CFGBVS pin default setting

Former Member
Former Member over 10 years ago

I'm trying to set the CFGBVS and CONFIG_VOLTAGE settings for a ZedBoard design. 

The Hardware guide v2.2 says JP4: "Pre-configuration I/O standard type for the dedicated configuration bank 0. Vcco_0 is 3.3V, Connected to 3.3V through a 10K resistor.  This jumper connects to GND and should NOT be used"

While I think that might be phrased better, seems pretty clear that what I need is

set_property CFGBVS VCCO [current_design]
set_property CONFIG_VOLTAGE 3.3 [current_design]

But earlier HW Guides (i.e. versions 1.x) say: "Pre-configuration I/O standard type for the dedicated configuration bank 0. Open sets bank0 voltage to 1.8V.  Default: Open"

Which ... well, seems not the same.

NB:  I have left JP4, unpopulated, obviously.

    Not sure if you have a question, but the current Hardware Guide, V2.2 is correct, the Bank 0 voltage is set to 3.3V. You have to go back to the version 1.6 of the Hardware Guide, from September of 2012, to find the error in the Jumper Table description.
