Documentation on Microzed SBC (Upper Side Connectors)

vcasado31

Hello,

I have a Microzed with Zynq 7020 and the Micromod connectors in the top side. I have build a Petalinux image, and the FPGA Done blue LED lights up, but I cannot connect with the board trohugh any terminal (SSH/Serial).

I have looked for info, but I just got searching for Microzed SBC this following doc PB-AES-Z7MB-7Z010_20-SBC-G-V1, but no schematics/references...

Does anyone can ping me some short of documentation about this board, please?

Thank you!

    Because the FPGA "Done" indicator is on, we should be able to assume you have a bootable image on the device.

    1. Is it booting from where you expected?  (onboard eMMC, uSD card, etc)

    A number of things could be at play here.  In no particular order and no offense intended:

    1. Is the Ethernet hooked up and network configured on the uZED?

    2. Did you include the components necessary for SSH in the image?

    3. you actually mean using a real serial connection and not SSH, is a known good USB cable connected between your host and the uZED carrier board?

    4. Does the /dev/ttyUSB<x> device(s) show up?  If you're unfortunate enough to be doing this from a Windoze machine, did the COM<x> port show up?  If more than one, did you try all of them to connect to?

    5. Is the port configured correctly for 115,200 Baud, 8 bit, no parity, software (not hardware) flow control?

    More information about your configuration is necessary to help narrow this down any further.

    Hi, thank you so much for the answer!
    I will answer one by one with the situations:
    1. I think that yes, I I remove the SD the FPGA Done does not light, so I think that it boots right from the SD
    2. Yes, I did
    3. Yes I hoped to use the Micro USB on the board, but I then figured out that that USB is connected to the USB3320 USB Transceiver, not to the CP210x UART bridge, and in the link above it does not mention to have USB-UART communications, that is why I need the schematics to see where I can get the UART port.
    4. No, I tried on both, Ubuntu and Windows and it does not appear in none of them.
    5. yes
    Thank you!!

    I don't have my uZED board in front of me so this is all from memory.

    It sounds like you're talking about the PS microUSB connector.  That's not going to work. 

    I pulled up the schematics and data sheets on the uZED and it suggests 2 USB connectors but I only see one in the pictures.  Is the Ethernet a combined Ethernet/USB A?  If so, the uUSB is the USB to serial connection and is the one you need to use.

    Hello,

    I am using the AES-MBCC-IO-G carrier, but I think that it should not be necessary, as the Microzed is the SBC not the SOM version. That is what I need, the schematics for my Microzed, this version does not have the combined Ethernet/USB A, it just have a Ethernet,and the uUSB in the side.

    Thank you!

    I'm not familiar with a SBC Variant of the MicroZED.  All of the MicroZED boards I've known are SoM and require a carrier card.

    Looking at the schematics and mechanicals, I see the uUSB for the serial console/power and a combined Ethernet/USB-A stacked connector. If your board is different, I can't help any more.  I wish you the best.
