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? 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? Did you have a look at the uboot environment variables? What was the earlier kernel version the board was booting with?

Output :

## Booting kernel from Legacy Image at 10800000 ... Image Name: Linux-3.18.4 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 5445640 Bytes = 5.2 MB Load Address: 10001000 Entry Point: 10001000 Verifying Checksum ... OK Loading Kernel Image ... OK OK

Starting kernel ...

what could be the problem in this ? why Is this kernel not able start on imx6 platform ?

That output is on the serial debug console? Is the console parameter in uboot set appropriately to what the kernel expects? - Sanchayan.

Thanks in advance, Regards,

Hi all,

I am new to the linux kernel source code. I want to compile linux source code for imx6 ARM based platform. I want to generate raw binary image (.bin file) and .dtb file. Can any one help me in this.?

Which iMX6 platform is this? 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.

I am using freescale imx6 quad core saberlite board. Available on the freescale site http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q

Where should be this dtb available according to the board. I am trying to boot 3.14 linux kernel.

The DTS files for all ARM boards are available in the following directory

http://lxr.free-electrons.com/source/arch/arm/boot/dts/?v=3.14

http://lxr.free-electrons.com/source/arch/arm/configs/imx_v6_v7_defconfig?v=...

imx_v6_v7_defconfig is the config file for imx platform.

-Regards, Sanchayan.

Do you have a custom board or one of those easily available development platforms?

Board is easily available in the market.
