| SARTRE Leo | 2ea4de5 | 2013-06-20 15:46:50 +0200 | [diff] [blame] | 10 | By default, the Congatec board can boot only from the SPI-NOR. |
| SARTRE Leo | dce7176 | 2013-06-03 23:30:36 +0000 | [diff] [blame] | 11 | But, with the u-boot version provided with the board you can write boot |
| 12 | registers to force the board to reboot and boot from the SD slot. If |
| 13 | "bmode" command is not available from your pre-installed u-boot, these |
| 14 | instruction will produce the same effect: |
| 15 | |
| 16 | conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850 |
| 17 | conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000 |
| 18 | conga-QMX6 U-Boot > reset |
| 19 | resetting ... |
| 20 | |
| 21 | The the board will reboot and, if you have written your SD correctly |
| 22 | the board will use u-boot that live into the SD |
| 23 | |
| 24 | To copy the resulting u-boot.imx to the SD card: |
| 25 | |
| 26 | dd if=u-boot.imx of=/dev/xxx bs=512 seek=2 |
| 27 | |
| 28 | Note: Replace xxx with the device representing the SD card in your system. |
