embedded linux change penguin logo
I want to change the penguin logo appearing at the startup. After search through I found this command,
pngtopnm nelogo.png | ppmquant -fs223| pnmtoplainpnm > logo_linux_clut224.ppm
But when I run I got an error message as follow.
unrecognized option `-fs223'
pnmtoplainpnm: EOF / read error reading magic number
can someone help me?
