I tried the patch again and find it's working on my Linkstation LS-WTGL (orion5x with 64M memory) I already send the news to another post [0] So the patch enclosed at the end already confirmed to be working for 3 different kernels: - jessie-backports: linux-image-4.3.0-0.bpo.1-orion5x (4.3.3-2~bpo8+1) - sid: linux-image-4.3.0-1-orion5x (4.3.3-5) - experimental: linux-image-4.4.0-rc8-orion5x (4.4~rc8-1~exp1) >>> cp.b 0xff200000 0x800000 0x3fffff >>> setenv bootargs console=ttyS0,115200n8 root=/dev/ram rw >>> initrd=0x800000,0x3fffff >>> bootm 0xff000000 > >> u-boot loads it like this: >> >> ## Booting image at 00400000 ... >> Load Address: 00008000 >> Entry Point: 00008000 > > I also don't understand where the address "00400000" comes from.
