| Writing U-Boot to NAND |
| ---------------------- |
| |
| To get the board into NVIDIA's recovery mode where you can write the firmware |
| you hold the force recovery switch (f.r.) while resetting or powering on. The |
| recovery, reset and power buttons are available on the side of the board |
| oposite the HDMI connector. They are also available on the satellite board. |
| |
| Make sure there are no USB devices attached to the board while using recovery |
| mode. One of the host side USB ports is reclaimed for the OTG port. |
| |
| The Seaboard has a number of boot jumpers that need to be correctly configured |
| to write to the NAND and boot from it. They are all located in the corner of |
| the board that has the Camera and LVDS connectors. |
| |
| The jumpers must be set as specified below before writing to the NAND. |
| |
| BOOT SEL 0 : jumper pins 2 and 3 |
| BOOT SEL 1 : jumper pins 2 and 3 |
| BOOT SEL 2 : jumper pins 1 and 2 |
| BOOT SEL 3 : jumper pins 1 and 2 |
| MFG MODE : jumper pins 1 and 2 |
| |
| These jumpers are also available on the keyboard. |
| |
| Once in recovery mode run the following from inside the chroot: |
