Hi Supriya,

Here are some answers:

1. Recommended toolchain for 32-bit ubuntu OS

$ sudo apt-get install gcc-arm-linux-gnueabihf

2. Uboot source code

GitHub - boundarydevices/u-boot-imx6 at boundary-v2015.07: U-Boot branch to support the Freescale i....

Use the nitrogen6q_defconfig since both Nitrogen6x and SabreLite share the same config (as very close).

3. Kernel source code

GitHub - boundarydevices/linux-imx6 at boundary-imx_3.14.28_1.0.0_ga: Boundary Devices Kernel tree f...

Use boundary_defconfig, this will build the imx6q-sabrelite.dtb device tree.

4. Compilation procedure

https://boundarydevices.com/cross-compiling-kernels-2014-edition-2/

5. SD card preparation procedure

Hope this helps.

Thank you Gary.

I have prepared images for uboot and kernel. Now exploring on rootfs.

Should I prepare root file system or is thr rootfs readily available for me to use?

Hi Supriya,

If you flash our Trusty image to an SD card, everything will be ready to do for a SabreLite board. You shouldn't even have to compile the kernel or u-boot unless you want to customize them.

BTW I didn't notice your board name but SabreLiteSD doesn't exist, it is either SabreSD or SabreLite.

Regards,

Gary

Hello Gary,

Thanks again for your reply. It is SabreSD board.

For environmental sert-up it is not needed, so I can use pre-built images.

But am trying for the secure booting, where in secure configuration related macro needs to be modified to enable secure booting, hence am trying to build and flash it in sd card.

When I used u-boot.imx and prepared sd card, it was booting up with freescale logo on LCD screen

When I used u-boot.bin and prepared sd card, I was not able to see anything on LCD screen and serial console as well.

     dd if=u-boot.bin of=/dev/sdc bs=512 seek=2 conv=fsync

Above is the command I use to prepare the sd card. Please confirm, which binary should I use?

Hi Supriya,

If it's SabreSD, please modify the title of the post (if possible). Also forget all my answers, they only apply to SabreLite, not SabreSD.

Gary

Hi Supriya,

Under the Solou can see the follow information, here you can see many version of BSP and you can choose one version you need:

• Run-time Software (37)
  • Operating System Software - Board Support Packages (32)

And under the Hardware Development Tools you can see the download tool mfgtool in the Programmers link:

• Hardware Development Tools (13)
  • Programmers (Flash, etc.) (9)

And in the documents link you can see the documents to match all the version BSP, you can refer to the use guide document. There are details on how to build the platform and build the BSP and how to run them on your board.

Hope this can help you. If any questions contact me easily.

Have a nice day
