TEB0745 power pin / TE0745 serial
« on: July 05, 2018, 04:40:31 PM »
Hi,

Polarity for the 24V power for TEB0745 at the J31 green connector?

https://wiki.trenz-electronic.de/display/PD/TEB0745+TRM

says

24V on J31:

    J31-1: 24V
    J31-2: GND

- Is J31-1 the one with a dot?  I.e. the one towards the board?


- If I understand correctly, there is no serial interface (also not via USB) for the TE0745?

- With nothing else connected than network, (e.g. no PL program), the only way to see if the TE0745 operates is via network, and an SD boot image which have a well configured network interface to log in to the PS?

Hi,
JTAG and UART access over J12 (next to the power supply J31):
You need USB-JTAG programmer. Pin header is for our TE0790:
Power over J31 Pin 1 (the bigger dot next to J31 label) for 24V Pin 2 for GND, see also:I've also add a picture on:You can boot from SD or QSPI also. QSPI is accessible over JTAG with Xilinx tool.
Basic links to all currently available resources:We have also a 2017.2 reference design:2018.2 design updated is planed.

For the TE0790, the default settings (S2-3 OFF, S2-4 OFF) will not power the USB chip from a TEB0745?

How should they be set?
