Hello.

Thank you very much your great support. Where can I get your stable linux tree and configuration ?

I am using LTIB to build imx23EVK Linux BSP. How can your linux tree easly integrate into LTIB. Or should I compile using make inside linux tree ? What kind of development enviroment you are using. LTIB or anything else ? Thanks,

I have good news. I just checked all critical solders on the baord and it worked. I passed the memory check.

great news :-)

May i know login and password for linux.sb ?

superuser root without a password

Kernel panic - not syncing: No init found. Try passing init= option to kernel.

my kernel is compiled with built-in root file system in the initramfs, the filesystem on the disk is either absent or not properly assembled

Our board has some differences from the original EVK - so we use the kernel freescale of the BSP but with some patches, you can find it here
http://sasamy.narod.ru/sk_mxs.patch

To build the root file system I'm using buildroot
http://www.buildroot.org/
or openembedded
http://www.openembedded.org

I got it. Ok my friend. What about bootlets ? If you are not using LTIB, how can you get linux.sb file ? Would you explain briefly please ? Thanks.

Unpack the archive
http://sasamy.narod.ru/make_boot.tar.gz
to the root of the kernel source, edit make_kernel (required prefix = arm-unknown-linux-gnueabi- change for you toolchain ) and do
./make_kernel

.config_mmc and .config_nand - this is the configuration file for our board with the patch, it can not work on your board

simple way to integrate your own kernel in ltib - after changing the set location to your kernel source code directly

kernel (Linux 2.6.31-imx) ---> [*] Local Linux directory build
and in
(/usr/src/linux) Enter your Linux source directory (NEW)
specify the location of the source code

hi,

May I have your config files for mmc and nand to take a reference. How can I introduce your config file to LTIB as default config ? Thanks,

I reload my own binary as imx233_linux.sb. There is a kernel panic as below :

This means that you board is the same as the i.MX23 Evaluation Kit - you do not fit our patches and kernel configuration file directly. Good start for you - the documentation for the evk-board and the original kernel in ltib.

I tried to boot my device with rootfs.ext2 which is given by freescale documents. I get output below;

What is wrong with root device ? My board is already booting up on SD CARD. what may be a problem with rootfs.ext2 ? Thanks,

Hi,

Actually, my board and your board are quite similar except a few smal diffrences. Main diffrence is that I am using SSP1 for MMC and I choosed MMC booting option. So I will use ext2 file system as root file system.

I downloaded your kernel from your web site. I examined a little bit. It seems ok for me. Only I need an mmc_config for your kernel which is tailored according to mmc boot from ssp1 and ext2 filesystem which resides in mmcblkop2 in mmc. Other options could be the same. I also want to try SSD1963 LCD and KS8851 with my board. So related options could be the same with your board. No problem.

Thanks,

Hello,

As I mentioned below, if you give me a mmc_config fie inculing SSP1 MMC boot and ext2 rootfs support in for mmcblkop2 . it really could help me to get further steps. Thanks.
