This is the documentation for the latest (main) development branch of Zephyr. If you are looking for the documentation of previous releases, use the drop-down list at the bottom of the left panel and select the desired version.

A debug probe is used for both flashing and debugging the board. This board has an OpenSDA Onboard Debug Probe. The default firmware present on this probe is the OpenSDA DAPLink Onboard Debug Probe.

Based on the host tool installed, please use the following instructions to setup your debug probe:

• J-Link Debug Host Tools: Using J-Link on NXP OpenSDA Boards

• LinkServer Debug Host Tools: Using DAPLink on NXP OpenSDA Boards

• pyOCD Debug Host Tools: Using DAPLink on NXP OpenSDA Boards

Using DAPLink on NXP OpenSDA Boards

1. If the debug firmware has been modified, follow the instructions provided at OpenSDA DAPLink Onboard Debug Probe to reprogram the default debug probe firmware on this board.

2. Ensure the SWD isolation jumpers are populated

Using J-Link on NXP OpenSDA Boards

There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or a J-Link External Debug Probe can be attached to the board.

To update the onboard debug circuit, please do the following:

1. If the debug firmware has been modified, follow the instructions provided at OpenSDA J-Link Onboard Debug Probe to reprogram the default debug probe firmware on this board.

2. Ensure the SWD isolation jumpers are removed.

To attach an external J-Link probe, ensure the SWD isolation jumpers are removed, and connect the external probe to the JTAG/SWD header.
