Power interruption – Even a 1-second power loss during update corrupts the bootloader. Update-over-USB vs OTA – Some versions only support USB update; OTA may show “no update available” even when one exists.
3. Best Practices for a “Better” Update A. Before You Start With only 512MB of memory, the board can
Identify exact PCB revision – Look for CVTEMSD338512M V2.0 or V3.0 on the board. Match panel model – Check sticker on LCD panel (e.g., BOE HV320FHB ).
