I'm not getting HDMI display on either 5.10 BSP or 5.19 mainline With 5.10, the screen will turn black, so HDMI is being activated. But it seems the gpu fails to initialize: [ 15.337244] rockchip-csi2-dphy csi2-dphy0: failed attach dphy0 hw [ 15.343304] rockchip-csi2-dphy csi2-dphy0...

Sure. 1. convert dtb to dts 2. edit dts file - set fiq-debugger status to disable - set serial@fe660000 status to okay - remove console= from chosen bootargs - remove assigned-clocks from clock-controller@fdd00000 (pmucru) 3. convert to dtb

I was able to boot 5.19 kernel by modifying DTS See https://forum.armbian.com/topic/20065-random-rk3566-tvbox-legacy-vs-edge/?do=findComment&comment=154523

With 5.19.17 (Armbian_22.11.1_Station-m2_bullseye_current_5.19.17.img) I get stuck here: [ 0.000000] Linux vern 5.19.17-station-p2 (root@c0ef8c0946a8) (aarch64-linux-gnu-gcc lchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 8.3.0, GNU ld (GNU Toolchain for the A-profile...

I was able to boot the 5.10 kernel from https://www.armbian.com/station-m3/ after replacing DTB HDMI does not work but kernel and OS boot fully.

How can I extract it?

Did you ever try these out?

Did you have any luck? Maybe there will be better results with BSP 5.10 https://github.com/rockchip-linux/kernel/commits/develop-5.10

Anyone know where the WiFi chip is located? EDIT: LG642 is the WiFi chip. On another X96 board they use CDTECH 208821C

Okay I figured it out. 1. Save original boot/recovery headers ./rkdeveloptool rl 0x0c800 1 boot.orig ./rkdeveloptool rl 0x28036 1 recovery.orig 2. Overwrite with zeros to allow SD booting dd if=/dev/zero of=wipe bs=512 count=1 ./rkdeveloptool wlx boot wipe ./rkdeveloptool wlx recovery...

Does anyone know how to disassemble this box to get to the board? EDIT: Disassembly video:

I guess for JL2101 it needs some more patches which are not present in the armbian kernel image (but must be present inside android kernel image). https://github.com/CoreELEC/linux-amlogic/pull/13

I discovered my board has different ethernet chipset JL2101 http://www.t95plus.com/forums/index.php?threads/t95-plus-board.5/post-36

Another difference in my board, they replaced the RTL6211F with JL2101

I bought 5pc T95 Plus from https://zwin.en.alibaba.com/ In stock android, ethernet is working But when I use the armbian image, ethernet fails. I see this in dmesg: rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma eth0: stmmac_hw_setup: DMA engine initialization failed eth0...

After many attempts I could not make things work on macOS. I tried for example `rkdeveloptool wl 100 wipe_part` and `rkdeveloptool wl 320 wipe_part`. (The arguments are all in sectors, so 100 * 512 = 0xc800 for boot). In the end the only reliable way I was able to overwrite boot to force SD...

You can use these same instructions and img and it will work on X88 Pro 20

Thanks for sharing the photos. The RAM appears to be SK hynix H9HCNNNCPMML XRNEE. I think this is DDR4 SDRAM I opened my box up. It looks almost identical. But I did see one big difference: your eMMC is SanDisk but mine is Kimtigo. I guess they used a cheaper storage to save cost.

You can go into maskrom mode using rkdeveloptool as well. First go into loader model with USB-A cable + reset button trick. Then run `rkdeveloptool rd 3` and it will switch to maskrom mode.
