Hi Alan I would like to hear an updated status:
regarding the dtb (device tree) issue this should have been solved with the DE10..stretch ...img provided in the shared folder plus then installing the newer kernel .deb 's with sudo dpkg -i <kernel deb file namer here or *.deb> This should then provide the needed device tree (DE10...FB...dtb) in the /boot/deb folder, this dtb will then run the framebuffer and any DE10_Nano..._DB25 bitfile, provided in the rbf bitfile .deb package online .. including the DE10_Nano_FB_DB26.7I76_7I76_7I76_7I76.rbf. This bitfile needs to be loaded from u-boot before the kernel starts, AND machinekit must then not reconfigure the fpga while the system is running: No firmware load > If you are dependent upon programming the fpga before starting Machinekit > (ie: from u-boot before booting linux for framebuffer or similar) It is > possible to inform the hm2_soc_ol driver to not re-program the fpga by > issuing (already_programmed=1): > newinst HOSTMOT2 [HOSTMOT2]DEVNAME already_programmed=1 -- config=HOSTMOT2 > a working example of how to get this into a working .ini file is in the > example config (5i25-soc-cramps_no-fw-load.ini) here: > https://github.com/machinekit/machinekit/blob/master/configs/hm2-soc-stepper/5i25-soc-cramps_no-fw-load.ini This will soon be in the docs :) On Wednesday, 11 July 2018 01:49:30 UTC+2, mugginsac wrote: > > I couldn't get DE10_Nano_SoC_FB_DB25.vhd to compile without error (Version > 17.1), it had to do with version 17.1 and the "work" library.
