Depending on the platform, it would be as simple as doing make imx_v6_v7_defconfig and then using the correct dtb for the platform. Boards like Nitrogen, Sabre or Wandaboard should boot easily with the recent kernels.

Can you provide some more information on this point? When you copied the uImage to SD card, did you do something else to perhaps update the uImage on the module, or is the module setup to boot from SD card? And what about the device tree blob?

Device tree will be absolutely required. You will probably need to set the uboot environment variables correctly. Newer kernels use the information from device tree to set things up. You probably need something like this u-boot>tftpboot 0x11000000 imx6q-sabresd.dtb u-boot>tftpboot 0x12000000 uImage u-boot>bootm 0x12000000 - 0x11000000 Have a look here. Also what is your uboot version?

Try loading the uImage to 0x10800000 and the dtb blob at 0x12000000. Perhaps that will work. So now it becomes bootm 0x10800000 - 0x12000000? If it doesn't so now this needs to be debug. Enable CONFIG_DEBUG_LL and CONFIG_EARLY_PRINTK options and see if you get some more debug messages. When I said check environment variables, I meant if there any any variables which the uboot for sabre might have predefined. It would be helpful to have a look. - Sanchayan. > > Regards > > Chirag Garg > IIT Madras , Rise Lab > > On Mon, Mar 16, 2015 at 11:09 AM, <victorascroft@gmail.com> wrote: > > > Hello, > > > > On 15-03-16 09:59:33, chirag garg wrote: > > > Hi, > > > > > > On Mon, Mar 16, 2015 at 9:45 AM, <victorascroft@gmail.com> wrote: > > > > > > > Hello, > > > > > > > > On 15-03-16 09:33:21, chirag garg wrote: > > > > > Hello , > > > > > > > > > > I perform the following steps to run linux kernel on imx6: > > > > > > > > > > Download 3.18 kernel from www.kernel.org > > > > > Make steps: > > > > > make CROSSarm-linux-gnueabi- ARCH=arm imx_v6_v7_defconfig > > > > > make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm uImage > > LOADADDR=10001000 > > > > > > > > > > cp linux-3.18.4/arch/arm/boot/uImage Sd_card > > > > > > > > So you copied the kernel image to SD card. > > > > > > > > > Run uImage on the imx6 board... > > > > > > > > Can you provide some more information on this point?
