Disable reading uEnv.txt in U-boot

Hello Srini,

If you unset the bootenv from the U-Boot stage

U-Boot# setenv bootenv
U-Boot# saveenv

loading the uEnv.txt will be skipped.

More boot time optimization techniques can be found on this page.
processors.wiki.ti.com/.../Boot_Time_Optimization

Best regards,
Kemal

Dear Kemal,

Many Thanks a lot that worked, but am seeing the below message ** Unable to read file uImage **, could you please let me know why this message is seen & how this can be avoided??

Many Thanks in advance

Could you attach the feedback from the printenv command?

U-Boot# printenv

Change the mmcboot:
from
mmcboot=mmc dev ${mmcdev}; if mmc rescan; then echo SD/MMC found on device ${mmcdev};if run loadbootenv; then echo Loaded environment from ${bootenv};run importbootenv;fi;if test -n $uenvcmd; then echo Running uenvcmd ...;run uenvcmd;fi;if run loadimage; then run mmcloados;fi;fi;
to
mmcboot=run mmcloados;

U-Boot# setenv mmcboot run mmcloados
U-Boot# saveenv

Keep in mind loading the environment variables from uEnv.txt on this device will no longer work.

Dear Kemal,

One more input from you how can I alone set only lpj using setenv

Ie., I tried setting using the command

setenv optargs lpj 3590144

But the above command is not working, could you please let me know how can I alone set only lpj using setenv

And also how can I fix only kloadaddr using setenv?

Kindly do the needful

Many thanks in advance

Since the lpj is a part of the bootargs. You must change the bootargs parameters.

U-Boot# setenv bootargs console=ttyO1,115200n8 ip=off lpj=3590144 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
U-Boot# saveenv

In same way you can fix the kloadaddr

U-Boot# setenv kloadaddr address
U-Boot# saveenv

Dear Kemal,

Thanks a lot for your inputs, could you please help me out with few more queries

1. In the kloadaddr should we mention the numerical value of the address or only  the word "address" is sufficient??

2. In Disabling the console output using "quiet" ie., if I use the below command, am unable to see the messages related to console 

setenv optargs quiet

But could you please let me know if I want to renable the console messages & if I want to disable the quiet, how this can be done, am asking this because today it got saved to EMMC by default (as usually I would set using fwsetenv in rootfs prompt, once after kernel & rootfs is up) & when I wanted console messages, I was unable to get it

3. Does the bootargs quiet & CONFIG_SILENT_CONSOLE 1 or setenv silent 1 are same??

4. I similar fashion, could you please let me know how to disable SPL & u-boot related console messages & how can I renable if it is required for time being using setenv

5. One of the links I found that remove -g option is also one of optimization techniques, but am unable to find & remove the "-DDEBUG" and/or "-DBGFLAGS" (-g) in config.mk file of u-boot or kernel (as am using ti sdk 8)

6. And one more input, how can I avoid saving all these bootargs to EMMC for  time being, because finally once everything is fine tuned & verified this can be saved to EMMC once for all, Is stopping in uboot & loading the images via NFS might be the only option to avoid saving to EMMC for ??

Kindly do the needful as early as possible

Many Thanks in advance

Dear Kemal,

Could you please provide any inputs w.r.t the above query

Thanks in advance

U-Boot# setenv kloadaddr 0x82000000
U-Boot# saveenv

#KBUILD_CFLAGS    += -g
#KBUILD_AFLAGS    += -g

Dear Kemal,

Many Thanks a lot for your detailed description, that really helped me lot

Two more inputs w.r.t boot time optimization,

1. Is ti possible for me to skip u-boot stage & load kernel ,
could you please provide me with detailed steps how this can be accomplished

2. Regarding the deffered Initialization, will the below command 

echo 1 >/proc/deferred_initcalls will revoke the loading of modules dynamically (similar to insmod or modprobe)

Is my understanding is correct??

Many Many Thanks a lot for your support & would appreciate the same

The detailed steps are here ti-sdk-am335x-evm-08.00.00.00/board-support/u-boot-2014.07-g7e537bf/board/ti/am335x/README and here ti-sdk-am335x-evm-08.00.00.00/board-support/u-boot-2014.07-g7e537bf/doc/README.falcon

Is my understanding is correct??

The deferred_initcalls will defer the init calls within the statically linked kernel modules. It is not designed to invoke module loading like insmod and modprobe.

Dear Kemal,

Many Many Thanks a lot for your detailed steps it would be really helpful for me & others as well

1. Am able to get shell prompt but CTRL-C is not working with the shell without using login prompt after doing the below changes

Amend the O0:12345:respawn:/sbin/getty 115200 ttyO0 line to O0:12345:respawn:/bin/login -f root ttyO0 </dev/ttyO0 >/dev/ttyO0 2>&1 to bypass the login prompt.

Could you please help me to get CTRL-C CTRL-Z CTRL-X to get working with the shell without using login prompt , beacuse am running an application where am unable to stop it using CTRL-C

Dear Kemal,

2. Am planning to reduce the rootfs size where I want to remove the unwanted libraries & binaries required for my application, could you please let me know where I can I get the information that this binary/library is for this purpose or any specific application or services?? if there is any document or link would be helpful, could you please provide me 

 3. I am planning to stop running udev, even i tried running udev in backgorund but it gave me few seconds improvement but if I remove udev, could you please let me know how hot-plug devices can be managed without udev , could you please let me know is there any hotpluggable scripts available for ethernet or USB which am uisng in this product,

I noticed if I remove udev, it gives me a bootup time of 8 sec other wise it is 17 sec

Kindly do the needful as early as possible

Many Thanks in advance

Dear Kemal,

Am really impressed with your support w.r.t all the threads

1. Any inputs w.r.t the CTRL-C getting working on shell prompt, I hope some modifications needs to be done in rc or rcS file could you please let me know how this can be done

2. I hope mdev is light weight process than udev, could you pls let em know how this can be cross_compiled & installed in arago-base rootfs,

or

am starting the system with udev enabled & make kind of a backup of the created device nodes. Now modify the init script like this: instead of running udev, copy the device nodes that I had jus made a backup inot /dev/ folder does this works, is this reliable?? could you please confirm or any harm in the future??

And now am planning to install hotplug-daemon, could you please let me know how this hotplug dameon can now be installed

I hope this udev is only now my major concern

Kindly do the needful as early as possible

Many Many Thanks in advance again

Dear Kemal,

Extremely sorry to push you hard,

Could you please provide any inputs wrt the above queries

Many Thanks in advance

Dear Kemal,

The below commands worked Kemal, Could you please let me know how this can be automated in uboot configuration file (ie., include/configs/am335x-evn_config)

$ setenv console null
$ savenv

Kindly do the needful as early as possible

Many Thanks in advance,

I tried the following but this is not working, could you please let me know am I missing anything wrong??

"console=null \0" \ in include/configs/am335x_evm.h  is this correct??

Do you get any warnings while rebuilding the u-boot?

I Hope I didn't get any warnings while rebuilding uboot

Could you please kindly retry from your end & please let me know
