I wanted to know if the procedure described in the README file is correct, because it seems that in the files used to create the "logo" file the addresses seem to be exchanged. How should the script be configured to work properly? The script set up in this way does not work.

rm -rf logo ./dispcfggen -c -o logo -p 0x07C00000 -s 0x00300000 -d CC0702I50R

./dispcfggen -c -o logo -p 0x03300000 -s 0x00300000 -d CC0702I50R

logo res:1024x600

./logogen -a -i ./image/tti-logo.jpg -o logo

logo res:1024x600

./logogen -a -i ./image/tti-upgrade.jpg -o logo

./logogen -a -i ./image/upgrade.jpg -o logo

thank you in advance. VirtualBox_Ubuntu_18_4_05_Bionic_Beaver_29_04_2021_11_05_21

If you are using our 1024*600 developing board,please check your chip version which was silky printed on the chip and chooce the correct memory address offset designed for SSD201 or SSD202.

https://github.com/wireless-tag-com/openwrt-ssd20x/wiki/LOGO wt-logo.jpg must have right size（LCD）, if LCD is 1024600，wt-logo.jpg must 1024600 FRD720X720BK is LCD name

product + LCD please see readme.md

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. IMG_20210513_085602

Second question: Where can I find a procedure to change the SOM display control and control MIPI displays at different resolutions?

Thanks in advance best regards
