This article provides details using a J-Link debug probe with either of these EVKs. There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or an external J-Link debug probe can be attached to the EVK. Using the onboard debug circuit is helpful as no other debug probe is required. However, the onboard debug circuit will no longer power the EVK when updated with the J-Link firmware. Appnote AN13206 has more details on this, and the comparison of the firmware options for the debug circuit. This article details the steps to use either J-Link option.
Using external J-Link debug probe
Segger offers several J-Link probe options. To use one of these probes with these EVKs, configure the EVK with these settings:
Remove jumpers J47 and J48, to disconnect the SWD signals from onboard debug circuit. These jumpers or installed by default.
Use default power selection on J1 with pins 5-6 shorted.
Connect the J-Link probe to J21, 20-pin dual-row 0.1" header.
Power the EVK with one of the power supply options. Typically USB connector J41 is used to power the board, and provides a UART/USB bridge through the onboard debug circuit.
