The following are examples of critical environment variables.
7.19.3 NANDboot
COMX-P4080 has a U-Boot variable called "nandboot".
nandboot=setenv bootargs root=/dev/$jffs2nand rw
console=$consoledev,$baudrate rootfstype=jffs2 $hwbootargs
$othbootargs;bootm $norbootaddr - $norfdtaddr
The "nandboot" will load Linux kernel and DTB from NOR flash into RAM and then boot. JFFS2
will then mount on the file system on NAND flash as rootfs.
The following are the critical environment variables for "nandboot".
Below are examples of critical environment variables:
7.19.4 NFSboot
COMX-P4080 has a U-Boot variable called "nfsboot".
=> setenv norfsaddr E9000000
=> setenv norbootaddr EE000000
=> setenv norfdtaddr EFD00000
jffs2nand - MTD device for JFFS2 rootfs on NAND FLASH
norbootaddr - Linux kernel address on NOR FLASH
norfdtaddr - DTB address on NOR FLASH
=> setenv jffs2nand mtdblock7
=> setenv norbootaddr EE000000
=> setenv norfdtaddr EFD00000
