How can I adjust VADJ value to 2.5 V on zcu102 Rev1.0 board?

[jenny_august13]

I am using FMC connectors on the zcu102 Rev1.0 board. And the board can only give 1.8V to the FMC adapter I am mounting on the HPC0 FMC connector. But the adapter needs a voltage of 2.5V from the board. How can I set the VADJ value to 2.5 volts for the following bord?Is it possible to do so?

Hi @jenny_august13,

You can adjust the VADJ voltage on the ZCU102. See AR#67308.

However, as per the ZCU102 User Guide UG1182, the valid values of the VADJ_FMC rail are 1.2V, 1.5V, and 1.8V.

This it is not possible to have a VADJ of 2.5V on the ZCU102 FMC connector

Regards,

Florent

Is it not possible to setTI MSP430 System Controller
[Figure 2-1, callout 18]
The ZCU102 board includes an on-board MSP430 with integrated Power Advantage demo
and System Controller firmware. A Host PC resident system controller user interface (SCUI)
is provided on the ZCU102 web page. This GUI enables you to query and control select
programmable features such as clocks, FMC functionality, power systems, and the Zynq
UltraScale+ MPSoC GTR selection compatible with your design. The ZCU102 web page also
includes a tutorial on the SCUI (XTP433) [Ref 11] and board setup instructions (XTP435)
[Ref 12]. The following briefly summarizes these instructions:
1. Ensure that the Silicon Labs VCP USB-UART drivers are installed.
2. Download the SCUI Host PC application.
3. Connect the micro-USB to ZCU102 USB-UART connector (J83).
4. Power-cycle the ZCU102.
5. Observe that SYSCTLR LED0 (DS47) blinks and LED1 DS46 is illuminated.
6. Launch the SCUI.
The SCUI GUI is shown in Figure 3-40.

The MSP430 uses ID resistor encoding to allow the System Controller utility awareness of

Hi @jenny_august13,

You won't be able to set VADJ to 2.5V even with the MSP430 as it is over the UltraScale board's VADJ capability

[jenny_august13]

Can I set the voltage VADJ to 0.0 V for the FMC but I have my FMC adapter connected to HPC0 has a specification for 2.5 V for Vadj.

Should I use an adapter that draws 0.0 V inorder to set the VADJ value to 0.0V . Is it not possible to set 0.0V though i have placed an adapter of 2.5 V over it? 

I am getting a timeout error when i tried to set the voltage as 0.0 V on System Controller User Interface in FMC options for Voltage.

The VADJ of the FMC card and the board are tied together. Do not try powering VADJ at 2.5V externally and you will risk damaging the HP Banks 65,66 & 67. 

What are you trying to achieve here by trying to power VADJ at 2.5V? 

[jenny_august13]

I want to make VADJ of the FMC card to 0.0 V onboard and is it a risk to give 2.5 V as an external supply to the adapter (4 ports ethernet adapter) mounting on FMC independant of the board.

How can I run system control user interface? I am unabe to get any voltage information over the GUI. And I followed the XTP435 and XTP433 documents. Do I need Vivado 2017.2 or SDSoC for that?

I have just downloaded the zip for SCUI and run the SCUI.exe.. But i can see nothing and i have also set sw6 to 1111 also and i can see DS46 illuminated and DS47 blinking.

An error while running ..... and a timeout occurred is being displayed for every action i perform on the SCUI.

Hi @jenny_august13,

Do you have an USB cable connected to the UART port of the ZCU102?

Regards,

Florent

[jenny_august13]

Yeah i do have and also the drivers.

[kvasantr]

Hello @jenny_august13,

Your drivers are not enhanced or updated properly.

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Please follow the above link and update your drivers to v6.7.

Also follow https://www.xilinx.com/support/answers/68521.html for more help in this case.

Make sure you are using correct version of SCUI application.

Please confirm silicon version of your board and download correct version of SCUI.

follow below link for the same:

Thank you.

I followed the link https://www.xilinx.com/support/answers/68521.html
and also gave the following port in the config.json also. But the same error exits

Hi I am using zcu102 es2 Rev1.0 board and i downloaded SCUI application with the name rdf0382-zcu102-system-controller-es2-2017-2.zip. And I am using v6.7.4.261 version of drivers

Hi @jenny_august13,

Do you see anything printed if you open an UART console (ex. tera Term)

[jenny_august13]

My uart ports are fine because I used them with putty to communicate on serial interface 0 on zcu102 and booted linux and did some tasks on it but i wonder why SCUI couldnot find the interfaces on the board. Any way will check using tera term.

[jenny_august13]

I can see nothing on the teraterm and here is the configuration of serial on teraterm

[florentw]

Hi @jenny_august13

I can see nothing on the teraterm and here is the configuration of serial on teraterm

-> You see nothing on all the 4 COM ports associated to the ZCU102? You should see something displayed corresponding to the power settings

[jenny_august13]

I can see nothing on all the four ports.

Hello @jenny_august13,

Try working with the older versions of SCUI.

Also install 6.7 version of drivers.

Thank you.

Yes this has worked for older versions of scui and from the following link

I came to know that for my board older than 2016.4 version os scui works
