Boot Linux kernel with initramfs fails

Dear Wolfgang Denk,

I forgot some explanations, sorry about that.

I refer to this problem :
http://lists.denx.de/pipermail/u-boot/2013-July/159055.html

First, I tried to boot linux with initramfs through u-boot, but I had the same problem explained in my first post.

Here is a part of the config file used by my -boot :

/* High Level Configuration Options */
#define CONFIG_ARMV7 /* This is armv7 Cortex-A9 CPU core */
#define CONFIG_MXC
#define CONFIG_MX6DL
#define CONFIG_MX6DL_DDR3
#define CONFIG_MX6DL_SABRESD
#define CONFIG_DDR_32BIT
#define CONFIG_FLASH_HEADER
#define CONFIG_FLASH_HEADER_OFFSET 0x400
#define CONFIG_MX6_CLK32 32768

/* Disable secure boot feature in default, if you want to enable this
* feature, please carefully read related documents, you may needs to
* change u-boot.lds */
#undef CONFIG_SECURE_BOOT

#define CONFIG_SKIP_RELOCATE_UBOOT

#define CONFIG_ARCH_CPU_INIT
#undef CONFIG_ARCH_MMU /* disable MMU first */ #define CONFIG_L2_OFF /* disable L2 cache first*/

#define CONFIG_MX6_HCLK_FREQ 24000000

#define CONFIG_DISPLAY_CPUINFO
#define CONFIG_DISPLAY_BOARDINFO

#define CONFIG_SYS_64BIT_VSPRINTF

#define BOARD_LATE_INIT

#define CONFIG_CMDLINE_TAG /* enable passing of ATAGs */
#define CONFIG_SERIAL_TAG
#define CONFIG_REVISION_TAG
#define CONFIG_SETUP_MEMORY_TAGS
#define CONFIG_INITRD_TAG
#define CONFIG_MXC_GPIO

initramfs is loaded in ram at 0x10C00000 by mfgtools, which is the freescales's manufacturing tool.

I don't know which configuration I need to set on u-boot to tell him initramfs is at address 0x10C00000, and consequently it hands on linux.

I am really bloqued on this problem.
Can you give me some hints ?

Tanks a lot !

Dear Jean-Baptiste,

And there you wrote:

| When I boot Linux kernel with FIT Image, the kernel does not unpacking initramfs.
| ( The root cause is "initrd_start is NULL".)
| 
| The initramfs is built-in with kernel, so I don't specify ramdisk in my
| kernel.its file.

initramfs handling is internal to Linux. This is not a problem with U-Boot.

Check how you build your kernel image and make sure the initramfs image (and a working one) gets processed there.

Best regards,

Wolfgang Denk

Good morning. This is the telephone company. Due  to  repairs,  we're
giving  you  advance notice that your service will be cut off indefi-
nitely at ten o'clock. That's two minutes from now.

I'll try to have linux support so.

Thank you.
