[U-Boot] Fwd: Re: 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 !

The same problem as what or who? I cannot even guess...
I have some trouble booting linux kernel with initramfs. I built linux kernel with CONFIG_BLK_DEV_INITRD, so Kbuild generates usr/initramfs_data.cpio which is integrated into the kernel.
... ...
My kernel hangs after the last line, instead of doing "Freeing init memory: ..." but I don't know if it comes from the same problem or not...
Sorry, but I cannot see anything in your posting which might even remotely be related to U-Boot. This is the U-Boot mailing list - your question is off topic here.
Best regards,
Wolfgang Denk

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.

I'll try to have linux support so.
Thank you.
