Boot/Splash logo change

[Moud_Sanchez]

Hey guys,

Can someone point me in the right direction on how to the OGA boot/splash screen?
Replace the image in SPI Flash?

See the flash layout here: https://wiki.odroid.com/odroid_go_advan ... ery_spirom
Try extracting the hardkernel logo.gz with dd. Get file properties with mediainfo to see resolution + bit depth. Create your own bmp, gzip it, check the size (so it fits in its slot) and flash it with dd.

Hi.
If you want to change only booting LOGO image, you don't need to update SPI flash,
but just copy a bmp image in vfat folder of SD card with name "logo.bmp".

In u-boot logic, a display driver finds (1) logo.bmp in vfat folder of SD card
and then, (2) read a logo section of SPI Flash if there is no available image in sd card.

Please note the image size should be 320x480 (portrait one) and bmp format.
Here is a reference sample, logo_hardkernel.bmp.

Thanks joy, I wasn't aware uboot was so flexible.

Hi @mad_ady,
Your guide is also available for OGA users who want to mount their LOGO image in SPI flash permanently.
I will make a wiki page this week including two methods.
Thanks!

[Moud_Sanchez]

Thanks guys!

I'll give it a shot when I get home

Hi @Joy, I just tried it and the image does appear but the OS doesn't load. I'm wondering if the issue is due to bmp specs.
W320 x H480
24bit

Also, I tried copying the sample bmp from: https://github.com/hardkernel/u-boot/tr ... hardkernel and get the same result.

This is where it hangs:

Hi @Moud_Sanchez,
I can reproduce the same issue with the latest OS image.
I will check it and fix it soon.
Could you wait for a couple of days?

So sorry for the inconvenience.

Hi @Joy, when you update the wiki, please include how to enable the standard linux boot messages -- as in the above picture. (I like having the HK logo on SPI boot. It's cool.) But Ubuntu splash hides important details. Removing the "quiet splash" from BOOT's boot.ini simply blanks the Ubuntu startup logo still no messages. In most linux distros, that would stop suppressing boot messages.

Thanks in advance. MG

Hi @maker_gamer,
OK. I see well.
I will add the section in a new wiki page.
Thank you for the valuable comment.

Please note that the Kernel boot log display may slow down the booting time a couple of seconds.

Try to put this file in /boot and post the results.

The messages displayed appears to indicate an issue with the SD card since the root partition can not be mounted.

[Moud_Sanchez]

@joy - thank you for looking into it and anxious to try the result.

@Etx - it didn't work.

@crashoverride - I thought that too so I've tried multiple SDs on Stock, TheRA and Batocera - all behave the same. Also, please note that it boots up fine in all my SDs and builds without a logo.bmp in vfat.

[Etx]

Hmm, strange. Got this file from here.
Based on author's video, it's working fine.

[Moud_Sanchez]

Ya, saw that article before I created this post, I believe he modified the bootloader.

[joy]

@Moud_Sanchez,
So sorry for late update.
I was not available to look into this issue last week because of other jobs.

For this issue, I found a root cause.
After 'run bootcmd' of u-boot, display driver tries to parse drm parameters and load logo image again
and during this process with 'fatload', it looks ramdisk-related header gets modified abnormally.
https://github.com/hardkernel/u-boot/bl ... ay.c#L1433

Code: Select all

rootfs image is not initramfs (junk in compressed archive); looks like an initrd

Actually I still keep finding the exact address, but I made a patch that makes you load your custom logo image by adding fat folder.
Once I confirm this approach is best, it will be included for a next release.

Here is the u-boot patch.
I attached a diff file, too.
With this patch, you can use your custom logo by just adding "logo.bmp" into fat folder of your sd card.
BMP file format is same as I mentioned before and you used for previous test.

You need to build u-boot with this patch.
If you don't have build environment, I will provide binary files of boot loaders soon for your test.
(*** updated ***) I also attached a test boot loaders. "sd_fuse_20200226_logotest.zip".

Then, update boot loaders of SD card as following.

If you need another guide to update boot loader, please let me know.

Hi @joy, this is amazing - thank you for looking into it.

Unfortunately, I'm traveling for work until the end of March and don't have access to a build environment.

Also, it'll be awesome if you can provide another guide. I can study it while I'm away

Thank you!

Hi @Moud_Sanchez,
Thank you for the feedback.
I've attached pre-built boot loaders in my previous post, so you don't need to build u-boot, but just use the binaries.
Please find an attachment, "sd_fuse_20200226_logotest.zip".

And are you familiar with running 'dd' utility as described in this wiki page?
https://wiki.odroid.com/odroid_go_advan ... ur_sd_card
I will find another way to update u-boot of SD card.
Or anybody here who has idea to update u-boot without 'dd' unitlity?

Let me check if there is any plan for a next new image or other methods like using package update.

Hi @joy,

I only have my work laptop which is win10. I went ahead built an environment anyway - just don't tell my work

Your patch worked, thank you!
Hopefully it'll be added in the next release.

[mad_ady]

Hooray for abusing work laptops!

Hi @Moud_Sanchez,
Thank you for your confirmation and sharing the result.
That's a cool logo image!

Glad to hear it works.
This patch will be included in a next image.
