| 47 | 1.3 How to load image from ext2 filesystem in U-boot? | |
| 48 | ||
| 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. | |
| 52 | ||
| 53 | => ext2ls sata 0:1 / | |
