Reprogramming SWDAP

When a new SWDAP is plugged in to your machine, it will not contain valid any firmware, and so will appear as a disk drive called "CRP Disabled" as.

To progam the SWDAP, follow these steps:

• Open the drive, and delete the file called "firmware.bin"
• Download the required image from the table above (or built your own using DAPLink project)
• Copy the .bin file onto the "CRP Disabled" drive.
  • On Windows, replace firmware.bin with the above firmware
  • On Linux/Mac, use command: dd if={new_firmware.bin} of={firmware.bin} conv=notrunc
• Unplug your SWDAP, and plug it back in
• It should now appear as a disk drive called DAPLink

You can re-program your SWDAP at any time by plugging it in with the button held down. This will cause it to appear as the "CRP Disabled" drive, at which point you can follow the steps above.
