They can put a request in for you. Generally though, the User Guide in the case of FMC has the information you need for FMC does it not?

Seems right. Not sure what else could be wrong. Trying things on the Alinx card instead. Guys, you've got to make the schematic available. Obfuscating this is not ok, no other eval board vendor would do this.https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/zuboard/56976/can-i-connect-a-fan-to-power-it-to-usb-2-0-port-of-zuboard-1cg/235770Sat, 23 May 2026 06:10:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1f342599-438a-47a4-b8c5-8bbea77718e6iksevasThe USB 5V is powered with 900mA device.

What can be the max current that this fan is allowed to draw from USB 2.0? THANKShttps://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/zuboard/56976/can-i-connect-a-fan-to-power-it-to-usb-2-0-port-of-zuboard-1cg/235755Fri, 22 May 2026 15:21:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5da89d29-e7ad-4231-85c1-24fba7bd46e5iksevasI don't believe a FAN has been tested, but the USB2.0 port is powered with 5V that gets generated from +SINK_PWR and is sequenced with EN3 signal. Because it is sequenced, the board will need to powered-on before the fan will turn on, ie - simply plugging in USB-C may not power the fan. There is a mode where plugging-in USB-C is possible to power-on the board skipping the push-button. A resistor would need to be moved on the board. See the INIT signal on the power controller and the gray box. This would allow the fan to turn on (and the board) when plugging in the USB C cable directly.https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/zuboard/56976/can-i-connect-a-fan-to-power-it-to-usb-2-0-port-of-zuboard-1cgFri, 22 May 2026 10:46:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d6e236a3-adb0-44af-981d-1bda4dab2503MadhusudhanRHi, I am planning to develop an enclosure to the ZUBoard-1CG & would like to add a fan. I want the fan to be powered ON as soon as the board gets the power through USB-C. For this, I plan to use USB fan which draws less current & connect it to USB port of the ZUBoard-1CG Can I connect?

Swapping the resistors made it such that the FMCOMMS2 comes up, LED is lit, chip can be talked to over SPI and registers can be set. So the AD9361 is up - but the AU15 RX I/O on the FMC interface is completely dead, and that's the part I'm no able to change. Testing the same logic on the Zedboard (ported to 7-series) worked fine...https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/auboard-15p/56958/fmcomms2-fmc-on-au15p/235683Wed, 20 May 2026 15:47:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d50e7cb7-2fac-4191-9b72-3f6b8335696diksevasIt looks like PG_C2M is required for that FMC card to function and Rev 1 of the AUBoard has a BOM issue where the pull-up to enable this is not populated. It is resolved in Rev 2 due out next month.https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/auboard-15p/56958/fmcomms2-fmc-on-au15pTue, 19 May 2026 12:40:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:0b1ec461-a4f7-4744-a768-c618e2ac891dvadimvHello, Struggling to get the AD9361 to actually pass any sort of data back to the AU15P. The SPI is working ok, i can talk to the chip, but all LVDS data stays at 0. The AU15P J46 jumper is set so things are running on 1.8V as they should, yet there is no LVDS activity at all. The AU15P uses HD pins for LA_07_P/N, but regardless of how that's pinned out, the other LVDS pairs ought to produce something. Here, IDELAY passes nothing into the FPGA on the receive side. Have FMC designs worked on this board before? Has AD9361 testing ever occurred? Now that this board is being replaced, can we get a schematic of the current version?https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/ultrazed-hardware-design/56923/ultrazed-som-issue/235472Fri, 08 May 2026 20:11:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:2acb7ecd-29c4-41aa-b1db-26aceecaab7eiksevasThe BSPs for various tools versions are posted on a Sharepoint site. the code base used to generate those BSPs are on Avnet GITHUB.https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/ultrazed-hardware-design/56923/ultrazed-som-issue/235466Fri, 08 May 2026 18:16:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d956c1ff-6155-49fb-90eb-1a8b7f9208e0chasekimHello, iksevas, Can you please let me know you built in design file and BSP of the PetaLinux. I want to know the difference between the two hardware versions. As i know that two device is same FPGA core.... Thanks,https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/ultrazed-hardware-design/56923/ultrazed-som-issue/235454Thu, 07 May 2026 21:30:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:33fb1d7e-7513-4c3b-9149-a6bfd3d6c3e8iksevasAny chance you can measure the eMMC clock? I would be curious to see between the two SOMs if the clock is changing frequency during the boot process. as far as determining if there is a build difference between your boards, I would look closely at the eMMC devices on the two boards and check to see if those are different device somehow. Could be as time and device availability could result in changes. Typically, the factory programs QSPI and eMMC with Linux out of box image. Perhaps it would make sense to get that reprogrammed onto SOM and see how that functions.https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/ultrazed-hardware-design/56923/ultrazed-som-issueThu, 07 May 2026 20:36:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f885bc53-1a81-433c-86e4-9fa0ab592e89chasekimHello, I have a problem for new purchased of UltraZed SOM about the MMC access error by FSBL and I2C-2 read error, seems to be slow booting time via EMMC.
