Boot logo personalizzation 2

[zccfba]

My question is this:
Why is an address different from the one indicated in the "README.md" file indicated in the files that I find in the distribution?
I used 1024x600 resolution images for my tests.
Currently my script for generating the "logo" file on a SOM - SSD202D is this:
#! / bin / sh
rm -rf logo
./dispcfggen -c -o logo -p 0x07C00000 -s 0x00300000 -d CC0702I50R
./logogen -a -i ./image/tti-logo1024_600.jpg -o logo
./logogen -a -i ./image/tti-upgrade1024_600.jpg -o logo

Do you think this could be correct, given that, between the "README.md" file with the instructions and the files already present in the folder, there are inconsistencies in the address values ​​passed to the dispcfggen file?

Right now the result of the file replacement is a green screen instead of the correct logo appearing.
