Do you need help or have general support questions, than I hope this page helps you resolve those.  

This  page has a quickstart troubleshooting approach that goes over some very general questions and common pitfalls, but if you have a specific issue which requires more information or detail please contact us through EngineerZone or Email. (links can be found further down on the page where to direct specific questions)

===== What to do When Things Go Wrong =====

There are many things that can go wrong with an ecosystem this complex, but if you are having issues getting the board or software working, here are a few simple things you can try before contacting Analog Devices.

  - Check the Power
    * Do you have the USB cable plugged in? if yes, then check switch (S7) in USB position
    * If you are using batteries, is the switch (S7) in the "BATT" position
      * Try replacing your batteries, and see if the board powers up.
  - Program the EV-COG-AD4050LZ
    * Sometimes a flashed program doesn't run properly or can make it difficult to run the debugger. 
    * The first thing to try in this case, is to [[resources:eval:user-guides:ev-cog-ad4050lz:tools:hardware_usb|drag and drop]] a known good .HEX or .BIN program into flash.(something with quick visible indicators works best)
    * If drag and drop is not working, it may be necessary to erase the flash. To do so:  
      - Download and install the CrossCore Serial Flash Programmer from here: [[adi>en/design-center/processors-and-dsp/evaluation-and-development-software/crosscore-serial-flash-programmer.html#dsp-overview]].  
      - Make sure that the USB is connected and on UART header (P8) 1 & 2 and 7 & 8 are shorted. 
      - Power cycle the EV-COG-AD4050LZ board while holding down the boot switch. 
      - Select the mbed serial COM port in the CrossCore Serial Flash Programmer, and erase the flash.
      - Then try [[resources:eval:user-guides:ev-cog-ad4050lz:tools:hardware_usb|drag and drop]] a .HEX or .BIN file into flash
    * If the mass erase didn't work, and you are trying to drag and drop a large .BIN file on EV-COG-AD4050LZ hardware, it's possible that the mbed interface file needs to be updated to support your application.
      - Please visit the [[resources:eval:user-guides:ev-cog-ad4050lz:tools:hardware_usb|Driver Installation for On-board Debugger (CMSIS DAP)]] page in order to put the board in update mode.
      - Once you are in "maintenance mode" you should drag and drop the latest interface file onto your maintenance drive.  That file can be downloaded at the bottom of [[resources:eval:user-guides:ev-cog-ad4050lz:tools:hardware_usb|Driver Installation for On-board Debugger (CMSIS DAP)]].
  - Not receiving/transmitting data to the UART
    * Make sure that the UART header (P8) is positioned in the correct destination to transmit/receive UART data.
