Well, this cannot work.
As documented, "splashimage" is supposed to hold the address where the image is stored in memory.
The enviroment variable "splashimage" runs the command to read from NAND, but i don't know how to tell (return) to splashimage the address of bitmap after reading from NAND.
The command above reads the image to address 25000000 in RAM, so you should define
=> setenv splashimage 25000000
Of course the reading from NAND must be done somewhere else, for example as part of a "preboot" command.
Best regards,

The environment variable preboot runs after splashimage, which other env variablecan I use, which runs before splashimage?

You cannot. But you can fake the actions by using "nand read" and "bmp" as preboot command. Not perfect, but close.
