Part Number: UCD90120A
Other Parts Discussed in Thread: UCD90124A,

i'm trying to configure(its inside xilinx ac701 rev 2) my device with the "firmware & configuration download tool" but I get the following error:

"11:17:14.522 could not read DEVICE_ID from address 101: NACK; it is impossible to download a project file to a device if it's DEVICE_ID can not be read; this indicates a serious communication or firmware error that must be resolved".

I scanning for the device with the " UCD9XXX Device GUI" I pressed the "scan device in ROM mode" but all I got is "11:10:59.703 Found ROM v2 IC v2 - UCD30xx".

when I tried scan with the "DEVICE ID" button I get "11:12:41.998 No devices found"

the ac701card i'm working with is used but supposed to work.

thank in advance,

yuval.

Hey and thank you for the response,

I tried following the PDF and got to step 5, where i got a different value after pressing the calculate.

i'm attaching the GUI for further help.

As to what operation were made I don't know exactly, but someone got the board to this non-operating state by burning some wrong configuration file i guess.

thank you.

Hello

Based on the snapshort, you have the checksum 0x002E6350. Could you please confirm whether you have device UCD90120A or UCD90124A? These are two different products.
