How to extend the uboot-menu

#13

Hello Frank-w,

uboot is also much code if you don’t know where to begin search ;(

I think the file you are looking for is u-boot-mt/include/configs/mt7623_evb.h. On line 445 the U-Boot Environment is defined. If you add your 2 new menu lines there and recompile u-boot it should work.

#define ENV_BOOT_MENU \
    "bootmenu_0=1. System Load Linux to SDRAM via TFTP.=run boot0\0" \
    "bootmenu_1=2. System Load Linux Kernel then write to Flash via TFTP.=run boot1\0" \
    "bootmenu_2=3. Boot Linux from SD.=run boot10\0" \
    "bootmenu_3=4. System Load Boot Loader then write to Flash via TFTP.=run boot3\0" \
    "bootmenu_4=5. System Load Linux Kernel then write to Flash via Serial.=run boot4\0" \
    "bootmenu_5=6. System Load Boot Loader then write to Flash via Serial.=run boot5\0" \
    "bootmenu_6=7. Boot system code via Flash.=run boot2\0" \
    "bpiver=1\0" \
    "bpi=bananapi\0" \
    "board=bpi-r2\0" \

    "scriptaddr=0x83000000\0" \
    "device=mmc\0" \
    "partition=1:1\0" \
    "kernel=uImage\0" \

    "checksd=fatinfo ${device} 1:1\0" \
    "loadbootenv=fatload ${device} ${partition} ${scriptaddr} ${bpi}/${board}/${service}/${bootenv} || fatload ${device} ${partition} ${scriptaddr} ${bootenv}\0" \
    "boot_normal=if run checksd; then echo Boot from SD ; setenv partition 1:1; else echo Boot from eMMC ; mmc init 0 ; setenv partition 0:1 ; fi; if run loadbootenv; then echo Loaded environment from ${bootenv}; env import -t ${scriptaddr} ${filesize}; fi; run uenvcmd; fatload mmc 0:1 ${loadaddr} ${bpi}/${board}/${service}/${kernel}; bootm\0" \

I will try that, in my case it will help.

but that solves not the problem with not loading environment from uEnv.txt before displaying menu.So uboot is not really configurable without recompilation/reinstall

#15

Basicly it works…i try to optimize vars and then push it to my repo

#16

optimizing vars seems not to work…here is what i tried:

"bootmenu_9=10. Boot Kernel 4.16.=run boot416\0" \
"boot416=run newloadenv; setenv kernel ${kernel416}; run newboot\0" \
"kernel416=uImage_4.16\0" \
"newloadenv=mmc init; if run checksd; then echo Boot from SD ; setenv partition 1:1; else echo Boot from eMMC ; mmc init 0 ; setenv partition 0:1 ; fi; if run loadbootenv; then echo Loaded environment  from ${bootenv}; env import -t ${scriptaddr} ${filesize}; fi; run uenvcmd\0" \
"newboot=fatload mmc ${partition} ${loadaddr} ${bpi}/${board}/${service}/${kernel}; bootm\0" \

the steps should be

  • load environment from uEnv.txt
  • set var “kernel” to the content of env-var kernel416
  • boot with new “kernel” var

instead the old kernel-var (kernel=uImage) is used (overwrite it seems not to work, also build-in content is not used)

any idea?

#17

Did you mean after you set uEnv.txt, but it doesn’t execute when board boot？

#18

i modified uEnv.txt, but it is not loaded in my construct for kernel 4.16 or at least my var-setting does not work

Boot fails with self-build u-boot

btw. here is my bootlog:

Starting kernel ...

i modified boot416 like this:

"boot416=run newloadenv; setenv kernel ${kernel416}; printenv; run newboot\0" \

i choose “10. kernel 4.16” but default uImage is loaded…printenv is also not executed

really strange behaviour…

making the steps manually:

Maybe you miss “env import -t ${scriptaddr} ${filesize}”.

Did you check item10，will it run “env import -t ${scriptaddr} ${filesize}”？

#21

newloadenv contains the “env import …”, but had some tests without the “run uenvcmd” and the checksd-part there, seems to work, but have to do some more tests

see https://github.com/frank-w/BPI-R2-4.4/commit/200b8f358a9ad087ac929ba5be60b280abefe04e

but anyway it will be nice if environment is loaded before menu is displayed so uboot can be controlled via uEnv.txt without modifying the code and permanently flash it

#22

@Jackzeng have you looked into it to load uenv.txt before displaying menu?

it is very annoying to patch uboot or using the uboot-console when switching between kernels

#23

Hello, frank, I have looked it before but not deeply, so what do you mean annoying when switching kernels? I probably could work this with you lately.

#24

i have multiple kernels installed in my system and patched uboot to have multiple entries, see commit posted above my last posting.

now i switching between 2 4.16-kernels (wlan/hdmi)… one defined by using kernel-directive (default entry), one using my kernel416-entry

it would be nice setting the names of bootmenu entries via uEnv.txt, so i have not to reflash uboot when doing these things…

any chance getting a newer uboot to work? maybe with hdmi-support? current uboot give only a purple screen…

#25

tried to modify it again…seems i bricked my card…(same with my current github-state)

this seems to be a compile-issue…multiple compilations in ubuntu 18.4 (gcc6) failed to boot…compiling in 14.4 works on the first try…

[BPI-R2] How to build an Ubuntu/Debian SD image from scratch
#26

here my logs from build.sh

build_14-4.log (13,7 KB) build_18-4.log (18,6 KB)

in ubuntu 14.4 it works with gcc 4.8.4

in ubuntu 18.4 it does not work…gcc ist 7.3 and arm-linux-gnueabihf-gcc is set to /usr/bin/arm-linux-gnueabihf-gcc-5

i do not work if crosscompiler is really used for uboot…i think it should be

:~$ update-alternatives --config arm-linux-gnueabihf-gcc
There are 2 choices for the alternative arm-linux-gnueabihf-gcc (providing /usr/bin/arm-linux-gnueabihf-gcc).

  Selection    Path                                Priority   Status

  2            /usr/bin/arm-linux-gnueabihf-gcc-7   50        manual mode

i tried to make a manual diff (automatic shows to much differences due to different message formats): diff.txt (5,3 KB)

any idea why uboot compiled in 18.4 fails to boot? @garywang

my uboot-menu looks now like this:

     1. Reload Bootmenu.
     2. Load Environment.
     3. Boot Linux from SD.

Uboot does not work if i compile it in ubuntu 18.4 using linaeo gcc arm-gnueabihf 5.5. Any idea why?

Kernel with wifi-driver cannot be compiled with gcc7

#29

is it possible to set the default entry via an environment-variable from uEnv.txt?

@Jackzeng

#30

what do you mean default entry?

entry what process?

#31

the numer that is selected in the bootmenu…currently it is always the 3rd

imho in code it is done via a const:

but imho there should be a way to set this via uenv.txt

maybe we can modify this to use a env-variable:

currently i don’t know how to access env-vars here, bit the code should look like this:

#if defined(CONFIG_MENU_ACTIVE_ENTRY)
	menu->active = CONFIG_MENU_ACTIVE_ENTRY;
#else
	menu->active = 0;
#endif
if (ENV_MENU_ACTIVE_ENTRY) {menu->active = ENV_MENU_ACTIVE_ENTRY;}

this seems to be the key:

i can add a new env-var like it’s done for bootmenu-delay…maybe i have to change the header of bootmenu_create and bootmenu_show to pass the new var like delay
