We are trying to fix everything. More people help us, faster we can have a working gcc suite..

Thanks mate! Replied!

I'm trying to run an e500v2 machine. Not Mc, not M1. A v2 because I need to test math library under linux
I've also found a powerpc spe freebsd version but same result

Well, don't you think i've tried lot of distros without results?
I've donwloaded ubuntu-14.04-server-powerpc.iso, extracted vmlinux and initrd.gz, downloaded a file called wirtio-win.iso from a fedora web site.. and then nothing happens when I run the command. qemu seems stuck.
Not only. Not all distro has the same kernel file. For example freebsd has a file called KERNEL but not initrd.gz.
That's why I'm asking for something ready that is working for someone. Is it so hard to share two files?

I need your files because I don't have any of them. No kernel, no initrd and so on. I have only the iso files and of course you don't have to give me them. Just the minimum to make the machine work correctly like yours

Well,
Can you please send me everything?
I mean vmlinux and so on?

Thanks

Of course it is a dirty toolchain file i'm using. And sometime I play with it but it should work for any project

Did you see -L/opt/code/ogles2/local/newlib/lib?
You are pointing to newlib lib folder and not clib2 one and you have the error:

/opt/code/ogles2/local/newlib/lib/libogles2.a(Clear.o): In function `glClear':

That show you are using newlib version

Great. Of course if you fix problems or add something feel free to push your changes

You are using newlib. I've compiled it using my clib2 version. However with some small changes it must work also with newlib since most of the code is OS4 code.

I've cross compiled it using gcc11 and cmake as usual.
I've created in my machine a tool chain file that I use every time I want to use cmake so I have less ptoblems

Because it isn't working. Why don't you try to run it? I've tried several ppc iso and uboot doesn't boot anyone of them. Using virtio I can see the HD and the cd using virtio scan and info. If I add an ahci controller I can see it in pci list but none of them it is booting. If you find an iso that is working please tell me please where I can download it and give me the exact command line that works with e500

Ok. That's fine. But except for the Linux iso. I don't have the kernel, initrd and so on. Do I have to compile it? Or it is possible to download them somewhere?

The only devices that seems usable are virtio-blk. And reading the second link you gave me there is also an example. But there is no way to make it work..

Yes I saw this. But this isn't the problem. The problem is that with shipped uboot e500 version I can't manage to add any drive. In any way.

Yes. It is that one I want to run. But no ide or scsi devices are recognized. I've tried several ways. Tomorrow I will try on Linux x86

It seems you are running it on Linux (PPC) and not on Windows (or lunux x86) for example. However where I can find all I need? I mean uboot and the kernel?
Thank you

I've tried with:



But it doesn't work. U-boot starts but no ide/scsi devices are found and so the autoboot fail

Thanks joerg

since there are a lot of people that is using QEMU. Can anyone has tried version 8.1 with e500v2 and PPC Linux? Is there a way to use ide bus? Because it seems it doesn't have any ide or scsi bus available.
Any hint?

I need to get (and set) the floating-point exception mode.
I’ve seen that in exec/interrupts.h there are:



That should be get and set via ReadTaskContext/WriteTaskContext. Now my question is. Is the only way to get that register? Is it the correct way? Is there a #define to get only the bit I need?

Thanks
