Hello L4 hackers.

I have two question (My question 1, 2 ). please  help me.

I'm trying to boot 'L4Linux + L4re + Fiasco' in Freescale i.MX6 Quad 
SABRE SD board (Cortex-A8, ARMv7-A).

Such as..

0. Get Source and install required package.

|$ cd /somedir/tudos
$ svn cat http://svn.tudos.org/repos/oc/tudos/trunk/repomgr | perl - init http://svn.tudos.org/repos/oc/tudos fiasco l4re l4linux_requirements|

1. L4 Re : configure and build (Success)

$ mkdir -p /path/to/obj/tudos
|$ make O=/path/to/obj/tudos oldconfig
$ make O=/path/to/obj/tudos -j2|


2. Fiasco : configure and build (Success)


||$ cd /somedir/tudos/src/kernel/fiasco
|$ make BUILDDIR=/path/to/obj/fiasco
$ cd /path/to/obj/fiasco
$ make menuconfig
$ make|

3. L4 linux : configure and build. (Failure)
(Here, i have trouble to build l4 linux after configure according to my 
board )


|$ cd /somedir/tudos
$ svn co http://svn.tudos.org/repos/oc/l4linux/trunk l4linux
$ cd l4linux
$ mkdir /path/to/obj/l4linux
$ make L4ARCH=arm CROSS_COMPILE=arm-linux- O=/path/to/obj/l4linux arm_defconfig
# In the menu, in "L4Linux configuration", set "L4 tree build directory" to /path/to/obj/tudos
$ make L4ARCH=arm CROSS_COMPILE=arm-linux- O=/path/to/obj/l4linux menuconfig

To configure according to my board(Freescale i.MX6q_sabre_sd), I was 
able to choice two kinds.

<The first >

|System type -> ARM system type (L4 Linux)
Build type (Use ARMv7)

<Result of the first >

1) Sucess build L4 linux and i got 'vmlinuz.arm'
2) 'make uImage' according to module.list

entry L4Linux_xs_2
kernel fiasco -nokdb
roottask moe rom/l4linux.cfg
module l4linux.cfg
module l4re
module ned
module vmlinuz.arm
module ramdisk-arm.rd|


3) i make SD Card bootable by u-boot.bin and bootstrap.uImage

4) Booting L4Linux + L4re + Fiasco in Freescale i.MX6q_sabre_sd

But, i have problem to boot it.

<My question 1.> Why hang at 'Starting kernel ...' ?

Setting environment variable and bootcmd , i have thought the setting is no problem.
This kernel image is wrong?

<The Second >

|System type ---> ARM system type (Allow multiple platforms to be selected)|
Multiple platform selection  ---> ARMv7 based platforms (Cortex-A, PJ4, Scorpion, Krait)
Build type
	Freescale i.MX family
	  Freescale i.MX support  ---> i.MX6 Quad/DualLite support

<Result of the second >

i could not build l4 linux because..

GEN     /path/to/obj/l4linux/Makefile
scripts/kconfig/conf --silentoldconfig Kconfig

ERROR: CONFIG_ARM_PATCH_PHYS_VIRT must not be enabled.

make[1]: *** [check_linux_config] Error 1
make: *** [sub-make] Error 2

<My question 2.>   Why  can not build L4 linux according to this config 

Please any help..
