The spl command is used to export a boot parameter image to RAM. Later
|
||||
it may implement more functions connected to the SPL.
|
||||
|
||||
SUBCOMMAND EXPORT
|
||||
To execute the command everything has to be in place as if bootm should be
|
||||
used. (kernel image, initrd-image, fdt-image etc.)
|
||||
|
||||
export has two subcommands:
|
||||
atags: exports the ATAGS
|
||||
fdt: exports the FDT
|
||||
|
||||
Call is:
|
||||
spl export <ftd|atags> [kernel_addr] [initrd_addr] [fdt_addr if fdt]
|
||||
|
||||
|
||||
TYPICAL CALL
|
||||
|
||||
on OMAP3:
|
||||
nandecc hw
|
||||
nand read 0x82000000 0x280000 0x400000 /* Read kernel image from NAND*/
|
||||
spl export atags /* export ATAGS */
|
||||
nand erase 0x680000 0x20000 /* erase - one page */
|
||||
nand write 0x80000100 0x680000 0x20000 /* write the image - one page */
|
||||
|
||||
call with FDT:
|
||||
nandecc hw
|
||||
nand read 0x82000000 0x280000 0x400000 /* Read kernel image from NAND*/
|
||||
tftpboot 0x80000100 devkit8000.dtb /* Read fdt */
|
||||
spl export fdt 0x82000000 - 0x80000100 /* export FDT */
|
||||
nand erase 0x680000 0x20000 /* erase - one page */
|
||||
nand write <adress shown by spl export> 0x680000 0x20000
