TE0841 Not detecting and consuming 2A current

(1/1)

srg:
Hello,

I am using following boards. I am observing Board is consuming around 2A current @3.3V supply and FPGA is not detecting in JTAG chain(JTAG Digilent cable is detecting). 

TE0841-02 SoM
TEBA0841-02 Daughter board.
TE0790-03 XMOD

Can anyone help me to debug this issue.

Thank You

Hi,
2A with our without design? What did you do before it stops working?
Did you use a heat sink?
Did you set HP bank power 1.8V? https://wiki.trenz-electronic.de/display/PD/4+x+5+SoM+Integration+Guide

Hi John,

QSPI memory was programmed with counter logic. The board/fpga running counter design for 3-4 days.
Heat sink with fan connected to fpga.

Thank You

Hi,
how did you supply variable bank powers(Jumper on the carrier)?
