the source code of RiotBoard

plz download user manual here

user manual comes with build instructions and other details for getting started.

use links below at linux terminal to pull toolchain,uboot and kernel from our repository.

  git clone git://github.com/embest-tech/fsl-linaro-toolchain.git

  git clone git://github.com/embest-tech/u-boot-imx.git -b embest_imx_3.0.35_4.0.0

  git clone git://github.com/embest-tech/linux-imx.git -b embest_imx_3.0.35_4.0.0

let us know if u have challenges in build.

when I use the source u give to compile uboot

i entered :  make distclean

it says:

could not find distclean.

"could not find distclean" means the code doesn´t have a make option for distclean.

You can try "make clean" instead.

But if you just checked the code out from github you normally don´t need to execute distclean.

I have some blog posts on how to compile u-boot with debian wheezy.

Also on how to compile the kernel. THe kernel is mainline in those descriptions. But it should also work with the code from embest.
Mainline has no GPU/VPU drivers integrated.

You find that blogs here.

Linux on the RIoTBoard Part 1: U-Boot

I use the serial port to print some logs and find problems bellow:

when it excute linux-imx/arch/arm/kernel/process.c

it has a funtion:

void cpu_idle(void)

when the program entered this function, there is a while(1)

after some loops when it entered the function: "schedule();"  again.

Then it never return back and it will print the logs I give bellow:

would u please give me more suggestions?

have u achieved to compile this link of source code?(

git clone git://github.com/embest-tech/fsl-linaro-toolchain.git

  git clone git://github.com/embest-tech/u-boot-imx.git -b embest_imx_3.0.35_4.0.0

  git clone git://github.com/embest-tech/linux-imx.git -b embest_imx_3.0.35_4.0.0

)

if not , would u please give me an correct edition?

I've closed wireless and SMP part via "menuconfig",but the problem still alive:
