Change U-boot args

[AndreiCherniaev]

Hello

I rebuild U-boot for my Orange pi 4B. I want disable debug uart. As I see in file boot-rockchip64.cmd I shouldn't change anything. I need /boot/orangepiEnv.txt But I can't find it in my build tree. @orangepi-xunlong are you shure that /boot/orangepiEnv.txt exist for Orange Pi 4B?

[orangepi-xunlong]

Each platform has a slightly different version of orangepiEnv.txt. Here is the RK3399:

https://github.com/orangepi-xunlong/orangepi-build/blob/main/external/config/bootenv/rockchip.txt

It will be copied at compile time as /boot/orangepiEnv.txt

How I was understand that orangepi-build/external/config/bootenv/rockchip.txt is orangepiEnv.txt for my Orange Pi 4B? How I can guess name for another SBC like Orange Pi 4g or Orange Pi PC PLUS?

Where I can get full list of options? For example I want disable debug uart for my Orange Pi 4B, what string should I write to rockchip.txt?

P.S. /home/a/Documents/orangepi-build/external/config/sources/README.md and /home/a/Documents/orangepi-build/external/config/sources/families/README.md is it really readme or a joke?

I try new Ubuntu18 img from googledrive for Orange Pi 4B. There is no more ttyS4, but there is ttyS0 and ttyFIQ0. But as I understand tty0 (means UART0) is part of bluetooth module, isn't in @orangepi-xunlong ?
I also try build Ubuntu 18 from orangepi-build. It has got the same problem. UART0 is not in 40 pins GPIO so I can't use it... I also look at OrangePi RK3399... In OrangePi RK3399 there is UART2 for debug and there is UART0 on 40 pins GPIO. So looks like @orangepi-xunlong using dts file of OrangePi RK3399 for Orange Pi 4B.

P.S. In old Ubuntu18 there is ttyS4.
P.S.S. My dream is to disable debug UART (ttyFIQ0) to use it in my application. How I can do it?

Yes, you are right!

UART4 and SPI1 are multiplexed. By default, SPI1 is turned on and UART4 is turned off. You can turn off SPI1 and turn on UART4 in DTS, so that UART4 in 40PIN can be used.

This is the procedure in the Chinese manual. I believe you can understand it. Good luck!

1. There is no ... dts/rockchiprk3399-orangepi-common.dts

May be you are talking about rk3399-orangepi-common.dtsi? There are two rk3399-orangepi-common.dtsi:
in boot/dts/rockchip
and in /scripts/dts/include-prefix/arm64/rockchip
what item I need?

2. Why I can't edit u-boot/v2020.04-rockchip64/u-boot.cfg? After every make u-boot (compilation.sh) file u-boot.cfg will regenerating, all my changes will erased! For example I want do
   #define CONFIG_CMD_CONSOLE 0
   How?

1. There is **no** ... dts/rockchiprk3399-orangepi-common.dts

May be you are talking about rk3399-orangepi-common.dtsi? There are two rk3399-orangepi-common.dtsi:

Sorry, it should be rk3399-orangepi-common.dtsi.

1. Why I can't edit u-boot/v2020.04-rockchip64/u-boot.cfg? After every make u-boot (compilation.sh) file u-boot.cfg will regenerating, all my changes will erased! For example I want do
   #define CONFIG_CMD_CONSOLE **0**
   How?

U-boot.cfg is automatically generated and you should modify configs/orangepi-4-rk3399_defconfig, for example:

--- a/configs/orangepi-4-rk3399_defconfig
+++ b/configs/orangepi-4-rk3399_defconfig
@@ -11,6 +11,7 @@ CONFIG_DEBUG_UART=y
 CONFIG_DEFAULT_FDT_FILE="rockchip/rk3399-orangepi-4.dtb"
 CONFIG_MISC_INIT_R=y
 # CONFIG_DISPLAY_CPUINFO is not set
+# CONFIG_CMD_CONSOLE is not set
 CONFIG_DISPLAY_BOARDINFO_LATE=y
 # CONFIG_SPL_RAW_IMAGE_SUPPORT is not set
 CONFIG_SPL_STACK_R=y

And remember to set IGNORE_UPDATES="yes" in userpatches/config-default.conf so that the source code will not be updated with each compilation.
