Reprogramming SWDAP
Step1: Install the last serial driver
Step2: Plug in micro USB to PC
- 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.
