Did you get this to work eventually? Can you describe the exact steps you are taking to load the s19?

Still not working, I just drag and drop the s19 or do copy src dest from the cmdline. Then I unplug and replug the device - the green led lights but the usb mass storage never appears.

I have bootloader 1.08 if that makes a difference.

Thanks for your help, Tom

I am also having this issue with my new board.

I use Windows 7 x64.

I can access the bootloader partition no problem, and copy the file across. I have used both drag and drop, and command line copy.

After I unplug the board then plug in again, there is no mass storage device. I check in the device manager, and cannot see it anywhere.

I also plugged into a spare Win7 32 bit PC, same issue.

Accessing the SDA info from the bootloader partition shows the application version as 0.00

If I copy the PE Micro MSD file to the bootloader, after restarting the board, the mass storage device pops up correctly (although as a KL25Z board, not mBed).

The KL25Z board will show a mass storage area on boot but this is not where you copy the files too. Instructions should read:

You will then get a BOOTLOADER area to copy the mbed s19 file to.

On windows it will now install the USB driver and then display the mbed drive.

Hi All,

There is a known issue with the upgrading if you are using a Linux or Mac computer. We are working with Freescale and PE Micro to overcome this.

As long as you are using a Windows machine, the upgrade process will run smoothly, as per the instruction in :

https://mbed.org/handbook/mbed-FRDM-KL25Z-Getting-Started.

Can you confirm if the issues you are seeing are while using a Windows machine or Mac/Linux?

Thanks, Chris

I don't know the cause of this problem, but i can solve this problem like in https://mbed.org/questions/1084/mbed-FRDM-KL25Z-cannot-be-detected-in-wi/

Hey all- I've been having this bug as well, and i think I've just solved it. I suspect this is a bug in the mbed firmware because I can either load the mbed firmware or not depending on the application (not firmware) I had installed BEFORE I tried to load the mbed firmware. I solved this by: 1. Download the FRDM-KL25Z_QSP quick start package from freescale: http://cache.freescale.com/files/32bit/software/board_support_packages/FRDM-KL25Z_QSP.zip?fpsp=1 2. Download the firmware apps from pemicro: http://www.pemicro.com/opensda/index.cfm 3. (optional) Update the bootloader by loading BOOTUPDATEAPP from the pemicro firmware apps onto the FRDM 4. Load the FRDM MSD firmware v112 from the pemicro firmware apps onto the FRDM 5. Load the pwm_led app from the freescale quick start precompiled examples 6. Load the mbed firmware

If this doesn't solve it for you, try loading a couple of the other precompiled examples from the freescale quick start package before loading the mbed firmware. I can reliably prevent my FRDM from loading the mbed firmware and re-enable loading the mbed firmware based on what app I load before trying to load the mbed firmware.

Let me know if this solved your problem! James

Hello,

Has this been resolved? I'm having issues with this on both OS X and Windos 7. Bootloader comes up fine on both platforms; however, after copying the firmware to Bootloader, MBED doesn't come up.

Please Please assist!

Thanks.
