I see same problem in qemu with 3.19-rc1 kernel when doing DT boot. In qemu I'm using direct booting from OneNAND (X-Loader --> NOLO --> kernel) without U-Boot. After NOLO load & boot kernel I do not see any other output from serial console. Also on qemu screen there is no new output (just NOKIA logo from bootloader). I do not have this problem when doing legacy/board code boot with 3.19-rc1 kernel, so this problem is related to DT. Kernel 3.18-rc1 worked fine for both DT and legacy boot. Can somebody look what broke DT booting? -- Pali Roh?r pali.rohar at gmail.com -------------- next part -------------- A non-text attachment was scrubbed...
