Otavio Salvadore186b182015-11-19 19:02:36 -0200[diff] [blame]463. Booting from the SD card
47---------------------------
48
49- Flash the SPL image into the SD card:
50
51sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
52
53- Flash the u-boot.img image into the SD card:
54
55sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
56
57- Insert the SD card into the big slot.
58
59The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
60the board from SPI first.
61
62It is also possible to boot from the SD card slot by using the 'bmode'
63command:
64
65=> bmode esdhc4
66
Bin Meng75574052016-02-05 19:30:11 -0800[diff] [blame]67And then the U-Boot from the big slot will boot.

Bin Meng75574052016-02-05 19:30:11 -0800[diff] [blame]69Note: If the "bmode" command is not available from your pre-installed U-Boot,
Otavio Salvadore186b182015-11-19 19:02:36 -0200[diff] [blame]70these instruction will produce the same effect:
