@haven openvfd is long time deprecated. Armbian images have tm16xx driver which is far better and superior and x88 pro is supported out of the box via device tree overlay.

It is already mentioned in the first page under the "Special Hardware" paragraph.

Then you may want to follow the instructions on first page for boards without sd slot

@lopanrs ssv6051p is already supported out of the box with rk322x-box armbian images, you should not have to compile anything. Anyway this thread is about ssv6256p, which is another chip and requires another similar, but different, driver.

@Mitti Why do you say the board has no sdcard slot when the sdcard slot is just there? BTW, you have few options, but I suggest you not to use the NAND for the system at all. You can clean it completely, then the system will boot from sdcard, or you can use multitool to install the Jump step to boot from sdcard and USB stick.

Legacy is deprecated and long time discontinued. You'd better use mainline kernel with sdcard and forget the nand flash chip.

Three options: multitool boot armbian from sdcard and erase eMMC (or reinstall) from there keep "reset" button pressed (5 seconds will suffice) while turning on the board: armbian u-boot will immediately trigger maskrom mode

Hello, normally audio on Asus Tinkerboard works out of the box. I have not tested HDMI audio for a long time because I don't have a suitable monitor. It should work, but I can't bet on it. Analog audio also should work. You need to set the correct device to aplay because the default may be set to HDMI (or SPDIF). The command aplay -L will give you the various ALSA outputs you can play on, find something like plughw:CARD=analog,DEV=0 and then use -D aplay flag to specify the device. You should get something similar to this: aplay -D plughw:CARD=analog,DEV=0 my-audio-file.wav

Well I don't know what is that firmware and I'm not going to touch it even with a 6 meters stick, sorry. Random software from the internet is not a wise idea, even more if it is a software you are going to install onto a computer laying in your private network. About the serial adapter, I don't know, you should post logs or something useful to give you sensible guidance; giving you blind instructions won't help. If you're a newbie, probably it is better to wait for someone telling you a way to get maskrom mode on your board. I just want to ask you if you tried to put the multitool on a sdcard and boot the board with it.

Hard bricking is not compatible with the led flashing alternatively: you did not hard bricked the device, you're just having difficulties in changing the firmware. The maskrom pin may help, but also a serial adapter attached to the uart may let you solve the issue without maskrom. You could also tell us what is the bad firmware that makes your leds blink alternatively.

I warmly back @Werner suggestion; dkms for legacy wifi drivers is the best way to go (I only need to do it myself for some wifi drivers still laying around ...)

I have been able to download it from the first page, are you sure?

You'd better upgrade the kernel to 6.18 and keep Debian Bookworm, because Trixie has an mpv version which is not exactly friendly with hardware video decoding because some things are in the middle of a transition

@reinoldo vieira nice you found a pipeline that works with gstreamer! I have a couple of notes though: why using such an old armbian image with such old kernel? Current images are on Debian Trixie with kernel 6.18 (edge packages are on 7.0) hardware video acceleration is working for years on rk3229, there is a thread mentioned in first page to an ffmpeg repository to achieve that with mpv

@Suly rtl8703bs works with 8723cs driver, but the proprietary driver has been disabled so far in newer kernels because maintenance was becoming more and more complex. Actually I don't remember if it works with the mainline kernel driver. Probably it works, but I don't know if it is enable in rockchip64 kernel; it is surely enabled in rockchip armhf family.
