Hi - thank you for the nice driver.

Also trigges are working. I still have this small bug which is stopping rolling messages: display-service -c [INFO] all digits and leds on /usr/sbin/display-service: 116: cannot create /sys/class/leds/display/message: Permission denied All the function leds reacts well (all on) but the four clock digits do not switch, most likey because of the message permission denied. However they do work writing directly in the "value" as above and in the picture. Edit: I have investigated a little and it seems that I am still using the tm16xx which came with the distribution, as depmod was failng. After a fresh recompile all your module load but nodes under "leds" are not there, it seems that the dtso/dtbo is not read - nothing appears in dmesg. Attached the working dtso file. rk3318-t9.dtso

I will try to upgrade to tm16xx driver and be back. As for the HDMI, do you mean that Multitool shoud work anyway? THKS

Still not clear why HDMI not working, However VFD display based n FD650 is working. Attached the vfd.conf file for openvfd: clock , USB, ETH,WIFI and COLON working. vfd.conf

Hi, thanks a lot for pointing me in the right direction. Indeed so far I am booting from the SD card. I have erased eMMC with multitool via SSH, as multitool as well is not visible via HDMI. Used the newer images as suggested, same situation: everything works via SSH cmd line, no output on HDMI. Log contains mainly errors as the ones posted above.

Thank you for the answer. Yes I will try the various dts, so far I have found that librelec - despiite not running at all, is crashing giving a visible prompt on the HDMI. I will try to compare that dtb/dts to the default rk3318-box and be back.

Hi, welcome everyone. I’m using an H50 TV box that I was about to throw away because I thought I had completely bricked it. I disassembled it and found the pins to activate maskrom mode. I think this could be useful for everyone. I then installed the current image, and everything seems to work except for the HDMI output (blank screen). Do you have any suggestions? Thanks. Some data and photo below. In case you want to install please note that also multitool fails to activate the HDMI, so you will need SSH to config.
