1 1. SATA usage in U-boot
3 Two ways to operate the hard disk
5 * Raw read/write block from/to SATA hard disk;
6 * ext2load read file from ext2 filesytem in hard disk
8 1.0 How to know the information of SATA hard disk?
12 SATA device 0: Model: ST3320620AS Firm: 3.AAD Ser#: 4QF01ZTN
14 Supports 48-bit addressing
15 Capacity: 305245.3 MB = 298.0 GB (625142448 x 512)
17 1.1 How to save the kernel, filesystem, dtb to SATA hard disk with raw?
19 Notes: 0x1000 sectors = 2 MBytes
22 => tftp 40000 /tftpboot/uImage.837x
23 => sata write 40000 0 2000
26 => tftp 40000 /tftpboot/ramdisk.837x
27 => sata write 40000 2000 8000
30 => tftp 40000 /tftpboot/mpc837xemds.dtb
31 => sata write 40000 a000 1000
33 1.2 How to read the kernel, filesystem, dtb from SATA hard disk with raw?
36 => sata read 200000 0 2000
39 => sata read 1000000 2000 8000
42 => sata read 2000000 a000 1000
45 => bootm 200000 1000000 2000000
47 1.3 How to load image from ext2 filesystem in U-boot?
49 U-boot doesn't support ext2 write to hard disk, so
50 you have to write the image to hard disk under Linux env,
51 before you load image from ext2 filesystem.
