boot via jtag gives "illegal option -s" error

brendansimon

Hi,

I'm new to Zynq, Vivado, and PetaLinux -- so lots to learn.

I have a PicoZed 7015 on a carrier and am trying to get PetaLinux up and running on it.  I'm using the latest version of Vivado/SDK (2015.3) and PetaLinux (2014.4 ??), installed on an Ubuntu 12.04 box.

"$ petalinux-boot --qemu --prebuilt 3" works great :)

However,

"$ petalinux-boot --jtag --prebuilt 3" fails with the following error:

xsdb: illegal option '-s'

Any idea why jtag wont work?

Is it something to do with version mismatch between petalinux and vivado/sdk?

Is there an easy solution/fix?

What's the easiest way to get petalinux up and running on on my picozed 7015 + carrier, so I can develop some linux apps.

Thanks, Brendan.

    So to clarify, I'm using the following releases.
      * Xilinux_Vivado_SDK_2015.3_0929_1
      * petalinux-v2015.2.1-final
      * Avnet-PetaLinux-BSP-PicoZed-7z015-v2014.4

    Is there a Zynq 7015 for petalinux-v2015.2.1-final ?

    Should I be using petalinux-v2014.4 instead?

    I've also installed the following to Vivado and SDK directories:
      * "Install Avnet Board Definition Files in Vivado 2015.1 v1.0_0.zip"

    Thanks, Brendan.

    Hi Brendan,

    The easiest way to create a PetaLinux project for application development for PicoZed SoMs is to use the posted BSPs on Zedboard.org.  Be careful to match the versions of Vivado, the BSP and the PetaLinux environment, or you may run into problems such as the one you are experiencing.  PetaLinux is updated on even Vivado releases, and while usually there shouldn't be a problem working with the next higher Vivado release (ie: 2015.3 Vivado with 2015.2 PetaLinux environment), this is not always ideal.  You can find instructions for using BSPs for development in Xilinx UG1144 and UG1156.

    The 2015.2 BSPs for our Zynq SoMs are delayed while an issue with USB-OTG is resolved that prevents OTG devices from being recognized.  This should be corrected in the next week or so, and as soon as the fix is available we'll be posting 2015.2 BSPs as fast as we can get them tested.

    So today, I'd recommend either using the 2014.4 BSP with a PetaLinux 2014.4 environment.   If you don't need USB-OTG and want to work with 2015.2, you can create a blank project with petalinux-create, then use petalinux-config - - get-hw-description to import the hardware platform and FSBL from your SDK project.   Detailed instructions for these commands are also found in the Xilinx User Guides for PetaLinux.
