@qq20739111 I have this patch included in my latest build. I wonder if this will change the cooling and performance. I'll release a test image so you can perform a benchmark on it. I only have a heat sink and fan for the A7A right now. https://github.com/radxa/allwinner-device/commit/7716c3aacfe0ca4432ad3973ec7ea864d2b91195

No, just plain 100MBps eth.

@Nick A I didn't compile the image myself; I downloaded yours directly. What I meant is that when I running a CPU benchmark program, with all 8 cores fully loaded, the score using your image is about 30% higher than with the official image. However, the CPU temperature is also higher, even though I'm using the exact same cooling setup. By the way, that official heatsink seems to be out of stock now.

Any suggestions?

@Sergioclr you need to extract your Device Tree DTS. Does your box have gigabit Ethernet?
