Michael,
Since I already had a system that is booting from your DE10 Desktop image, I
did the following:
sudo apt update
sudo apt -y install machinekit-rt-preempt socfpga-rbf
sudo fw_setenv fdtfile socfpga_cyclone5_de10_nano_uio_fb.dtb
sudo fw_setenv bitimage
/lib/firmware/socfpga/DE10_Nano_FB_Cramps.3x24_cap.rbf
fpga_on_boot = 1 was already set
so I did
sudo reboot
then made sure that it would still boot into the frame buffer
then I did
sudo fw_setenv bitimage
/lib/firmware/socfpga/DE10_Nano_FB_DB25.7I76_7I76_7I76_7I76.rbf
sudo reboot
then made sure that it would still boot into the frame buffer. So it looks
like I was just missing the stuff from pull 98. Then I went back into the
u-boot console and checked the variables and made sure everything still looked
good. It seems to be working.
