Did you mean after you set uEnv.txt, but it doesn’t execute when board boot？
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
btw. here is my bootlog:

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

Maybe you miss “env import -t ${scriptaddr} ${filesize}”.
Did you check item10，will it run “env import -t ${scriptaddr} ${filesize}”？
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
@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
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.
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…
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…
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).

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:

Kernel with wifi-driver cannot be compiled with gcc7
what do you mean default entry?
entry what process?
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
Hello, frank, after I checked, I will post you.
hoping it works 
testing tomorrow, just for you to see how i mean (no need for param-moving over different functions)
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 try to change it back to 10 => works now as expected
