As with switching to a known panel, the settings take effect immediately upon completion of the command. This can be a very quick way to add support for a new display before committing it to the supported list.

Adding an entry into the lcd panels array in common/lcd panels.c will provide boot-time support.

7.1.5Saving settings to Flash EEPROM

All of the descriptions above are useful, but don’t address the issue of persis- tence. That is performed through the use of the ’panel’ environment variable and the ’saveenv’ Das U-Boot command.

The following example shows the process.

$set panel crt1024x768

$save

7.2Memory size configuration

The Neon￿R supports either 32 or 64MB of RAM.

Most of the default boot loader configuration assumes at least 32MB of RAM is available. In particular, the TEXT BASE variable in board/neon/config.mk links the uboot.bin image at 31MB from the start of RAM.
