Hi
>>how to download bootloader file. there no option to download file.
Do you mean how to download it from the web site? If this is what you mean you just click on the file link high-lighted in yellow:
There is also a verson for loading via Ethernet (from any web browser) called uTaskerSerialBoot_FRDM-K64F_KBOOT_HID_UART_MSD_WebServer.bin (rather than with SD card loading).

hello soledad,
thank you. but my question was simple.is every time we want to press reset switch to execute code?

Yes, if you are using the MSD bootloader, you have to press the reset button to start the application.
If you do not want to press the reset button, I recommend that you do not use the MSD bootloader, but use the debugger instead. As from Eclipse/Kinetis Design Studio, you can press one button to download and run the application, see Emulating Eclipse ‘Run’ with ‘Debug’ Configuration | MCU on Eclipse
Otherwise, use the gdb in command line mode and use the gdb 'detach' command: this will disconnect from the downloaded application and start it.
I hope this helps,
Erich
Hi
If you install a boot loader from µTasker Kinetis FRDM-K64F support (also allows USB-MSD loading) then the new code will start without needing to press the reset button.
