| 80 | 3. Flash U-Boot |
| 81 | --------------- |
| 82 | The flash range 0xFF800000 to 0xFFFFFFFF can be divided into 2 halves. |
| 83 | It is possible to use either half to boot using u-boot. Switch 5 bit 2 |
| 84 | is used for this purpose. |
| 85 | |
| 86 | 0xFF800000 to 0xFFBFFFFF - 4MB |
| 87 | 0xFFC00000 to 0xFFFFFFFF - 4MB |
| 88 | When this bit is 0, U-Boot is at 0xFFF00000. |
| 89 | When this bit is 1, U-Boot is at 0xFFB00000. |
| 90 | |
| 91 | Use the above mentioned flash commands to program the other half, and |
| 92 | use switch 5, bit 2 to alternate between the halves. Note: The booting |
| 93 | version of U-Boot will always be at 0xFFF00000. |
| 94 | |
| 95 | To Flash U-Boot into the booting bank (0xFFC00000 - 0xFFFFFFFF): |
| 96 | |
| 97 | tftp 1000000 u-boot.bin |
| 98 | protect off all |
| 99 | erase fff00000 ffffffff |
| 100 | cp.b 1000000 fff00100 80000 |
| 101 | |
| 102 | To Flash U-boot into the alternative bank (0xFF800000 - 0xFFBFFFFF): |
| 103 | |
| 104 | tftp 1000000 u-boot.bin |
| 105 | erase ffb00000 ffbfffff |
| 106 | cp.b 1000000 ffb00100 80000 |
