Kernel panic - not syncing: No init found. Try passing init= option to kernel.
So, I have some questions:
1) I have just 8Mbyte SDRAM and it is mapped in default 16 Mbyte pretty bad: 2Mbyte active memory followed by 2Mbyte of unavailable, then again 2Mbytes active followed by.... In kernel configuration I chose 16Mbyte sdram. But, I tried to make a very small uclinux memory footprint in order fit into 2Mbyte active memory. The question is, how uclinux work with memory that is "outside" image. (e.g. organizes stack, heap etc). If it is really needed i may fix board to have 8Mbyte active memory followed by 8Mbyte unused(and probably will do this in future).
2) In menuconfig in kernel/library/defaults section is written
Libc is None
is it normal?
3) As i said i reduced footprint and probably missed something important. Can you check attached files?
config.linux-2.6.x
config.vendor-2.6.x

Mike Frysinger (UNITED STATES)
Message: 53073 you're booting a kernel without a root filesystem attached. that means you either need to provide an external filesystem (in say flash), or you need to boot a different kernel image.
it'd be a lot saner to just use 16megs of SDRAM instead of trying to force fit 8megs. if you still want to try to boot 8megs, you'll most likely need to use the memmap= kernel arg as well as only be able to boot out of flash. a kernel image with an attached filesystem will not realistically fit into a two meg chunk. you also will have fragmentation problems probably much worse than normal.
the libc in uclinux-dist should be set to none. that means no library will be built up when you build uclinux-dist -- this is what you want as you already have a C library with the toolchain.

Message: 53177 Thanks Robin and Mike.
I've created rootfs.jffs2, vmImage and loaded them to flash. Then i started kernel with setenv bootargs root=/dev/mtdblock2 rw rootfstype=jffs2 mem=6M memmap=2M$2M (to use 4Mbytes of memory 2 at the beginning and 2 at the end). And received the following:
bfin> setenv bootargs root=/dev/mtdblock2 rw rootfstype=jffs2 mem=6M memmap=2M$2M
bfin> bootm 0x20040000

Message: 53182 the generic board file does not declare any flash resources, so the physmap flash driver would crash if you attempted to load it. you should be creating your own board resources file and making sure to declare proper physmap resources. please consult the other board definition files which do this properly.
this document also touches on the flash resources at a higher level:

With u-boot checked that file /bin/init exists, so i tried
setenv bootargs root=/dev/mtdblock2 rw rootfstype=jffs2 memmap=2M$2M mem=6M init=/bin/init
and the output was almost the same except the last line

Failed to execute /bin/init. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
What solution can be in this situation?
probably i can use any of *.initramfs files from uclinux-dist/images (uImage.initramfs, linux.initramfs)?
There is also an error "sysfs: duplicate filename 'physmap-flash.0' can not be created". (maybe duplicate because i set in kernel options for flash offset and length (and also defined partition in /boards/myproj.c) )

Message: 53328 getting -EEXIST errors from the physmap driver means you declared both board resources as well as setting the sizes in the kernel configuration menu. you should only be using one method. the kernel configuration options are deprecated, so you should stop using that.
for your root filesystem, verify you programmed the image at the same offset that you're declaring. in other words:
0x00100000-0x00400000 : "RootFS"

in board configuration file i commented CONFIG_MTD_PHYSMAP and CONFIG_MTD_PHYSMAP_MODULE so that flash would be loaded not depending on them.
//#if defined(CONFIG_MTD_PHYSMAP) || defined(CONFIG_MTD_PHYSMAP_MODULE)
&sorex_flash_device,
//#endif
(and the same for partition definition)
But now I do not even see any partition like in log before....
And here

Message: 53475 I finally get the correct physmap work with enabled MTD_PHYSMAP.
Now, when I boot I do not see any error message. Process just stops (see log1). When I changed /dev/mtdblock2 to /dev/mtdblock1 I've slightly different output(see log 2), according to which I assume that kernel finds rootFS right but can not make any steps forward.

if the kernel is getting hung up, this is where you'll need to start debugging due to your non-standard memory setup ...
