Mini ITX 7z100 + petalinux image

tommek — Thu, 18 Nov 2021 13:09:43 GMT

Hello,

I have dowloaded the official AVNET's petalinux-based sd card image from AVNET's webpage

link: https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/mini-itx/

image: Zynq Mini-ITX 7Z100 Petalinux Design v2015.2.1 (files BOOT.BIN and image.ub)

It does not, however, properly boot without HDMI connected into the box / board. I can't even observe complete U-Boot logs, so it must be shut down after the FSBL is run and FPGA is programmed.

With the HDMI cable plugged in (and the other end of the HDMI is plugged into a screen, obviously) everything works fine. But as soon as I disconnect the HDMI cable, the whole box is simply shutdown, i.e., the power is somehow cut off.

Is this a normal behaviour or there's something wrong with the hardware? (Note that there's also AD-FMCOMMS3-EBZAD-FMCOMMS3-EBZ from Analog Devices installed on the main board).

Thank you the help!

I've looked through the Mini-ITX documentation and can see nothing that would cause a shut-down with the HDMI unplugged. This is very strange. However, I have seen strange things in the past with poorly grounded power supplies. If the peripheral cable is providing a stable ground and is then removed, you could indeed experience very strange things. Or, it could be something completely different as well. Please let us know if you learn anything more!

RE: EMIO voltage level in zynq

bhfletcher — Mon, 29 Mar 2021 17:24:29 GMT

There are no EMIO pins, per se. EMIO is the internal channel between the PS and PL, which may or may not be pinned out to a physical pin. If you are talking about an EMIO channel that is pinned out to a physical PL pin, then the voltage definition of that pin is governed by the type of PL pin that it is.

On Zynq-7000, there are two types of PL I/Os -- HR and HP. You can see the voltage I/O characteristics in DS191. Both can support 1.8V.

Are you asking specifically about whether the Mini-ITX can set a PL Pin to 1.8V? Looks like Bank 35 is set to 1.8V. Banks 10, 11, 12, and 13 can be set to 1.8V if you short 3-5 on JP7.

EMIO voltage level in zynq

Is it possible to configure EMIO pins of zynq 7000 to 1.8 volts?

Is there enough space in the Mini-ITX Chassis to insert a PCIe card?
The picture of the chassis doesn't show that part, but the power supply and cabel seems to be very close.

We have seen SMT2 failures before. Does anything in this thread sound familiar? You could likely solve the problem by replacing the SMT2.

Cannot detect Ultrazed Board on host PC using UART and JTAG.

fpga programming using Ubuntu 18.04

amamory — Thu, 28 May 2020 21:51:22 GMT

Hello,

I am testing a mini-itx board with Ubuntu 18.04 host OS.

The tests with builtin software went ok. However, when i try to program the FPGA via this module

https://store.digilentinc.com/jtag-smt2-surface-mount-programming-module/

The USB device is not even recognized. I checked with 'dmesg' command. Nothing changes when i plug the usb in or out.

It seems that there are 2 possibilities:

1) there is a special device driver for https://store.digilentinc.com/jtag-smt2-surface-mount-programming-module/

2) there is some jumper to allow jtag programming that I am missing.

Reading the manual, I see that SW7[1] enables the JTAG Cascaded. I switched this on and off and nothing changes. The USB port is not recognized.

So, what is necessary to have the USB JTAG working on Linux ?

best regards,

Alexandre

I just want to add that I have other boards, such as zedboard, and I can program them without problems. The issue I described earlier is related only with mini-itx board.

Issue with PSiP Power Module of Mini-ITX-7Z-ASY-G

nafiseh — Thu, 21 Feb 2019 19:42:24 GMT

Hi all,

We have a Mini-ITX-7Z-ASY-G board, it is connected to the power module Panasonic PSiP. I have an issue that when I turn on the FPGA board, the power module doesn't turned on and it doesn't work. Can you please guide me how can I solve this problem?

RE: Issue with PSiP Power Module of Mini-ITX-7Z-ASY-G

nafiseh — Thu, 28 Feb 2019 17:43:28 GMT

Yes, the Panasonic is mounted; When I turn on the FPGA board the fan becomes on, but the LED lights on Panasonic power module don't turn on and the output from Panasonic Power Module doesn't come up.

RE: Issue with PSiP Power Module of Mini-ITX-7Z-ASY-G

ctammann — Wed, 27 Feb 2019 17:25:39 GMT

I assume you have the ATX supply connected to the board, as well as the Panasonic module mounted properly. What happens when you turn on the power switch? Does anything try to power up?

Thanks
Chris

PJTAG header & ARM debug problems

Former Member — Thu, 18 Feb 2016 20:59:12 GMT

Hi,

We are using MITX board with Linux kernel from Xilinx. Facing issues with linux kernel driver for USB, we are trying to debug it with Segger J-Link base with PJTAG header on the board.

I set-up DS-5 tools from ARM to work with J-link base. So it show s up as J-link USB in the connections section. When I try to connect to the ARM processor 0 or 1, the error I get is:

Could not measure total IR len. TDO is constant high.

The tool is reporting the correct information as I have verified the voltage on the header pins (5,7,9 & 13 for TDO etc..) to be about that.I have tried independent and cascaded modes but no help. Is there any way I can debug the problem?

Thanks,
Michael

Content of the debugging is done for the removal of the factors for the individuals. All the issues of the https://www.beezmap.com/profile/KathleenDFlores have been linked for the uploading of the pages. The route is donning for the approval for the actors for the bugging and its types.

Where can I download linux software for building mini itx image? Is it with petalinux?

Is there any wiki or document how to create image for the board ?

Issue with PCIe Root Complex reference design

olivierprogin — Fri, 20 Apr 2018 09:20:56 GMT

Hi everyone,

I recently tried to use the PCIe Root Complex reference design 2015.2 (available here: http://zedboard.org/support/design/2056/17 )for my master thesis project and faced some weird issues when trying to add a DMA to the reference design.

While booting, my linux system was receiving 100'000 interruption from the DMA causing the system to disable the interrupt line and causin the PCIe connection to stop working. A more detailed description is available here: https://forums.xilinx.com/t5/PCI-Express/Adding-a-DMA-to-a-PCIe-design/td-p/818174

Now that I had the time to investigate and solve this issue I would like to share the solution with you. To solve this issue, I had to restart a complete design only using the board description files and the constraint file (available here: http://zedboard.org/support/documentation/2056)

I then re routed the PCIe bloc with a clock and reset distribuation that made much more sense to me and this solved the issue.

You can find block design images on this forum topic here: https://forums.xilinx.com/t5/PCI-Express/Adding-a-DMA-to-a-PCIe-design/td-p/818174

I hope this could help anyone in the future

Can't Find Mini-ITX Files

Former Member — Fri, 13 Jun 2014 15:29:18 GMT

Could someone post a link to the downloads for the Mini-ITX Board? I'm looking for a good reference design to base a new project on. In the past I was able to find projects for this board on the site, but I can't seem to locate anything now. I've checked several places:

* Products Page - Mini ITX is not listed
* Support->Documentation Page - Mini ITX is not listed
* Support->Reference Designs/Tutorials - Mini ITX is not listed
* Projects Page - Mini ITX is not listed

I eventually found the Mini ITX Page (http://www.zedboard.org/product/mini-itx) using the search feature. The Product Brief download works but nothing else appears to be linked.

Not sure what I'm missing. If you could point me in the right direction I'd appreciate it!

Just use the interface "br0" in Pulsar Linux.

Can't start ethernet connection to Mini-ITX

portugese — Wed, 11 Apr 2018 06:25:07 GMT

Hello, I've got new Mini-ITX with Pulsar Linux. I connected it to network and set proper IP-address with netmask. And I can't connect to it. Even simple "ping" does not work. In both directions: from other computer to the board and from the board to other computer.

May somebody knows - what can it be?

Thank you in advance.
