How to add pull-ups on DE10-nano GPIO

I'm trying to add weak pull-ups on JP7 GPIO1 of DE10-nano board. The board boots to Linux so as far as I understand FPGA image is loaded by Uboot from the rbf file on boot partition. There is a Def...

When I change my RFB with the original one from Terasic it boots fine.

Not sure if it helps, but I'd like to note that the LED pattern of the CD Default project and Terasic RBF is different:

Default project RBF (from CD) continuously switches between LEDs 1,3,5,7 and 0,2,4,6.

Terasic RBF (from SD card) briefly blinks LEDs 0,1,2,3,4,5,6,7 after boot and then only dowble-blinks user LED approx. one a second.

So I guess we are dealing here not only with RBF format/loading issue but also with different VHDL designs.
