Hi Guys,
I have the 2017.2 Vivado project from github, I have built this and generated a petalinux buils which boots on the minized.
My next task was to add some IP, as an initial simple test I have just changed the axi_gpio_1 to dual mode and added an output mapped to M9, I have the following set in the constraints file:
set_property PACKAGE_PIN M9 [get_ports pl_gpio_test]
set_property IOSTANDARD LVCMOS33 [get_ports pl_gpio_test]
When I generate in vivado I get the following error:
[Place 30-58] IO placement is infeasible. Number of unplaced terminals (1) is greater than number of available sites (0).
The following Groups of I/O terminals have not sufficient capacity:
IO Group: 0 with : SioStd: LVCMOS18 VCCO = 1.8 Termination: 0 TermDir: Out RangeId: 1 Drv: 12 has only 0 sites available on device, but needs 1 sites.
Term: pl_gpio_test_tri_o[0]
If I look at the I/O bank properties in vivado the output is correct on bank 35, pin M9, LVCMOS33, output.
I'm a bit stumped by this, I have been using a zybo board before and have not seen this error before and there doesn't seem to be much about it on the internet.
Anyone got any ideas?
Cheers
Andy
