RE: Impressions on the RIoTboard and changing its Operating System in Windows

Tutorial is very good. Ran into a problem when the rootfs is being installed. Looks like the system has run out of memory:

UTP: received command 'pipe tar --numeric-owner -zx -C /mnt/mmcblk0p1'

pid is 2950, UTP: executing "tar --numeric-owner -zx -C /mnt/mmcblk0p1"

UTP: sending Success to kernel for command pipe tar --numeric-owner -zx -C /mnt/mmc blk0p1.

tar invoked oom-killer: gfp_mask=0x200d2, order=0, oom_adj=0, oom_score_adj=0

Could there be something wrong with the board or did I miss some configuration parameter ? Used the element-14 linux.zip. Any way to get a smaller ubuntu rootfs ?

Thanks for this nice tutorial. Just followed the steps - unfortunately the image can't be written.

On the serial terminal I find the following messages:

This happens just after uploading and starting the Linux kernel with the help of the MfgTool. The error messages claim that the onboard eMMC can't be mounted and therefore the MfgTool can't continue to flash the Ubuntu image.

What can be done in this situation?

Hello Christopher,

Great article. I'm relatively new to Linux but with your help I was able to install it on my RioTBoard. One problem -- What is the root password for linaro?

Thanks
