TE0745-03-72I31-A connector

For TE0745-03-72I31-A board, connector on board is ST5? so on my board, I need to use SS5 connector? are there cable between ST5 and SS5?

Hi,
yes Modules use ST5 and Carrier SS5 connector. You find ordering number here:
https://wiki.trenz-electronic.de/display/PD/TE0745+TRM#TE0745TRM-BoardtoBoardConnectors
There are no cable between the connectors.

We also offer the altium project of our carrier, in case you want to use it to start with your own project:

Hi John:
  To support TE0790, what is difference between J12 and J30on TE0745 carrier board.
  Can you send me picture of J1/J2/J3 pin orientation? I want to see where is pin on TE0745 carrier board of SS5 connector
   we don't have altium software.

Hi Brian,

you find the orientation and distance of the connectors on the ad file:
https://www.trenz-electronic.de/trenzdownloads/Trenz_Electronic/Modules_and_Module_Carriers/5.2x7.6/5.2x7.6_Carriers/TEB0745/REV02/Documents/AD-TEB0745-02.PDF



Different between J12 and J13 is the pinout.
J12 pinout is for usage with our TE0790 programmer, where you can use JTAG and UART together over USB.
J30 Pinout is for AMD Platform programmer or digilent HS3 programmer for JTAG only.

On TE0745-03-72I31-A board, BOOTMODE has pulldown.
This is for  QSPI mode or Jtag mode to boot?

Hi,
0: QSPI, 1 SD

https://wiki.trenz-electronic.de/display/PD/TE0745+CPLD#TE0745CPLD-BootMode

there is an optional firmware available which use Card detect pin from SD card to switch also to JTAG only, because writing QSPI flash with Vivado is not longer so easy possible if boot mode is not set to jtag only.

I didn't see MIO5 (bootmode1) on TE0745-03-72I31-A SS5 connector, but I also don't have plan to use SD card?
What should I do?
My plan is to use TE0790 to boot my daugther board for TE0745-03-72I31-A FPGA board.

Hi,
Bootmode_1 is only connected between CPLD and FPGA.

On default delivered firmware Bootmode_1 is constant 1, in this case you can only switch between QSPI and SD with B2B Pin J2-133 (Bootmode).

With newer Vivado Versions it's not longer so easy to program QSPI in case boot mode isn't JTAG only.

To have JTAG and QSPI as boot mode available update alternative CPLD firmware:
https://www.trenz-electronic.de/trenzdownloads/Trenz_Electronic/Modules_and_Module_Carriers/5.2x7.6/TE0745/REV03/Firmware/SC-PGM-TE0745-03_SC0745-03_20240219.zip
--> it's in the subfolder BOOTMODE_VAR-2

Update instructions:
https://wiki.trenz.local/display/PD/TE0745+CPLD+Firmware

In this case you can use MIO0 Pin (J2-137) to control Bootmode_1 signal to select also JTAG boot mode only.

On TE0745 there is unfortunately no other option to add JTAG only mode without changing B2B connector pinout.

On your carrier I would also recommand to make JTAG_EN (J1-148) selectable via DIP switch, this is need to get access to CPLD.

Hi John:
   How to find BOM file for TE0745 carrier board?

Good afternoon.

I'm not sure that we can share the complete BOM file. However, you are welcome to ask us about specific items that raise questions, and we will provide you with the exact part names.

Best regards, Maksim Tserabei
