I thank you for trying to help me . But it happens that I need to "produce" my program within the Kinetis platform , and while I'm having some problems in the read-write flash memory , where I desire to work . If possible I would like to help me in the sequence of steps required to perform the entire procedure , from start to execution. Because I need that my program itself off when you receive a new "package" via ethernet .

Thanks for the material, will help me a lot . However still need an example to write to flash memory within the codes in Kinetis.Este can be performed by any MCU , preferably K64F FRDM . For now I'm focused on the recording of flash memory, but it shows some errors when I try to use the functions. If possible, I would like to send me a sample code that actually handles the flash memory.

Hi

I would recommend customer to refer FNET Embedded TCP/IP Stack software, which provides Ethernet bootloader for K64 chip.


Wish it helps.

Hi Danilo

See http://www.utasker.com/kinetis/FRDM-K64F.html and the software
"Serial Boot Loader with Ethernet Web Server, USB-MSD, KBOOT-USB-HID, UART SREC"
This includes Ethernet loading for the K64 and a kit to do any custom types if needed.

Regards

Mark
