I have tried to change kernel logo image as described in Splash Screen on the Linux Kernel | Toradex Developer Center
I could follow all of steps in the website. I have confirmed it by checking that there is a custom logo image file in ~/linux-toradex/drivers/video/logo/
However, after updating my OS image on the board. I have got following error message,
Openbox Syntax Error One or more XML errors were found while parsing the Openbox configuration files. See stdout for more information. The last error seen was in file "/home/root/.config/openbox/lxde-rc.xml" line 1, with message : Document is empty.
The possible reasons might be:
my custom logo resolution is 1920x720 which is not normal, but same size with display
When I made logo image, I found something different log like below.
$ ppmquant 224 logo-optimal_1920x720.ppm > logo_optimal_1920x720_224.ppm ppmquant: making histogram... ppmquant: 24124 colors found ppmquant: choosing 224 colors... ppmquant: mapping image to new colors...
$ ppmquant 224 toradexlogo_1024x600.ppm > toradexlogo_1024x600_224.ppm pnmcolormap: making histogram... pnmcolormap: Scanning image 0 pnmcolormap: 271527 colors so far pnmcolormap: 271527 colors found pnmcolormap: choosing 224 colors... pnmremap: 224 colors found in colormap
Thanks in advance!
