Part 1: Understanding the CVTE-MSD338-512M Board

What does the model number mean?

• CVTE – The manufacturer (one of the largest OEMs for display controllers in China).
• MSD338 – The primary SoC (System on Chip), typically a MStar (now MediaTek) chipset. The MSD338 is a powerful video decoding and processing IC.
• 512M – Indicates 512MB of onboard DDR3 memory (RAM). This is critical because firmware built for a 1GB version will not work on a 512MB board.

• Read and agree to the terms and conditions of the software license agreement.
• Regularly update the software to ensure you have the latest features and security patches.
