Title: XMOD Unknow device issue TE0841-02Som,TEBA0841-02 and XMOD TE0790-03
Post by: srg on August 21, 2020, 07:25:42 AM
Hello,

In my setup FPGA is not detecting in JTAG.

I have following Hardware setup.
TE0841-02 SoM
TEBA0841-02 Daughter board. 3.3V Power is supplied through J3 5(3.3.v)-6(GND),  VCCIOA is set to 3.3V
TE0790-03 XMOD

all other setting are default.
When is try to connect device in Vivado hardware manager Digilent JTAG is detecting but Unknown device is showing.
Please me know what could be the issue.

Thank You.

Hello,
you see the CPLD from the XMOD or from the TE0841 module,

please check DIPs on the Carrier(TEBA0841):
https://wiki.trenz-electronic.de/display/PD/TEBA0841+TRM#TEBA0841TRM-DIP-Switch
-->S1-1 should be off for FPGA Access

DIP on the XMOD :
https://wiki.trenz-electronic.de/display/PD/TEBA0841+TRM#TEBA0841TRM-JTAGInterface
-->S1-1 should be ON, all other OFF

Is some of this DIPs maybe wrong?


PS: Pay attention with the other variable bank voltages, TE0841 has also HP Banks which supports max 1.8V:

VCCIOA is HR, so your setup is OK.

Able to detect FPGA after changing TEBA0841-02 DIP SW 1 position.

Thank You.
