Environment
| Name | Required | Notes |
|---|
| JLINK_DEVICE | Yes | Target device name, exactly as J-Link spells it (e.g. nRF52840_XXAA, STM32F407VG). Use the search_devices tool to find it. |
| JLINK_SERIAL | No | Serial number of a specific probe, when more than one is attached. |
| SVD_PATH | No | CMSIS-SVD file for the target. Without it, peripheral reads are undecoded hex. |
| JLINK_RTT_ADDR | No | Address of the firmware's _SEGGER_RTT symbol. Lets RTT survive a reset or flash. |
Tools show up when the registry metadata or the repository README lists them. GitHub enrichment fills this in when a token is configured.
