I have this problem too. I've tried holding down the reset while dropping the hex file in the MBED drive and it doesn't work.

Any real solutions? I haven't been able to find anything official.

I do the same what @Andrea Corrado and my FRDM KL25Z works fine again

Does anybody have solved the problem? I have the same thing with a freescale FRDM-K64F.

i too _{how can i copy the file ... the memory size only 20 kbyte ???}

9 years, 9 months ago.

Was there ever a solution to this problem? Granted I am new to the nucleo and mbed, but there seems to be a problem with either the drivers or these boards.

My nucleo worked great, was sending and receiving text over USB-serial, then it stopped. I got a copy error where the device was showing full. On an XP machine, I get that error, eject the device, then the device shows up again and it looks fine. I can copy to it, etc. but the serial USB no longer works. I can tell the board is running my code as the downstream device is initialized correctly.

What gives? Are the Nucleo boards worth the effort? I am moving from Arduino for higher performance and can't live with this, especially as I don't see anyone chiming in on the threads.

Thanks for reading at least!

I am surprise no one has posted a solution to this issue

I have the same problem and no bin file seems to work. I followed the procedures described by others and yet the issue remains "fail: SW ERROR"

6 years, 4 months ago.

Solution : i tried this solution ans its work: launch the editor, use <Windows>+<R>, then type

gpedit.msc

and after go to

Computer Configuration \ Administrative Templates \ Windows Components \ Search \ Do not allow locations on removable drives to be added to libraries

and activate this option ('enabled').

Load it in bootloader mode (hold the reset button, then plug it to the usb cable), then put the newest firmware update. Worked here :)

Team

I had the same problem this AM. WE pushed the new firmware for the board and that didnt help either. INstead of a simple "SWD ERROR" we then started getting a "The interface firmware FAILED to reset/halt the target MCU".

Its possible that the new firmware (pushed as per below website) is giving a more descriptive error

https://developer.mbed.org/teams/Switch-Science/wiki/Firmware-LPC824

Andrea Corrado's procedure didnt help us. Heres what we did

1) Put the LPC824 chip in ISP mode

2) Pushed a sample code using FlashMagic using Uart0

3) rebooted the entire chip and the sample code worked

4) then we repowered the entire device and tried to use the NORMAL harddrive copy way and it worked

My theory is that the LPC824 is "stuck" in some kind of format and is not moving to ISP mode (which I am again guessing) is required for the program to be pushed from MBED into the chip. Once FlashMagic got involved it must have "cleared" the chip and all went back to being normal

These are wild theoritical guesses. BUT IT Worked :)

Any questions please dont hesitatte to write back

PEMicro OpenSDA firmware needs to be updated. The instructions for updating the board to PEMicro firmware is as follows- 1. Connect the board in bootloader mode 2. Copy the "BOOTUPDATEAPP_Pemicro_v111.SDA" file to the BOOTLOADER drive. 3. Unplug and replug the board (do no hold reset button). Check if board now opens in BOOTLOADER mode. 4. Copy the "MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA" to the BOOTLOADER drive. 5. Unplug and replug the board. Check if board opens as FRDM-KL25Z drive. Cheers man and fukc you!

Solve some probem wiht: :)

1) Plug Board in, wait for solid status LED

2) Press and hold reset button and at same time drag blinky on to Mass storage device.

3) Release reset and program should now load, no error.

Just started MBED, i got this issue and believe i solved my SWD error, blinky now operational again.

1) Plug Board in, wait for solid status LED 2) Press and hold reset button and at same time drag blinky on to Mass storage device. 3) Release reset and program should now load, no error.

Just disabled Storage Service in the services.msc, press the reset button. And it worked amazingly

https://drive.google.com/drive/folders/0B6fz4hKkIhQhb01hdVNYSjVYb0k?usp=sharing just go inside the folder and download it and then use the readme.txt folder All problems will be washed and you can use the FRDM KL25z easily

Same problem here. Any bin file that I try to load onto the board results in 'SWD error'

Guys did any of you solve the SWD Error issue? I did the same thing: I am just compiling the hello world program using the mbed online compiler. Once it is compiled, the binary file gets downloaded, which I copy into mbed usb drive. I reset the device, but nothing happens. When I view the contents of the USB device, it has a fail.txt which says 'SWD error'.

I am using Windows 10 and 2013 FRDM KL25Z with TFC shield connected standard to the freescalecup. Please let me know how to solve this issue!
