Yes thanks for mentioning this. I will need to keep an eye on this as my initial bring-up of the Rock3A also resulted in block errors after 2 days. Was another SD-card (new one). But I did many reboots/trials and 3 different U-Boot versions, 3 different kernel versions, also not to forget various powering options. So cannot really conclude anything from it. Note that I use Btrfs, so already the kernel detects block corruption. Usually that says enough. See also comments inside script: /usr/sbin/fsck.btrfs If a DISCARD command fails (I/O error), it should not corrupt used blocks, unless the SD-card internal firmware makes a total mess of things or due to some wrong administration in fstrim/kernel. I bought this Rock3A for its SPI flash and SATA, so I can put Btrfs+SATA enabled U-Boot in it, then the board itself can boot from Btrfs raid1 profile (SD-card+SATA-HDD), even with SD-card totally failing. So that I could use to detect issues with SD-card (anything, even A2 queing etc if that is the case, I haven't focused on it). And keep it running. But it is easier to raid1 an SD-card partition + an NBD image file on NAS (TFTP boot), I have done that before. Then no changes in default U-Boot needed.

Yes, H616 Cedrus is capable of decoding VP9, but I'm not aware that anyone actually implemented support for it.

@jock It worked! thank you very much! There are already 2 WLANs: WLAN0 and WLAN1 hmm.. ip_a-v9.3.txt lsmod-v9.3.txt dmesg-v9.3.txt

It's working! Thank you so much, you've been a huge help. These challenges have really helped me understand device trees and hardware configuration. This forum is amazing!

@Obmor here it is a module for kernel 6.6.67 and rtl8189es. Put this module in /lib/modules/6.6.41-current-rockchip/kernel/drivers/net/wireless directory, then run sudo depmod -a and reboot. If everything went ok, you should get 8189es driver loaded after boot; perhaps you may need a firmware to put somewhere in /lib/firmware. In case, the driver should complain about in dmesg that something is missing or wrong, and that may serve as hint to proceed further. 8189es.ko.gz
