    Zybo Z7 Pmod configuration tutorial

    in Embedded Linux

    Posted · Edited by feplooptest

    @artvvb

    I found following discussion that resolves my issue above.

    https://forum.digilent.com/topic/16877-cora-z7-board-files-m_axi_gp0_aclk-not-connected-to-clock/

    Once I generated .xsa file, I imported it into petalinux using below command. Then simply exit gui interface since I don't want additional configuration changes.

    "petalinux-config --get-hw-description ~/xilinx/zybo-7010/vivado/PmodIP/TPM_Pmod_wrapper.xsa"

    However, I eventually ran into petalinux-build error due to some DTS issues: 

    Exception: subprocess.CalledProcessError: Command '['dtc', '-@', '-p', '0x1000', '-@', '-i', '/home/leeyuc/xilinx/zybo-7010/os/project-spec/configs/../../components/plnx_workspace/device-tree/device-tree', '-i', '/home/leeyuc/xilinx/zybo-7010/os/build/tmp/work-shared/zynq-generic/kernel-source/scripts/dtc/include-prefixes', '-i', '/home/leeyuc/xilinx/zybo-7010/os/build/tmp/work/zynq_generic-xilinx-linux-gnueabi/device-tree/xilinx-v2022.1+gitAUTOINC+1b364a44fa-r0/git/device_tree/data/kernel_dtsi/2022.1/BOARD/', '-i', '/home/leeyuc/xilinx/zybo-7010/os/build/tmp/work/zynq_generic-xilinx-linux-gnueabi/device-tree/xilinx-v2022.1+gitAUTOINC+1b364a44fa-r0', '-i', '/home/leeyuc/xilinx/zybo-7010/os/build/tmp/work-shared/zynq-generic/kernel-source/arch/arm/boot/dts', '-o', 'system-top.dtb', '-I', 'dts', '-O', 'dtb', 'system-top.dts.pp']' returned non-zero exit status 1.

FATAL ERROR: Syntax error parsing input tree

    This looks like the same issue as below:

    But the issue persist even if I removed my custom change insisted-usr.dtsi file. Does this mean BSP package is not compatible with my vanilla .xsa created from local Vivado project?

    Thanks for your help.

    Hi @artvvb

    I've gathered SPI signal to MIO pin assignmenet as below:

    MISO=PMOD2—>MIO pin 11 

    MOSI=PMOD1—>MIO pin 10

    CLK=PMOD3—>MIO pin 12

    CS=PMOD0—>MIO pin 13

    I've found to configure it as below:image.thumb.png.130c3f1b052ffcba505d0f916ff8d0e9.png

    But I ran into some critical warning message:

    image.thumb.png.e674b863aa6d29542088c203981cac4b.png

    Then a clock error when I tried to validate my block diagram:

    image.thumb.png.97031ceba5c580788232a95bc948ad77.png

    I did follow clock configuration as instructed by https://digilent.com/reference/programmable-logic/guides/getting-started-with-ipi?_ga=2.123630275.937061154.1687141954-1683228566.1686966320:

    image.thumb.png.4978aea65674815b8502dfc52cc85cff.png

    Could you please tell me what I did it wrong here?

    Thanks for your help

     

    Zybo Z7 Pmod configuration tutorial

    Hi

    I want to connect Zybo SOC(Petalinux) to a TPM kit below via Pmod.

    https://www.avnet.com/opasdata/d120001/medias/docus/187/PB-AES-PMOD-TPM20-SLB9670-G-v5.pdf

    However, it is not very clear to me how to configure Pmod so that Zybo SOC SPI can communicate with my TPM kit. From following page, it seems to me that this tutorial is for earlier version. Is that any doc on how to configure Pmod? Does it still require loading a bitstream to connect TPM on Pmod to SPI bus of Zybo SOC?

    Thanks

    Petalinux build error with Zybo board

    in Embedded Linux

    Posted

    Hi

    I am trying to follow the build step in demo page.

    https://digilent.com/reference/programmable-logic/zybo-z7/demos/petalinux

    While running petalinux-build command, I am seeing a lot of errors related to python(a small portion shown below). Is there any more packages that I need to install before I can build it?

    Thanks
