Is my microzed DOA?

Sounds like what you ordered is the one of the MicroZed 'Cost Optimized' SOMs ( AES-Z7MB-7Z0x0-C01-x-G  ), which is designed to work only with a Carrier Card of some sort and is not powered from the USB UART connector as the other MicroZed versions are.

There are three basic ways to order a MicroZed:

1. The MicroZed Evaluation Kit, which comes with a 7010, commercial temp version of the SOM (System On Module) along with a license voucher, cables,and a microSD card. I would note that the microSD card is not pre-loaded but you can download the image from the microzed.org site. AES-Z7MB-7Z010-G 

2. A MicroZed SOM that comes with only the SOM (no license voucher, cables, or microSD Card). This is available in four versions covering 7010 and 7020 versions with both Commercial and Industrial temp options. AES-Z7MB-7Z0x0-SOM-G or AES-Z7MB-7Z0x0-SOM-I-G 

3. The Cost Optimized MicroZed SOM which, like the MicroZed SOM, comes in the four versions and has no cables, voucher or microSD card. This version costs a little less and is intended for production where the customer is going to operate only in a carrier card environment where power is supplied by the carrier card as well as the JTAG connections. The boot options are fixed as well as a couple of other changes such as no user LED and push button. AES-Z7MB-7Z0x0-C01-x-G 

All of the MicroZed versions are covered under the free Xilinx Vivado Webpack version. The free Webpack version does not include the Vivado Analyzer (ISE Chipscope) option. So, if you plan to user your MicroZed on a Carrier Card and do not need the Vivado Analyzer option you should be OK with your current board and have saved some money. You can remove the boot option shunts and replace with a header if you wish. If what you need is a standard 'stand alone' MicroZed SOM, and possibly a license voucher, then you will need to contact Avnet Express for an exchange.

Thanks for the fast reply Gary. Yes, I think i do have a cost optimized version, which is slightly disappointing, it's a little unclear on the avnet website.

I suspect exchanging the board may be expensive (I'm in the UK and had to ship from USA), is it possible to solder barrel jack and use that?

Is there anything stopping me from putting a JTAG header on the board itself? looks like a standard 2mm surface mount job.

Kind Regards,

Ben

All of the differences between the 'standard' and 'cost optimized' MicroZed versions are just Bill Of Material (BOM) and component place - don't - place options, so any of the MicroZed cost optimized differences can be changed by additions or removals from the PCB. So you can add a JTAG header as well as a barrel jack (take care and follow the instructions in the Users Guide if you plan to use 12VDC instead of 5VDC). Or you can add the diode and modify the board to be powered via the USB connector as the other MicroZed versions are.

Take a look at the MicroZed Hardware Users Guide as well as the MicroZed schematic for guidance. If you download the MicroZed Bill Of Materials (BOM) zip file it will include one for the cost optimized version with the differences highlighted so that you can easily make of the changes you wish.

I am in the same situation, but I just ordered the i/o carrier board @ $149. Will I be able to program and configure the AES z7MB-7z020-C01-I-G SOM with the carrier board in the same way as a standalone AES z7MB-7z020-I-G SOM can be programmed and reconfigured ( JTAG, USB, ethernet, etc) ?

More importantly, If I decide to keep and use the AES z7MB-7z020-C01-I-G SOM will I be able to program it with the carrier board, and then make it  work independently on its own without the carrier board (i.e. as minicomputer running other peripherals with a battery powered source)? Is the AES z7MB-7z020-C01-I-G SOM always dependent to the carrier board in order to run?

The Cost Optimized MicroZed will need to be powered via the JX1 / JX2 connectors, unless the board is modified to receive power from the USB connector or the barrel jack is added, so in that sense it is dependent on carrier board.

While your MicroZed is connected to the IO Carrier Card you will be able to use the JTAG connector on the IOCC to program the MicroZed via JTAG. The boot option straps are fixed to QSPI boot mode.

So, you will be able to program and debug your MicroZed via JTAG when connected to the IOCC carrier board. If you want to boot from a source other than the QSPI you will need to remove the fixed boot option jumpers and replace with either a header or another fixed jumper setting. You will be able to operate your MicroZed independently as long as you supply power via the JX1 / JX2 connectors or modifiy the board to accept power via the USB connector or barrel jack.

I get the following errors when I try to program the microzed card through carrier card:

ERROR: [Labtoolstcl 44-26] No hardware targets exist on the server [localhost]
Check to make sure the cable targets connected to this machine are properly connected
and powered up, then use the disconnect_hw_server and connect_hw_server commands
to re-register the hardware targets

This post is really not related to this thread. Please start a new forum thread.

Include information on which MicroZed you have, your Xilinx tools version, your host PC OS, what type of carrier card you are using, and what JTAG cable/adaptor you have.
