Hello every body,

and a big thanks for your answers !

I found the source of the problem ... It was very stupid ...

On Win7, I draged/dropped the BOOTUPDATAPP.......SDA from the zip files. But i didn't UNZIP the directory ... so when i dragged /dropped then unplug, nothing happened ... So a unzip all the directory on the computer, and then i dragged /dropped and when i unplug then plug the device, it was seen like FRDMKL25Z mass device.

Thanks a lot

Lucas

Hello,

have you installed the Windows USB Drivers "PEDrivers_install.exe"?

When you unplug then plug the board, did you not see MSD "BOOTLOADR"?

If no, it is strange.

If yes, you should also drag and drop MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA.

If you have already tried all, I am sorry for not helping you.

Best regards,

Yasuhiko Koumoto.
