[Mbed OS 6.6.0] Flashing SDP-K1 board causes interface firmware to fail. Can no longer program board after flashing with any Mbed OS 6.6.0 project.

Description of defect

Flashing SDP-K1 with any Mbed OS 6.6.0 project appears to break the DAPLink update program preventing any more programming of the SDP-K1. Initial program will work, but any subsequent attempt to flash the board will result in a fail. Fail log is output with the following message: error: The interface firmware FAILED to reset/halt the target MCU.

Target(s) affected by this defect ?

SDP-K1

How is this defect reproduced ?

Flash SDP-K1 board with any binary/project using the Mbed OS 6.6.0 library (e.g. simple LED blinky project). Program will work initially. Try to program the board with any other bin/hex file after this first flash and interface firmware will start to fail consistently.

Last working on Mbed-OS 6.5.0.

Please check #14032

Checked this and configured the SDP-K1 so that the change in #13777 is disabled. Can confirm this is the issue, thanks Jerome. Will submit a pull request when #14032 is merged to change this option in master for the SDP-K1 to solve the problem.
