i.MX Yocto Project: ltib versus bitbake

[dominicamann]

I have a few questions that I haven't seen addressed.

1. Is there a specific yocto configuration for the kontron board?
2. Can yocto boot off of usb?
3. Can yocto be nfs booted?

[LeonardoSandova]

1. For non-FSL boards, you need to check this layer/folder meta-fsl-arm-extra/conf/machine at master · Freescale/meta-fsl-arm-extra · GitHub

2. You mean booting from the USB OTG? i.MX USB Loader

3. Sure. Just do the proper changes on u-boot. Use the images from tmp/deploy/images

[EricNelson]

Hi Leonardo,

The link you posted above (DOC-9411) returns "may have been deleted"...

[dominicamann]

I could not find anything for kontron in the 1st link – I am following up with them.

The second link is a 404.

I will try the images created – although I am not sure what to do with the u-boot image file.

Thank you,

Sorry, wrong copy & paste. Now the link is non-404.

[EricNelson]

Hi Dominic,

Ironically, I was just sending a note to another customer when I saw your question.

I don't know whether Kontron's U-Boot build includes USB support, but in general, U-Boot supports USB storage

devices.

We have some patches in flight to allow booting via USB on our boards, but the USB startup is slow under

U-Boot, so we haven't integrated them into our boot script.

If you want to do this by hand, you can use something like this:

    U-Boot > usb start

    U-Boot > setenv bootargs ... rootwait root=/dev/sda1

    U-Boot > ext2load usb 0 10800000 /boot/uImage

    U-Boot > bootm 10800000

That is, the "usb start" command should initialize the USB driver (and recognize the storage device), and the "fatload" or "ext2load" commands will allow you to read a kernel into RAM.

You'll then need to tell the kernel (via "bootargs") where the root filesystem is located (example above assumes partition 1 of the first drive connected to your system).

[LeonardoSandova]

What do you mean by 'I am not sure what to do with the u-boot image'?

[dominicamann]

The image in deploy/images called u-boot.imx is the one I wouldn't know what to do with - perhaps it is for OTG?

In general, the kontron supports usb boot. I did not mean usb OTG I meant usb boot as in boot from a usb memory device (as opposed to SD card).

I have a u-boot configuration that boots from USB for the LTIB distribution successfully . I have tried building yocto (for imx6sabresd) and dd-ing the image to my usb stick - but no success. I also tried a single ext2 partition, copy filesystem, add uImage in /, then run grub-install. That didn't work either. I will try again with Eric Nelson's directions below.

[dominicamann]

Tried this - hangs at "Starting kernel" (after checksumming and loading ok).

[EricNelson]

Hi Dominic,

Believe it or not, that means things worked...

Now you just need to figure out what the proper value for "bootargs" needs to be. You can probably cut & paste from a successful SD card boot and replace "/dev/mmcblk0p#" with "/dev/sda#" and be up and running.

[dominicamann]

Sure. Oddly enough, it works on an LTIB image - the only obvious difference is the LTIB has its uImage in / - so I had to change my bootfile variable to make it work. Yocto still doesn't work.

I will try with the uImages in the same place. Although by now this feels more like superstition than science. Is there some way to have the boot give more diagnostic progress information?

The usbboot boots the LTIB usb stick no problem. uImage is in the same place (/boot/uImage) in each case. Root filesystem is in /dev/sda1. The command is the same.

[LeonardoSandova]

Are you using dora? Kernel 3.0.35 ? BTW, u-boot.imx is the same as old u-boot.bin, just without the padding.

[dominicamann]

The kernel shows as 3.0.35-1.1.0+yocto+g21304e.

The Yocta build was dylan. Should I use Dora?

I am accustomed to bios boots on linux systems. Is there something I need to do with the uBoot imx file? Does it get copied to the boot device somehow? I thought my kontron board has u-boot on its flash so I can run these commands as above. Is there a u-boot component that goes on the boot device as well?

[OtavioSalvador]

Yes; Dora is the current stable version and all new products ought to be based on it as it gives you a good base and easier upgrade for future releases.

Kindly help, it is my first build.
