I was able to do exactly that with hqnicolas's 1.1 instructions and the .img he shared yesterday on Google Drive. I then attempted the openvfd with the results above. Thanks for any LED light you can shed....

@Hqnicolas I'm very happy to have booted and now running the latest Armbian trunk on my H96 Max V56 4GB/32GB! But I'm not having success using openvfd to get the time to display on the box's face. I only get the blue backlight and red LED heartbeat. I found your post here and a link to your github repo here. I followed the instructions, referring to my current kernel 6.6.45, but the instruction I understood the least was Step 3: 3. Update dts using armbian-config openvfd { compatible = "open,vfd"; dev_name = "openvfd"; status = "okay"; }; I interpreted that to mean sudo armbian-config, choose System, Dtc, and find some place to paste the above, save and exit, choose y to apply the changes, which produces a long set of warning messages like the following. ... /tmp/tmp.zItxtnh4vV/current.dts:4892.4-29: Warning (gpios_property): /gpio-keys-control/button-r1:gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4898.4-29: Warning (gpios_property): /gpio-keys-control/button-r2:gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4912.4-29: Warning (gpios_property): /gpio-keys-vol/button-vol-down:gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4918.4-29: Warning (gpios_property): /gpio-keys-vol/button-vol-up:gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4926.3-47: Warning (gpios_property): /mux-controller:mux-gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4926.3-47: Warning (gpios_property): /mux-controller:mux-gpios: cell 3 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4983.3-34: Warning (gpios_property): /sdio-pwrseq:reset-gpios: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:4989.3-27: Warning (gpios_property): /regulator-vcc3v3-lcd0:gpio: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:5018.3-27: Warning (gpios_property): /regulator-vcc-wifi:gpio: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:5062.3-52: Warning (gpios_property): /sound:simple-audio-card,hp-det-gpio: cell 0 is not a phandle reference /tmp/tmp.zItxtnh4vV/current.dts:5079.3-35: Warning (gpios_property): /audio-amplifier:enable-gpios: cell 0 is not a phandle reference Do you want to replace active dtb with current modification(s)? (y/n)y On reboot, there is no /proc/device-tree/openvfd so I assume I edited the device tree incorrectly? Aug 12 23:20:14 h96 systemd[1]: openvfd.service - OpenVFD Service was skipped because of an unmet condition check (ConditionPathExists=/proc/device-tree/openvfd). Any pointers on how to complete these changes so the clock appears would be very much appreciated. Cheers! watou

@Tressie, I'll post my results here when I can. I hope you can find a way out. Any chance of trying a different USB cable?

There's a link to the 8Gb mini loaded binary in this post linked below, and just use the latest official image for your TV box, like this one. Remember to uncompress the .xz image file before writing it, as I'm not sure the rk tools will do that for you. I've not done any of this yet, and I'm in a remote place trying to source a heckin' USB A to A cable!
