This page lists the known errors that are present in the 4Kopen Board (B2264).

Revision B

Analog Audio

When using the analog audio output, the user may notice significant noise on the output. This document outlines how to address the issue.

Note: if the analog audio output is not being used (e.g: you're using HDMI), then there is no benefit to conducting this rework.


MicroSD Card Operation at 1.8v

The rev. B boards do not correctly support SD Card operation at 1.8v, and thus high-speed signalling is unavailable.
