Hi
I tried to find out why distroboot is enabled (i have not set it in my defconfig) and i think this is why:
│ Symbol: DISTRO_DEFAULTS [=y] │ │ Type : bool │ │ Prompt: Select defaults suitable for booting general purpose Linux dist │ │ Location: │ │ (3) -> Boot options │ │ Defined at boot/Kconfig:833 │ │ Selects: BOOT_DEFAULTS [=y] && AUTO_COMPLETE [=y] && CMDLINE_EDITING │ │ Implied by [y]: │ │ - ARCH_ROCKCHIP [=y] && <choice> && !ROCKCHIP_RK3399 [=n]
as far as i see you've got a response from Jonas about this option and he changed Kconfig file to BOOTSTD_DEFAULTS
as i have not used BOOTSTD_DEFAULTS before, what needs to be changed to have it working?
Please update to latest master branch, rk356x is not fully working with v2023.04 or earlier, especially BOOTSTD without extra CONFIGs.
With latest master branch CONFIG_BOOTSTD_DEFAULTS=y should be set by default for all ARCH_ROCKCHIP. And should work very similar to if you used to have "run distro_bootcmd" as your bootcmd.
It is still unclear what script/bootcmd you are trying to use, or if you used to have "run distro_bootcmd" as a fallback. Replacing "run distro_bootcmd" with "bootflow scan -lb" or "bootflow scan" could work as such fallback option.
basicly my Plan is to script the bootup via env in script with a bootmenu (default entry + additional ones which can be changed by an env.txt file), but i do not want to break existing setups (using extlinux/*.conf behaviour) and no additional bootmenu-entries.
The "distro" bootmeth described at the documentation you linked to will looks for a file called extlinux/extlinux.conf.
Is there a special reason why you need to use a custom bootmenu script and are moving from distro-boot (extlinux-config files)?
is there any documentation describing the "Standard boot"?
i found this, but it looks like the "old" distro-boot...or is is same from users PoV?
https://u-boot.readthedocs.io/en/latest/develop/bootstd.html
This is the documentation for standard boot.
I recommend you try out the commands bootdev, bootflow and bootmeth with CONFIG_BOOTSTD_FULL=y to get a better handling on how it would work on your device and how you can use them in your script.
Regards, Jonas
regards Frank

Maybe you have an idea because your patch removes distro-boot

For missing linebreak for autoboot this seems to be a calculation issue
https://source.denx.de/u-boot/u-boot/-/blob/master/common/menu.c#L439
Are you able to fix it with a patch?
Have not yet figured out which part of u-boot creates the mmc-entries on top of my bootmenu (i guess this comes from my still enabled distroboot options).
For missing linebreak i guess position calculation is wrong in this case.
Or if not, do you have a patch for the 'move to env-based bootmenu' so I can try it?
I have i builtin env file (uEnv_r2pro.txt) in my tree here and add (enable pepared option) the config-option to use this env file in topmost commit.

I had this in but disabled but this overrides the env created by distroboot-defines...but now enabling it to get rid of distroboot.

Hi,
i try to move from distro-boot (extlinux-config files) to an env-based bootmenu (builtin-environment) for my bananapi r2pro.
basicly it works, but i see more bootmenu-entries than i have defined in my environment
*** U-Boot Boot Menu ***
1. Boot from SD/EMMC. mmc 1:2 mmc 1:3 mmc 1:4 U-Boot consoleHit any key to stop autoboot: 2i have only defined one botmenu-entry (first one in uEnv_r2pro.txt)
bootmenu_0=1. Boot from SD/EMMC.=run newboot bootmenu_default=0
i guess the 3 mmc 1:x entries are part from distro-boot. i see a series from simon where he drops distroboot for rockchip-boards.
https://patchwork.ozlabs.org/project/uboot/patch/20230409084454.v9.8.I4cf770...
can anyone explain me where i can disable the mmc 1:x entries? i wanted to leave distro_boot as fallback but it seems this is not possible.
maybe i have to disable these?
BOOTMETH_DISTRO [=y] DISTRO_DEFAULTS [=y]
can i keep distro-boot (seems to works with env too, but overridden by my builtin env) somehow and drop the mmc-entries from my bootmenu?
any idea why i have no linebreak after u-Boot console?
i use u-boot 2023.04 my source for this conversion/tests is there: https://github.com/frank-w/u-boot/tree/2023-04-bpi-r2pro using modified configs/evb-rk3568_defconfig
