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: 2

i 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.

Probably they came from UEFI's removable media support, specifically commit c606c0059f7f Author: Masahisa Kojima masahisa.kojima@linaro.org Date: Thu Apr 28 17:09:42 2022 +0900

bootmenu: add UEFI boot entry into bootmenu

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.

Try to disable either CONFIG_CMD_EFICONFIG or CONFIG_CMD_BOOTEFI_BOOTMGR, even CONFIG_EFI_LOADER if you don't need UEFI subsystem at all.

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
