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|

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 ? and What is CONFIG_ARM_PATCH_PHYS_VIRT ?
Please any help..
