Which would you like? [1]:

Please input 2 or 3 for the EM1126B-P based on your application requirements.

Option 2: General-Purpose Board Configuration (boardcon_em1126bp_defconfig)

  • Framework: Based on GStreamer (Open-source, high compatibility).

  • Default Behavior: Automatically launches the Weston desktop environment.

  • Use Case: Best for general multimedia applications requiring plugin extensibility.

Option 3: IPC (IP Camera) Board Configuration (boardcon_em1126bp_ipc_defconfig)

  • Framework: Utilizes Rockit MPI (Rockchip proprietary). Provide modular hardware acceleration (VI, VO, VDEC, VENC, VPSS).

  • Default Behavior: Automatically launches the RKIPC daemon (RTSP/RTMP streaming & Web UI).

  • Use Case: Best for dedicated IP Camera products requiring optimized hardware acceleration.

Attention

Please ensure you select either option 2 or 3. These configurations are specifically tuned for the EM1126BP hardware. Selecting other options (or generic Rockchip configs) may cause kernel mismatches and prevent the system from booting properly.
