  1. I improved the dts of Phicomm N1 again. The reasons are: 1. The Ethernet card of N1 is not very compatible with some switches. When the ethernet phy is activated, the flow control sometimes cannot be turned on, so will get bad results during the speedtest.net . For this reason, I added a dts separately force_thresh_dma_mode, which is equivalent to flow control in software mode. But there are also side effects: tx performance is reduced. In addition, as auxiliary optimization items, set snps, aal; snps, txpbl = <0x8>; snps, rxpbl = <0x4>; their role is to improve the performanc
  2. hi lewis: Yes, i am happy to share it。 The main body of those mirrors is from the ambien community. I just recompiled the kernel on the results of others, using the kernel source code from 150balbes, and added the dtb file for beikeyun, you can use it at will. rk3328-beikeyun-1200mhz.dts rk3328-beikeyun-1296mhz.dts rk3328-beikeyun-1392mhz.dts rk3328-l1pro-1296mhz.dts rk3328-l1pro-1392mhz.dts rk3328-l1pro-1512mhz.dts
  3. In the mainline kernel, meson-gxl-s905d-phicomm-n1.dts has been around for a long time, but there has been a problem of high CPU load. I fixed it and it has been stable for several months, so it is shared for reference . I think the cause of the problem is that the IRQ is wrong. The original value is 29 and needs to be changed to 25. // SPDX-License-Identifier: (GPL-2.0+ OR MIT) /* * Copyright (c) 2018 He Yangxuan */ /dts-v1/; #include "meson-gxl-s905d-p230.dts" / { compatible = "phicomm,n1", "amlogic,s905d", "amlogic,meson-gxl"; model = "Phicomm N1"; cvbs-c
  4. Hello everyone, this is my first post. I extracted 6 x96-max and x96-max + dts from the Android box, but I do n’t seem to have permission to upload attachments. I do n’t know how to upload? I have one x96-max and one x96-max +, both of which have 4G memory and 64G EMMC. Both WIFI modules are 6222B-SRB, based on RTL8822BS, so they can not work in armbian. In addition, the x96-max + Ethernet uses meson-sm1-sei610.dts for minor modifications. The Ethernet card cannot work at Gigabit, but it can work at 100M. total 1056 -rw-r--r-- 1 root root 77824 Feb 28 22:44 01_dtbdump_Amlogic.dtb
