reset- button, the Windows- Explorer shows me BOOTLOADER(E:)

So far, so god!

Now, when I copy a new program, the copying will be indicated, but after this.... drive E: is no longer in the Windows- Explorer and the small LED near the Ethernet Plug is blinking fast..... no new program on the board....

Some ideas?

Hi, Can you provide a bit more info about the failure? If you are you able to return to the bootloader mode, can you please open up the mbed.htm file in the BOOTLOADER directory using a text editor and report the Version number? I'd recommend following the firmware update instructions to update to the latest firmware and then try programming the application binary by mounting the MBED directory. https://developer.mbed.org/platforms/FRDM-K64F/#firmware-update

Thanks a lot for the information! I have the software (on board) updated and the driver for usb (mbedWinSerial) and now it's working fine! Thank You..... I'm afraid, I will found enough other problems..... later....
