Hi, i was able to create a seemingly correct patch file, by following this small tutorial: https://medium.com/coinmonks/make-linux-kernel-better-beginners-guide-to-writing-your-first-linux-patch-1125e4891e0d. What i did, was cloning the git mainline kernel repo and i updated the file arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi to my needs, which was just the change of line 17: stdout-path = "serial4:1500000n8"; afterwards i created the patch file by committing my change to my local repo and this command: git format-patch master..name-of-my-branch This gave my this file: From af079115d70a778d457d0067375dde81928fb4db Mon Sep 17 00:00:00 2001 From: = <...> Date: Tue, 30 Aug 2022 12:34:14 +0000 Subject: [PATCH] changed serial console port from 2 to 4 to omit issues with gpio sensors --- arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi b/arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi index 401e1ae9d944..b4c7ea9a93a1 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4.dtsi @@ -17,7 +17,7 @@ aliases { }; chosen { - stdout-path = "serial2:1500000n8"; + stdout-path = "serial4:1500000n8"; }; clkin_gmac: external-gmac-clock { -- 2.34.1 I have placed this file in the following folder userpatches/u-boot/u-boot-rockchip64/rk3399-change-serial-console-port.patch In addition to that i modified my config-default.conf and added the following build options: # additions to compile for the rock-pi4 CREATE_PATCHES="yes" BOARD="rockpi-4b" BRANCH="current" RELEASE="bullseye" PROGRESS_LOG_TO_FILE="yes" OFFLINE_WORK="no" USE_MAINLINE_GOOGLE_MIRROR="yes" # i had issues to pull from the original repo USE_GITHUB_UBOOT_MIRROR="yes" # same as above After running the compile.sh script i get the following message: [ o.k. ] Started patching process for [ u-boot rockchip64-rockpi-4b-current ] [ o.k. ] Looking for user patches in [ userpatches/u-boot/u-boot-rockchip64 ] [ o.k. ] * [l][c] add-board-clockworkpi-a06.patch ...

Hi, i'm currently trying to disable the serial console on port 2 on my Rockchip based Rockpi 4B (based on rk3399). I already found the following forum thread, that describes in brief, that i basically have to recompile my own armbian image. But still I'm missing some information. I have read the docs in docs.armbian.com and watched the YouTube video on how to build an armbian image. So far, i was able to setup a VM for building an image on my workstation. I also had a successful compile run yesterday, that created some output in my output folder. Now, I'd like to apply a patch, that changes the serial debugging console during boot from port 2 to port 4. I have created a patchfile using the source code files from the mainline linux repository with the following command: ``` diff -Naur rk3399-rock-pi-4.dtsi rk3399-rock-pi-4.dtsi.1 > rk3399-rock-pi-4.dtsi.patch ``` My patch file looks like this now: --- rk3399-rock-pi-4.dtsi 2022-08-29 12:33:21.534325708 +0000 +++ rk3399-rock-pi-4.dtsi.1 2022-08-29 12:36:59.535513608 +0000 @@ -17,7 +17,7 @@ }; chosen { - stdout-path = "serial2:1500000n8"; + stdout-path = "serial4:1500000n8"; }; clkin_gmac: external-gmac-clock { The original file is from here. My question(s) would be: - is this the correct way to create the patch file? - Where do i put the patch file (and how do i name it)?
