I have FRDM-k66F board, which I have tested successfully in past.
Today I tried to test it again in new system. I followed the steps - DAPLink
-
Downloading firmware bin file from here - https://armmbed.github.io/DAPLink//firmware/0253_k20dx_frdmk66f_0x8000.bin
-
Attaching the board keeping RESET button pressed
-
The board appears as BOOTLOADER, so followed these steps - DAPLink bootloader update | Mbed
i. sudo mount -u -w -o sync /Volumes/BOOTLOADER ;
ii. cp -X 0253_k20dx_frdmk66f_0x8000.bin /Volumes/BOOTLOADER/
- Removed board from the system and attached again
When I attach board, RED LED1 starts blinking forever.
If I try to copy led blinking program bin file, board suddenly gets ejected and displays message “Disk not Ejected Properly, Eject FRDM-K66F before disconnecting or turning it off”.
Can someone please help me with this.
Am I doing anythign wrong?
