Hello all! My first message, and of course about problems. Thanks @jock, @fabiobassa and others for this work!
I have a board with rk3229, 2gb ram ddr3, 8gb nand, esp8089 with 26MHz crystal. Just solder microsd slot to existing pads on pcb and install Armbian_21.08.1_Rk322x-box_buster_legacy_4.4.194_xfce_desktop via Multitool. Everything works except wifi. Module esp8089 is loaded and wifi0 exists, but can't see any network. I carefuly read a conversation with @victronikoat page 13 of this topic, try a different overlays and modules, no luck. Any change make wifi init impossible. My opinion is module esp8089 don't accept config=crystal_26M_en=1 at loading, but i can't uderstand why.
Some bits from dmesg and other:
Also i extract a device tree from genuine firmware, part about wifi:
Also i try Armbian_21.05.1_Rk322x-box_focal_legacy_4.4.194_xfce_desktop with same result. Any suggestions?
