+This file contains information for the port of U-Boot to the Congatec +Conga-QEVAl Evaluation Carrier board.
+1. Boot source, boot from SD card +---------------------------------
+This version of u-boot works only on the SD card. By default, the +Congatec board boot from the SPI-NOR. +With the uboot version provided with the board you can write boot +registers to force the board to reboot and boot from the SD slot:
+conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850 +conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000 +conga-QMX6 U-Boot > reset +resetting ...
But is this not exactly the purpose of the "bmode" command ? Anyway, at next power-on, the board boots again from SPI-NOR. There should be indication here how to erase the SPI Flash
+The the board will reboot and, if you burnt your SD correctly the +board (see (2) for instructions) will use u-boot that live into the SD +card.
+2. Build +--------
+To build U-Boot for the Congatec board:
- make cgtqmx6_config
- make u-boot.imx
You do not need it. This is the general instruction to build any board in u-boot, and u-boot.imx is automatically generated for i.MX6 boards.
+To copy the resulting u-boot.imx to the SD card:
- sudo dd if=u-boot.imx of=/dev/sXx bs=512 seek=2&&sudo sync
+Note: Replace sXx with the device representing the SD card in your system.
This can be wrong if the Linux PC uses /dev/mmcblk* instead of /dev/sXx
