New ZUBoard 1CG is not working

I purchased Avnet ZUBoard 1CG from Farnell UK, 1 month ago. Today, i plugged a good quality 15V/3A 65W USB-C power brick. All 5IN, 9IN, 15IN are red. LED D17 is green.SW2 Switches are default on QSPI as On-Off-On-On. After pressing SW7, I can not see any Virtual COM port on host PC and D23 LED is not lit. I also tried with another Linux PC. I could not see any logs about usb or FTDI when i type "dmesg". I have been struggling for 3 hour. I'm genuinely very upset. Because it has been 1 month, I wont be able to return for refund to Farnell in the case of hardware fault. I also verified USB Micro cable with another device. The cable does not have any issue. I attached a video describing the issue.

It looks like something fundamental is wrong. After you hit the power-on button there is a big white LED that should light up.

What happens when you connect using JTAG from Vivado Hardware Manager? Does it see the chip? Can you create a simple design that flashes the RGB LEDs and download it directly over JTAG.

I boot mine in SD card mode.

Currently, i don't have voltage measure tool. I will try to borrow from someone to test all points, later.

I think, it is not getting through on/off circuit. I can not see anything in Vivado Hardware Manager. I tried On-On-On-On JTAG mode. It is not working also.

I think even if jtag cable is not connected, we should see led lit when i press sw7.

I also dont have microsd card. I purchased today. I am waiting for it. I will try booting from sd card when it arrives.

My question is that:

If QSPI Memory is corrupted, will it run? I am remembering one of my previous boards were not enabling jtag when there is corrupted bootloader in booting memory.

Thanks for your advice. I wish we can access factory test also.

I agree with you about the power. It is not getting to the Zynq part. You say the +15V LED is turned on so that makes me think the USB-c power supply is working right and is negotiating to 15V. I had trouble finding one that did work. I finally used the power supply for my laptop computer.

The ZUboard has a lot of things that are extra complicated because Avnet wants to sell those special chips, like the usb-c power management chip.

You should get the big white LED lighted even if the QSPI is erased. You should not have to do circuit level debugging but if you can get a volt meter, maybe you can check the supplies.

Here is info on restoring QSPI image: https://github.com/Avnet/freertos-oob

I don't have ZUBoard but as I can see from the schematics, you will need to power the board (SW7) to get JTAG/UART interface. Which you are doing as per the video.

When D23 is lit, it is an indication of 3.3V is on. The power on sequence is triggered by pressing SW7. Try to push SW7 firmly, if that doesn't work, try to follow the link to restore QSPI image.

I tried JTAG boot mode by setting switches as ON-ON-ON-ON. There is no change.

I will try to restore using sdcard when my sdcard arrives.

When you tried JTAG boot, was D23 on? Or if you have multi-meter, you can test 3.3V?

Hi,

even if you don't have an SD card plugged in you should see the RGB, the Green, and 4 Red LEDs light up. Since you only have 60 days from purchase to return any defective boards, I would suggest you request an RMA and get a new board. Something may have occurred during shipping.

Hello, I have been using my ZUBoard again lately and I see the same problem you describe. I can set the mode switch to JTAG but I cannot attach to the board to download or debug if the SD card is not inserted in the socket. I have not checked the schematics to see how this might happen. You are using QSPI mode but the same issue may apply.

When there is no sd card and the boot mode switch(SW2) is JTAG, if you press the power on SW7, does any led turn on?

When i receive my sd card reader, i will flash with BOOT.bin in https://github.com/Avnet/freertos-oob. It looks like BOOT.bin includes first stage boot loader. If my QSPI flash memory is corrupted, it is expected to not power on.
