I can't get anywhere trying to boot a devel device tree kernel on Cubietruck.
This is with https://github.com/jwrdegoede/linux-sunxi.git and the linux-devel branch. I don't get any boot output. I can boot a 3.4 kernel without problem. I followed these steps. http://linux-sunxi.org/Mainline_Kernel_Howto I also tried turning on low level printk but still no output U-Boot SPL 2014.04-10675-g44b53fd (May 19 2014 - 20:39:18) Board: Cubietruck DRAM: 2048 MiB CPU: 960000000Hz, AXI/AHB/APB: 3/2/2 spl: not an uImage at 1600 U-Boot 2014.04-10675-g44b53fd (May 19 2014 - 20:39:18) Allwinner Technology CPU: Allwinner A20 (SUN7I) Board: Cubietruck I2C: ready DRAM: 2 GiB MMC: SUNXI SD/MMC: 0 In: serial Out: serial Err: serial Net: dwmac.1c50000 Hit any key to stop autoboot: 0 sun7i# tftp 0x49000000 /var/lib/tftpboot/ct.dtb dwmac.1c50000 Waiting for PHY auto negotiation to complete........ done Speed: 1000, full duplex Using dwmac.1c50000 device TFTP from server 192.168.1.50; our IP address is 192.168.1.51 Filename '/var/lib/tftpboot/ct.dtb'.
