Hello guys,
thank you for writing back. As you said, I updated u-boot on my unit to
version 2009.08-cm-fx6-0.91+tools (Nov 19 2013). The issue remains the
same that I cannot boot an other u-boot from SD card which is what I
need to find out why the kernel is not booting properly.
First, let's talk about the u-boot SD card issue:

That is the output of the bootloader inside the SPI. It says:
Boot Device: SPI NOR
I believe that this should be "SD" card.
On the utilite forums, there is a thread where people have exactly the
same problem:

Why do I need to re-compile u-boot? Your version passes a board id to
the kernel and it appears that the kernel won't boot with the device
tree file that was passed to it.
Possibly, this can be solved by this change:
[root(a)hokey u-boot]# git diff
diff --git a/board/compulab/cm_fx6/cm_fx6.c b/board/compulab/cm_fx6/cm_fx6.c
index f46980d..91ffcdf 100644
--- a/board/compulab/cm_fx6/cm_fx6.c
+++ b/board/compulab/cm_fx6/cm_fx6.c
@@ -805,7 +805,7 @@ int board_init(void)
setup_boot_device();
/* board id for linux */
- gd->bd->bi_arch_number = MACH_TYPE_CM_FX6;
+ //gd->bd->bi_arch_number = MACH_TYPE_CM_FX6;
/* address of boot parameters */
gd->bd->bi_boot_params = PHYS_SDRAM_1 + 0x100;
But as long as I cannot test it am not too sure about how the kernel
behaves.
So, please can you look into this and find out if there is a way to get
my device booting u-boot from SD card?
