CMSIS Documentation

This package uses Energy Micro's CMSIS files exclusively for device headers and core support.

Debugging capability

The EFM32 serial wire debug supports SW-DP and not JTAG-DP. As the CrossConnect Lite and CrossConnect Classic do not support SW-DP, you cannot use them to debug the EFM32G.

If you need to debug an EFM32G you can use a recent Segger J-Link. Alternatively, you can use an FTDI-based JTAG adapter, such as the JTAGkey or JTAGkey-Tiny, together with our Cortex SWD Adapter. Please check to ensure that your FTDI device is compatible with our adapter before attaching!
