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

Re: [U-Boot] Splash screen problem
The environment variable preboot runs after splashimage, which other env variablecan I use, which runs before splashimage?

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 2500 in RAM, so you should define => setenv splashimage 2500 Of course the reading from NAND must be done somewhere else, for example as part of a "preboot" command.

"0" is obviously a bad address for this purpose - what exactly is your setting of the "splashimage" environment variable?

[U-Boot] Splash screen problem
Hello, i am new in uboot. I have already configured and compiled uboot (i am using version 2009.11), but i have problem with splash image. I am using AT91SAM9263 processor witch connected NAND flash and some RAM. I can save image to nand or read it back without problems, but i can't load image and show it to display. When I use and save "setenv splashimage 'nand read 2500 C 2'", during next boot shows me warning "Error: no valid bmp image at 0". How to solve this problem. Thanks for advice.
