Hi,
I have the FRDM-KL25Z & KITPF3000FRDMPGM board and I use KL25Z USB(not the openSDA) to program PF3000(MC32PF3000A0EP).
But now it can't work. I think it is firmware wrong with the FRDM-KL25Z board.
I buy a new kit of FRDM-KL25Z & KITPF3000FRDMPGM board again, but they can't work too.
when I try to connect the board to the computer, the computer does not seem to detect the board as it does in the openSDA usb conector.
Is it a problem of the KL25Z USB connector?
how can I make my computer detect and recognize the board?
I can connect to the board using the PnE micro Multilink debugger if it can help.
I can see a USB-UART device at device manager, but it can't change to USB-HID device.
If it can found, can see HID-compliant device at device manager, and if launch PF3000_HID_GUI, can see Vendor ID&Part ID.
Vendor ID:0x15A2,Part ID:0x00F7
But it can't find HID-compliant device at device manager.
How can I do for FRDM-KL25Z to make KL25Z USB to program PF3000?
Thanks in advance,

Max
