Re: Building Linux kernel

How is the initrd file built? Is it an image of a fs or a cpio file? I think that nowadays it's cpio format that is used (cpio archive compressed with gzip). I don't know if the format can be chooses when building the kernel. And then, you pass it to the kernel using initrd= ? I'm willing to help fo...

Re: Building Linux kernel

Ok. If I understand correctly the Linux rootfs which is now on its own partition will be replaced by an image that would be on that exFAT partition. Why not ? This way you can update the Linux part by just replacing the image on the exFAT partition. A simple way to avoid corruption would be to mount...

Re: Building Linux kernel

I agree with alfishe, having the linux rootfs on a ext4 partition makes it hidden in windows and a separate partition on linux. This way the chances of removing files from the rootfs partition is limited. It's a good thing to leave it in a dedicated partition. Plus how does a linux behave with a roo...

Re: DE-10 nano temperature issues

You're right about saying that using thumb2 generates more heat. I'll do the same testing with the same u-boot passing maxcpus=1 to the kernel and two kernels built with the same compilator and the only difference being the THUMB2 option and see if the results are the same. I also agree on the fact ...

Re: DE-10 nano temperature issues

I eventually manager to compile a working kernel, my point was to see how the heat issue would be with two core running. Since there is only one main running process (MiSTer), when there are two running cores, the second core is almost all the time at 0%. So there is no real difference between one o...

Here's what I've done : I cloned the folowing github : https://github.com/MiSTer-devel/Linux-Kernel_4.5.0_MiSTer I also tried by downloading the zip file which by the way is named Linux-Kernel_4.5.0_MiSTer-socfpga-4.5....

However, they say that everything is opensource but I can't find the source of the coprocessor. And about the softCPU, I suppose that there is no opensource implementation of the...

Re: No Atari ST core?

The creator of the MiSTer has said in multiple occassions that he has no interest in the ST because he considers it a bad system so there is very little likelihood that the ST core will be ported over. Now, why Sorgelig decided to use an Atari ST forum for MiSTer is a bit of a mystery. I wouldn't u...

Re: VGA --> RGB for 1084S Monitor (solved!)

It's the same cable as for MiST, you can buy it from here :
http://lotharek.pl/product.php?pid=168

EDIT : This cable has a SCART connector at the other end and is for TVs.
But you can use the schematic to build your own cable for the 1084s.

I believe Mi in MiST comes from Amiga, that is... Mig, as in MiniMig. :)

That's the second explanation, after the minimig core got ported to MiST. But MiST was first built to implement an ST Core.

It a "better" MiST. That's for the name. As the MiST was named si because of "Mini ST".
MiSTer is related to MiST not to ST.
ST can be ported to MiSTer, all it needs is some developer willing to port it to MiSTer.

Re: Arcade cores

That's some ambitious project that might give good results. Provided that developers have ideas and motivation to program games for it.
I thing the hardest part is to find new ideas of games. But writing clones of existing games might be fun too.
