I download the linux kernel from http://git.openrisc.net/cgit.cgi/jonas/linux.
But when i boot the linux, it failed..The error is :
Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

Follow is the boot information:

hi

i just read you email, and i think the problem is not in linux but in your project ise.

i see that you have fixed ngc file for ise11.1 (it's tha same problem like me in ise 10.3)

i think if you just do make arch=openrisc defconfig and then change to ml501.dts and finally make you fix the problem, because i have see this problem before i don't have many space to add thing to kernel but after this command i have fixed all.

Memory: 29960k/32768k available (2076k kernel code, 2808k reserved, 302k data, 104k init

you can see in photot that you have more than 104k

maybe try this also in ml501.dts (it's not big thing but maybe)
memory {
device_type = "memory";
reg = ;
};

you are so close to booting in ML501, don't panic :)

finally if you have try i just add my branch for ML501 master if you want to try
git clone git://openrisc.net/jonas/bakiri

Thx a lot!
i just try your way, modify the file ml501.dts to
memory {
device_type = "memory";
reg = ;
};

and type the command make clean -> make arch=openrisc defconfig -> make meunconfig -> make

but the problem is still there. When i use the or32-sim with the command or32-elf-sim -f arch/openrisc/or1ksim.cfg vmlinux, there is the same situation:

Freeing unused kernel memory: 104k freed
Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

And I cannt get resource from the link (git clone git://openrisc.net/jonas/bakiri) you gave me. that give me a error information

$ git clone git://openrisc.net/jonas/bakiri
Initialized empty Git repository in /home/dinsh/openrisc/bakiri/bakiri/.git/
fatal: The remote end hung up unexpectedly

acctually, I dont know why.. Because i remember that i can boot the linux with or32-linux-sim early but now i cannt.

sorry you must add linux in the end, use git clone git://openrisc.net/jonas/bakiri/linux

Hi nassim09!

Thx a lot! That's a good news! I see you update the linux and i git the clone of linux-3.0 repeat. Then I boot it successfully!! What a big day!

I sincerely appreciate your help!

Next step, i want to research the Linux kernel, especially the memory system. Actually, our team is committed to making a new memory just like FLASH, which is called Phase Change Memory (PCM). We want to use your ORPSOC platform as our evaluation platform. so our team is focused on OpenRisc1200 even OpenRisc2000 for a long time. And we are also willing to contribute to OpenRisc.

Thx a lot! Really!

It's good to hear that you got it working. I actually had the same problem a few days ago. We are always interested in people who wants to contribute to the OpenRISC platform. If you are using IRC, you can meet most of the active developers on #opencores on the freenode network

PSM is a very interesting topic. I hope you get good results from your research

//Olof

this is great disnsh, do you have use my git branch of linux? and it will be nice to see you in IRC

ah now i know want the problem.

when you try to do "make arch=openrisc defconfig" then some things is will be missing next.

so to fix that you must just add this thing to "menuconfig"

General setup => add "(-or32)" in local version

=> add in initramfs source files this "arch/openrisc/support/initramfs arch/openrisc/support/initramfs.devnodes

that will fix all the problems.

Hi nassim09

I try your way, add "(-or32)" in local version and add in initramfs source files this "arch/openrisc/support/initramfs arch/openrisc/support/initramfs.devnodes. yes! that can be OK. but i use the new version of linux-3.0. and i still cannt download anything from your git branch.

Thx a lot!
