Booting mainline kernel with mainline u-boot from SD on RIoTboard

[michaeloberle]

I am trying to boot an SD card image with a mainline u-boot (10.2014), mainline kernel (3.19) and debian rootfs all of which I have cross-compiled in a debian VM.

Since I am not a linux guru I am trying to give you as much information as I can for the process of creating the image, u-boot and the kernel.

This is the output I am receiving from u-boot now:

I guess that u-boot does not look for the kernel on the SD card but since I am new to u-boot I don't know what I need to change.

This is how I build the component which is a mixutre of (http://www.element14.com/community/community/designcenter/single-board-computers/riotboard/blog/2014...) and risc-a-day: Mainline Linux for RIoTBoard

U-boot

export ARCH=arm  
export CROSS_COMPILE=arm-linux-gnueabihf-  
export OUTPUT=/home/riotboard/linux/output  
wget ftp://ftp.denx.de/pub/u-boot/u-boot-2014.10.tar.bz2
tar xf u-boot-2014.10.tar.bz2 && cd u-boot-2014.10
make distclean && make riotboard_defconfig && make u-boot.imx -j4

Kernel:

export ARCH=arm  
export OUTPUT=/home/riotboard/linux/output  
mkdir ~/riotboard
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.17.tar.xz
tar xf linux-3.17.tar.xz && cd linux-3.17
make distclean && make imx_v6_v7_defconfig && make LOADADDR=0x10008000 uImage -j4
cp arch/arm/boot/uImage ~/riotboard/
cp arch/arm/boot/dts/imx6dl-riotboard.dtb ~/riotboard/
make modules_install INSTALL_MOD_PATH=~/riotboard

Side question: what does the LOADADDR argument to in the make command?

I will skip the rootfs here becuase these IMHO is not the problem here yet.

I have created the SD card image in the following way  (http://www.element14.com/community/community/designcenter/single-board-computers/riotboard/blog/2014...)

apt-get install qemu-utils kpartx 
cd /home/riotboard/linux/output
qemu-img create sdcard.img 3600M  
sfdisk --force -uM sdcard.img << EOF  
10,,83  
EOF
kpartx -av sdcard.img
mkfs.ext2 -j /dev/mapper/loop0p1  
mkdir -p /mnt/sdcard  
mount -t ext2 /dev/mapper/loop0p1 /mnt/sdcard 
tar --numeric-owner -C /mnt/sdcard -zxvf oneiric.tgz  
tar --numeric-owner -C /mnt/sdcard -zxvf linux-kernel-3.19.tgz
umount /mnt/sdcard  
kpartx -dv sdcard.img
dd if=u-boot.imx of=sdcard.img bs=512 seek=2 conv=notrunc  

I hope someone can point me in the right direction!

Thank you!

When the board is up, it will run the bootcmd first. So, in the bootcmd, there will loading the zImage to memory first. e.g. you can load the zImage from MMC or load from the network through tftp. Then create the final 'bootargs'. Then the 'bootargs' pass to the kernel. It will be the kernel command line.

In your case, the bootargs  = console=ttymxc1,115200 root=/dev/nfs ip=dhcp nfsroot=:,v3,tcp

The board is booting from NFS. But the path of nfsroot is missing.

You can find more example and information from the i.MX Linux User Guide.

[michaeloberle]

Thank you for the answer. The guide is nice for giving more infos to the basics of i.MX6. But as far as I know the addresses for the riotbaord are different.

Nonetheless I have made some progress:

setenv bootargs $bootargs rootwait root=/dev/mmcblk0p1
mmc dev 0
ext2load mmc 0 10800000 /boot/uImage
bootm 10800000

It appears that the u-boot is loading the kernel now but the kernel cannot find the rootfs or the dtb file??

## Booting kernel from Legacy Image at 10800000 ...

Does anyone hvae suggestion?

[fabio_estevam · Accepted solution]

You are loading and booting only the kernel.

You also need to load the dtb into run and then boot like: bootm <kerneladdress> - <dtbaddress>

Regards,

Fabio Estevam

[michaeloberle]

Thank you Fabio! That was a very valuable hint!

I have loaded the dtb and now the kernle is booting!

setenv bootargs $bootargs rootwait root=/dev/mmcblk0p1
mmc dev 0
ext2load mmc 0 10800000 /boot/uImage
ext2load mmc 0 16800000 /boot/imx6dl-riotboard.dtb
bootm 10800000 - 16800000

Now it appears that the kernel cannot find the rootfs and tries to look for it on the network where of course there is not kernel - it is on the sd card.

Do I also need to load the rootfs?

=> bootm 10800000 - 16800000

Michael,

Your command line looks confusing:

console=ttymxc1,115200 root=/dev/nfs ip=dhcp nfsroot=:,v3,tcp rootwait root=/dev/mmcblk0p1 rootwait root=/dev/mmcblk0p1 rootwait root=/dev/mmcblk0p1

It mixes NFS boot with mmc rootfs.

You could either try a NFS boot or to store the rootfs in the sd/mmc.

Regards,

Fabio Estevam

Yes, Fabio! You are right! I figured it out as well before the post was moderated.

I had altered the bootargs incorrectly.

setenv bootargs console=ttymxc1,115200 rootwait root=/dev/mmcblk0p1

This solved the issue!
