| 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 <fdt|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 |
