Common Limitations & Risks

• Memory constraints: 4MB limits features — no large web UIs, limited EPG storage, fewer user apps.
• Codec support: Limited to older codecs; modern formats or high bit-rate streams may not play.
• Security: Older SoCs may lack modern secure-boot; unsigned firmware or vendor backdoors are possible.
• Compatibility: Board-specific configs required — one image rarely fits multiple board revisions.
