AIB-SO21/AIB-SO31/AIB-SN31/AIB-SN41 User Manual 26
3. Software/BSP Installation
Aetina NVIDIA Jetson products have built-in BSP so the users don’t have to install it after getting the
products. Since we develop our own BSP, the users may need to follow the BSP installation SOP to
re-install/upgrade/downgrade the BSP. Please visit the Aetina website or contact with Aetina FAE at
Tech_support@aetina.com for installation guides, BSPs and technical tips.
