Hi Abv204 ;
The SW1UI3 and SW1UI4 buttons are usually used for recovering the image on the board. [More Information]
FM button (SW1UI3): The FM button, also called as FWR_RCVR, is used to recover an Intel Edison Board that has a corrupted software image. Powering off the Intel Edison Board, then pressing the FM button and then applying power will cause the Intel Edison Board to go to firmware recovery mode. Two recovery modes are available depending on the state of the RM button when the power is applied.
RM button (SW1UI4): The RM button, also called as RCVR_MODE, is used to recover an Intel Edison Board that has a corrupted software image. During boot, the state of the RM button will cause the Intel Edison Board enter into two different recovery modes. During boot, when the FM button is pressed (high state) and the RM button isn’t pressed (high state), the processor attempts to load the firmware from flash from the location specified in the UMIP header. During boot, if the FM in pressed (high state) and the RM button is pressed (low state), the processor attempts to download from USB Type B port, regardless of the UMIP header.
Were you following those steps?
Are you trying to see the boot process using an SSH connection?
If you want to connect your board to Eclipse you don't need to see the boot process you only needs to know the IP address of the board.
