Kinetis Bootloader 2.0 MSD Drag and Drop

[guitardenver]

I have the latest Kinetis bootloader 2.0 demo working on a freedom K22 dev board. I upload the freedom_bootloader to the dev board and use the Kinetis Flash Tool PC App with the USB/HID option to load the led_demo. This works great.

The freedom_bootloader also enumerates as a MSD device. There is a couple info and log files in the drive.

The Question:

Does the MSD on the freedom_bootloader support drag and drop firmware updates? I put the led_demo.bin or screc or hex file in the drive and nothing happens?

I'm running win 7.

Hi Matt,
I just use the FRDM-K22 to replicate your issue, however it works well on the Win 7.

So I'd like to suggest that you can update the OpenSDA firmware through the link as below, then try again.

jeremyzhou,

The OpenSDA MSD bootloader works fine. I can program the target MCU with the dev board. I used the OpenSDA to program the Kinetis bootloader 2.0 onto the target MCU (MK22 MCU). The MSD drag and drop is for the 2.0 bootloader not the mbed OpenSDA bootloader.

This is the bootloader:

Kinetis Bootloader|NXP

I have the USB plugged into the "USBK22" port not the "SDAUSB" port.

Hi Matt,

Thanks for your reply.

Sorry, I misunderstand your question, the USB-MSC hasn't supported the BIN or SREC file now, except the SB file.
