How to extend the uboot-menu

(Frank W.) #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


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

(Frank W.) #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

(ZB) #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.

(Frank W.) #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…

(Frank W.) #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…

(Frank W.) #26

here my logs from

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:

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

(Frank W.) #29

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


(ZB) #30

what do you mean default entry?

entry what process?

(Frank W.) #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:

	menu->active = 0;

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

(ZB) #32

Hello, frank, after I checked, I will post you.

(Frank W.) #33

hoping it works :slight_smile: testing tomorrow, just for you to see how i mean (no need for param-moving over different functions)

(Frank W.) #34

Basicly this works. I’ve set the env-var in uboot-console and run bootmenu. If i go again in console, change this var and run bootmenu again it is not recognized. In code it looks like bootmenu is created everytime it is shown so it should work everytime

mhm…last param of simple_strtol is “base”…here so decimal not the default value i thought :slight_smile: try to change it back to 10 => works now as expected :slight_smile:

(Frank W.) #35

@Jackzeng have you find a way to load uenv.txt before display menu?

(ZB) #36

hi, frank, I need some time, haha:grinning:
