EBV SoCrates Board - Linux 3.10 Kernel stops in the middle of nowhere

Hi, 

 

I'm pretty new to Cyclone V SoCs and also to Linux in general. But I already managed to compile a Linux Kernel 3.10 with the cross compiler toolchain (eldk) provided by www.denx.de (http://www.denx.de). I also got a root fs from denx.de. 

 

Okay, on the Socartes board provided by EBV, there is a micro SD card which already has a running system ready to boot a linux system. This works fine. 

 

I started by setting up u-boot (by stopping the normal linux boot and changing some environment variable to my needs like IP adresses and device tree blob file name, etc). I am able to load my compiled kernel 3.10.17 from my development host for booting on the SoCrates Board (via NFS). I also provide a dtb file which I compiled from the dts file that is provided in the kernel git repository. I also load this file via NFSD to the board at bootup. 

 

The kernel seems to start correctly but then stops after it writes out "stmmac_dvr_probe: warning: cannot get CSR clock". After some time I get some dumps (?!?) or whatever that may give a hint about what the kernel is doing while not booting anymore. I attached everything (from the boot command in the u-boot console until the aformentzioned dump) into the attachment. 

 

The last line that the kernel displays to me seems to have something to do with the Ethernet connection. Maybe I have not compiled the correct ethernet PHY driver into my kernel. But that is just a guess because as I said I'm very unexperienced with Linux kernel internals. 

 

I'm happy about every hint or advise from somebody that is more experienced than I am. 

 

Regards, 

Maik

Hi,  

 

somebody recently got the same problem like I have : http://lists.rocketboards.org/pipermail/rfi/2013-october/000633.html (http://somebody recently got the same problem like i have : http://lists.rocketboards.org/pipermail/rfi/2013-october/000633.html

 

It is said, that I should not use mainline kernel but the git repository from rocketboards.org. 

 

Okay, I tried that, but it seems as if the server does not answer properly on my git clone request (neither via git port nor via http). 

 

What is wrong, there?
