Bodhi, I found the file in this thread. Debian on Synology RS816 (Armada 385)by Roland - uBoot
Hi Bodhi, QuoteThe best way is to connect serial console. Without serial console, we will just be guessing and end up spending too much time troubleshooting. I already had a serial console. All data i posted before was from that console. In my search to get more debug output i stumbled opon this form. http://e2e.ti.com/support/processors/f/791/t/541951?how-to-debug-non-booting-linux-kernby Roland - uBoot
Bodhi, Thank you for your extensive reply. I'm sorry but i forgot to mention that i want to restore the original Synology firmware just like the topic starter. Also i have a DS216 instead of a DS216j. Quote This kernel Linux-3.10.105 is too old, it does not look like it has device tree capability. I extracted "zImage" from the newest Synology .pat file, so there is no neweby Roland - uBoot
Little progress was made today. It seems that a thirth argument for the bootm command is needed to load the "Flattened Device Tree". So i did: bootm 0x02000000 0x03000000 0x01000000 Now i'm seeing this error: ERROR: Did not find a cmdline Flattened Device Tree Could not find a valid device tree I found a .dtb here: http://ftp.debian.org/debian//dists/stable/main/installerby Roland - uBoot
