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
|
||
|
|
---------------------------------
|
||
|
|
|
||
|
|
This version of u-boot works only on the 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.
