In China, this 8+128GB only costs less than $75

@ Hqnicolas The network card is still unable to receive data, and the reason is unclear. In the past, connecting the network port was a simple task, but now it seems very difficult😂 [ 25.313329] rk_gmac-dwmac fe010000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 25.318206] rk_gmac-dwmac fe010000.ethernet eth0: PHY [stmmac-1:00] driver [Generic PHY] (irq=POLL) [ 25.321898] dwmac4: Master AXI performs any burst length [ 25.324480] rk_gmac-dwmac fe010000.ethernet eth0: No Safety Features support found [ 25.327033] rk_gmac-dwmac fe010000.ethernet eth0: IEEE 1588-2008 Advanced Timestamp supported [ 25.329956] rk_gmac-dwmac fe010000.ethernet eth0: registered PTP clock [ 25.333601] rk_gmac-dwmac fe010000.ethernet eth0: configuring for phy/rmii link mode

@Hqnicolas HDMI:✔ USB2.0 X 2: ✔ USB3.0：✔ Card Reader:✔ Thanks! Effective, all three USB ports can be used now.

Can anyone tell me how to repair the Ethernet port?

@Hqnicolas Could you please test the DTS that originally supported NPU? HDMI and WIFI are not working. Thank you. rk3566-h96max-npu.dts

vendor_6.1.43_minimal，directly using the one you modified can run WIFI normally, but I need to run NPU, so I modified it according to your DTB, but WIFI cannot run. Take a look at DTS, what's wrong? rk3566-h96max-npu.dts

I found that using your DTB can run WiFi, but I referred to your DTS to modify my NPU supported DTB. WiFi is not working properly. Can you help me check where the error is? rk3566-h96max-npu.dts

I seem to have noticed the problem. I have two boxes, one old and one new. The old one can set the CPU frequency normally, but the new one does not work. No firmware works, and the desktop firmware for station M2 has become invalid. The picture shows that the hardware sizes of EMMC are different. I think hardware changes are the root cause. The error message is shown in the figure.

Why can't the CPU frequency be adjusted in the armbian-config settings?

I used this method to test the DTB of this box, but in the end, it could only be partially started. Modifying the DTS requires professional expertise
