Boot Logo not changed

Hello,

I have tried to change my boot logo. I followed this tutorial

as well as the following forum entry

So I created a new bmp.blob and this worked without an error. The command I used is the following

OUT=$PWD ./genbmpblob_L4T.sh t210 ./config_file ./BMP_generator_L4T.py /usr/bin/lz4c bmp.blob

The messages while running this command are uploaded.
[genbmpblob_L4T.sh messages|attachment](upload://pvqS4HWhFnntbbwGeHs7X9S0dcm.sh message) (537 Bytes)

Then I copied the blob to “/Linux_for_Tegra/bootloader/bmp.blob”

I want to create a complete new image so I went ahead and used the jetson-disk-image-creator.sh in “/Linux-for-Tegra/tools”. The command I used was the following

sudo ./jetson-disk-image-creator.sh -o sd-blob.img -b jetson-nano-2gb-devkit

I can flash a new SD card with this image. The boot logo is still the nvidia logo.
Am I doing something wrong?
The jetson-disk-image-creator.sh is writing the bmp.blob as far as I can see

I also upload all messages of the jetson-disk-image-creator.sh
jetson-disk-image-creator messages (14.0 KB)

Can someone give me a hint what I am missing?
Thank you very much in advance!

I think we should clarify few things for you to understand how this work.

  1. The BMP blob is stored inside a partition “BMP”. During the boot up, cboot will load out the logo from this partition.

  2. The BMP partition on rel-32.5.1 is not located on your sdcard, it is located on the QSPI on the jetson nano module. Thus, the method to update it is using the flash.sh to flash the board. Creating a new sdcard image does not help.
