8 Debug UART and Low-Power Sleep Mode
When the Intel® Edison compute module goes into low-power sleep, the UART internal FIFO and interface is
powered down. Therefore, a two-wire UART (Rx/Tx) will lose the first received character whenever the Intel® Edison
compute module is in low-power sleep mode. In order to avoid this condition, when sleep mode is enabled, a four-
wire UART (Rx, Tx, CTS, and RTS) is required.
Note: Low-power sleep mode is disabled by default in the latest image. To address this, update your firmware as
explained in the Getting Started Guide at https://communities.intel.com/docs/DOC-23147.
