Linux zImage riotboard

[erikfriesen]

As near as I know, I have followed these steps

RIoTboard: Linux on the RIoTBoard Part 2: Kernel | element14

The first time on a digital ocean server everything worked as expected.  I have zipped the linux build and transferred it to a local machine, and now the device won't boot anyway I can figure out.

After putting the new zImage in /boot/ I get this

Hit any key to stop autoboot:  0

Changing the boot.scr to boot a uImage, I get this

So is there some factor I am missing here?

If its is a factor, emdebian doesn't host the toolchain anymore, could the gcc be a factor here?  I did an apt-get install gcc-arm-linux-gnueabihf

Hi Erick,

It is not clear the procedure you follow up to Zip the zImage, Generally zImage is not too big to be zipped, I suggest not compress this file and copy/paste directly to the device. If in any case you suspect of the gcc toolchain, please download a try with linaro toolchain such as:

https://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.9-2...

hope this helps

I zipped it using bzImage.

In the end it was a combination of compiler and some obscure option I must have had wrong.  Updated to linaro 4.9, called make imx_v6_v7_defconfig to reset the options, and it worked.
