TSW14J56EVM: DDR3 dont pass calibration and initialization

Part Number: TSW14J56EVM

My customer bought four development kits: TSW14J56EVM + ADS54J40EVM

 

Three dev kits work correctly.

 

On one of four TSW14J56EVM boards when data is collected  an error occurs – screenshot in attach.

 

On the board is not working two status LED D6 and D7 is “On”, D8 is "Off", and D4 – is blinking


As I understood from User’s Guide for TSW14J56EVM problem wth initialization DDR3…

 

How to solve this problem and return the workability of TSW14J56 board?


  • Hi Maxim,

    If LED D7 and D6 are on then there is an issue with the DDR memory. When the firmware is loaded, the first thing it does is a DDR memory test. If the memory is bad I would suggest returning the board to your vendor for replacement.
