| U-Boot for the Congatec Conga-QEVAl Evaluation Carrier board with |
| qmx6 quad module. |
| |
| This file contains information for the port of U-Boot to the Congatec |
| Conga-QEVAl Evaluation Carrier board with qmx6 quad module. |
| |
| 1. Boot source, boot from SD card |
| --------------------------------- |
| |
| By default, the Congatec board can boot only from the SPI-NOR. |
| But, with the u-boot version provided with the board you can write boot |
| registers to force the board to reboot and boot from the SD slot. If |
| "bmode" command is not available from your pre-installed u-boot, these |
| instruction will produce the same effect: |
| |
| conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850 |
| conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000 |
| conga-QMX6 U-Boot > reset |
| resetting ... |
| |
| The the board will reboot and, if you have written your SD correctly |
| the board will use u-boot that live into the SD |
| |
| To copy the resulting u-boot.imx to the SD card: |
| |
| dd if=u-boot.imx of=/dev/xxx bs=512 seek=2 |
| |
| Note: Replace xxx with the device representing the SD card in your system. |
