Is my microzed DOA?

Former Member

Hi All,

I recently received a Microzed SOM, but can't get any sign of life from the USB UART, which would suggest to me a power problem??

I must have made a mistake ordering the thing from AVNetExpress, because it didnt include the pre loaded SD card, cable and Xilinx licence. (is there a way to apply for this by the way?).

Also the boot jumpers were not populated, but there are what look like surface mount jumpers preset to QSPI mode. Should I remove these before soldering in some headers?

Many Thanks in advance.

    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.
