TE0729 Removing Pin from design crashes device tree creation

[chris_est]

Hello,

adding an external pin in the Vivado Design based on the TE0729 Trenz Reference Project (Vivado 2016-02) and removing it in the next synthesis, then exporting it to hdf and trying to rebuild petalinux (with petalinux-config), it crashes when trying to create the device tree with the following error:

The constraints file (.xdc) still holds a record of the removed pin, but the synthesis and bitstream creation succeeds.
Also removing the dead entry does not fix the device tree creation error mentioned above.

Is there a special way to remove previously used pins in a block design ?

i do not think it is related to top level pin, the error is something with interrup binding, make sure you have all inputs to the concat at interrupt input connected and the concat size is correct.

in any case the issue is not related to TE0729 or any our products, this is some "internal" Vivado thing
we are also struggling with small nasty things, like if you add more ports to ILA, then change their width and then reduce the port count, then Vivado will crash or not create bit file, your problem seems to be similar, but we do not know one single solution.

in generic, ALL works if you do all from scratch, when changings the stuff, then sometimes small issues happen.

The way Vviado makes DRC checks is different of what the HSI TCL does when generating the DT
