Possible to develop application  on Zedboard and deploy on PicoZed ?

Former Member

I have to develop an C++ application which shall run on the PicoZed 7015 SOM.

For development, I would prefer to compile the application  on the Zedboard devlopment board.
As is noted in http://microzed.org/content/xillinux-run-ubuntu-linux-desktop-zedboard  , it seems to be possible to use the Zedboard directly as a computer (with keyboard, monitor and mouse) with a ubuntu-like desktop. So i should be able to use the usual tools (cmake, gcc, ..) to compile my C++ application and all libraries (like OpenCV).


My question is now - can I run the binaries, which I have compiled on the Zedboard, directly on the PicoZed?

    Assuming all peripherals and address map are identical, binaries are compatible on different Zynq devices, although you will require a bitstream change for the different device. (ZedBoard has a 7020, while the PZ 7015 has a 7015)

     

    That said, the peripheral sets available on ZedBoard vs. PicoZed are different. You'd have to be cautious not to use a ZedBoard peripheral that doesn't exist on PicoZed. You'd also have to manipulate the PicoZed hardware platform design to use the same address map. Otherwise, you are looking at a devicetree change.

    If you cannot develop on the production target, this is how I would do it to minimize the possibility that you get bitten by an oversight in the conversion that might hold you up indefinitely:

    1. Develop the PetaLinux project/applications for the Zedboard until you are satisfied it's complete.

    2. Build a corresponding hardware project in Vivado using PicoZed as the target.

    3. Generate a PetaLinux BSP for the new hardware platform.

    4. Copy over your applications, device tree modifications, u-boot changes (if any).  Configure the rootfs, kernel and general settings identically to the Zedboard project.

    5. Buiid, generate the boot files, and boot from uSD card.  That should work first time.

    This is not the fastest way, but it is the safest.
