DAPLink¶

DAPLink is the interface on the MAX78000FTHR responsible for providing debugging, serial communications, and drag-and-drop programming.

If you are using MacOS the default DAPLink interface firmware will cause the MAX78000FTHR to reset after every serial connection. This causes issues for the eCTF. As such the organizers have provided a DAPLink binary that addresses this issue.

Download and Installation¶

Download the DAPLink interface firmware here: DAPLink_NoReset.hex

To flash this DAPLink interface to your development boards, utilize the current DAPLink interface. Enter into DAPLink update mode on the MAX78000FTHR by holding down SW5 and unplugging and replugging the USB connector on the board or toggling the power on the USB hub.
