SK-AM62: NFS boot: Bad Linux ARM64 Image magic!

Thorsten Lorenzen

Part Number: SK-AM62

Still I cannot boot via NFS while SD Card boot is fully functional. I have read all he the tickets for Jacinto but for Sitara it is not working.

Applying the ./setup.sh script works but always ends up with "Bad Linux ARM64 Image magic!" even it seems to load the "Image-arm62xx-evm.bin" and the "k3-am625-sk.dtb" files. I have two IP addresses and difficulties to decide what is the right one.

Any ideas what I can do?

Hi,

I may be missing something but I don't see where any files are loading. All I see are timeouts. You need to verify there is communication with the server. Try pinging the server address after this boot sequence exits. You will need to an ip address already such as the 192.168.178.126.

Which SDK are you using? What is providing the role of the tftp server?

Best Regards,

Schuyler

Hi Schuyler, sorry took me time to understand what needs to be changed.

First of all I had to switch the VirtualBox into "Bridged Mode" in order the Ubuntu host receives a dedicated IP address from my router.

Now not just the windows machine (192.168.178.129) but even Ubuntu VM guest (192.168.178.130 ) have own unique IP address for tftp to function. The EVM even received the IP address (192.168.178.111). I can ping all IPs (WIN PC, Ubuntu VM, EVM).

What I found is in the log of the terminal the "FTP from server 192.168.178.1" is my router. Shouldn't it be "FTP from server 192.168.178.130" to address the Ubuntu host VM in order to connect via tftp/ftp?

Any idea?
