Help wanted to test a new OpenVFD alternative
Update I have opened the box. Indeed the driver is an FD6551 and the SOC is RK3328. I was using the FD655 just because that was the one used in a working vfd-openvfd conf file. So I have just changed the dtso file directive compatible = "fdhisi,fd6551"; The advantage is that 8 levels of intensity are now available using 1..8 in "echo 1 > /sys/class/leds/display/brightness". I did not chage the filename but as a matter of fact it should be as well the working rk3328-t9.dtso. rk3318-t9.dtso -

ESPRESSObin Firmware/Bootloader
DVFS has been working well for me on two devices for over a year now. Linux accepted my patch to re-enable 1.2Ghz in 6.15. I build my own Arch packages, but I started with ALARM. I didn't like the way they packaged the kernel and it wasn't being maintained. There are a few of us working on bringing Arch to aarch64. You'll find us on IRC. Libera.chat #archlinux-ports The ALARM project is a completely independent project of Arch Linux (despite the confusing name). I have no issues with random number generation. It was actually fixed by this project: https://gitlab.nic.cz/turris/mox-boot-builder which builds one component of the bootloader. So I use that project (instead of Marvell) for that part of the bootloader. -

Help wanted to test a new OpenVFD alternative
Both senteces are correct , I have reviewed the DT and now display-service is working properly and consequently there is no more sysfs "value" attribute. "Message" attribute is working as expected (scrolling, etc). Notes: It seems to me that the automatically generated dtso file for rk3328-t9 in the git repository is not valid. There are a lot of "T9" TVBOXES all around, mine is labelled T9-RK3328-8x4-V1.8 , (although I have always used it as an rk3318-t9 due to the main dtb file), so I will reopen it one of these day and be back. Anyway the latest driver is working as well with another box, another chip (FD650), please see:
