3.2 SAM-BA®: No J-Link Device Found

The SAM-BA tool is unable to detect any J-Link programmer interfaces on the system. This issue is often due to an unsupported debugger connection, hardware setup issues, or an incorrect board state.

It is recommended to tie the JTAGSEL pin to GND. If JTAGSEL is tied high, the device enters Boundary Scan mode, and SAM-BA is not accessible.

Note: Only SEGGER SAM-ICE™ and J-Link J32 probes are supported for programming via SAM-BA commands. PICkit™ and ICD tools are not supported. To program with J-Link, refer to the sam-ba_v3.9.2/doc/port.html file, available in the SAM-BA v3.9.2 installation folder. See References.
