PYNQ 3.0.1 can not loading Overlay: No Device Found

Hello, I’m using PYNQ 3.0.1 on my own board, the board is 7Z035 from ALinx, I have already built the iamge and boot Ubuntu successfully, but I can not load Overlay in jupyter notebook or in the terminal, get eroor: No Device Found
errorlog.txt (1.9 KB)
I have tried:
1.check /dev/xlnk, shows:

  1. source /etc/profile.d/ with sudo -i and run python ->not work
  2. export XILINX_XRT=/usr ->not work (also tried with sudo)
  3. sudo xbutil examine ,get:

Here is my spec file when build:

ARCH_Alinx7035 := arm
BSP_Alinx7035 := Alinx7035.bsp
BITSTREAM_Alinx7035 := base/7035_base.bit
FPGA_MANAGER_Alinx7035 := 1

STAGE4_PACKAGES_ALinx7035 := xrt pynq ethernet precached_metadata pynq_peripherals sdcardshrink

can anyone help me with this or give me some advice? Thanks a lot~

Hi @Xyin, it would be good if you can provide the solution, as other may find it useful as well.

Can you please provide the solution? I’m getting the exact same behavior.

Actually I just rebuilt the image using the official BSimage and rootfs. Earlier I met some errors when downloading packages, which may caused by the GFW firewell in China, but it works well after I pointed it to a local mirror server, you may not met such problem…

I also delete /boards/Pynq-Z1 Pynq-Z2 and ZCU104 folders to speed up the build process, the /boards/ dir only contains ip, sw_repo and my own board folder(I call it Alinx7035), my own board folder only contains three file:

  1. a .bit file generated by Vivado, only has the ZYNQ IP and the basic PS IO setting, located in /boards/Alinx7035/base/
  2. a .xsa file generated by Vivado, located in /boards/Alinx7035/petalinux_bsp/hardware_project/
  3. a .spec file, located in /boards/Alinx7035/, content:

ARCH_Alinx7035 := arm
BSP_Alinx7035 :=
BITSTREAM_Alinx7035 := /base/Alinx7035.bit
FPGA_MANAGER_Alinx7035 := 1
STAGE4_PACKAGE_Alinx7035: xrt pynq ethernet pynq_peripherals sdcardshrink precached_metadata

Yes, the BSP is empty, the makefile will generate a default setting file for you when you make.
And make sure you put xrt,ethernet and pynq in STAGE4

The final make command is like below:

make PREBUILT =<absolute path of BSimage>  BOARDDIR=<absolute path of BOARD folder> PYNQ_SDIST=<absolute sdist tarball path>

WARN: give PREBUILT the path of your BSIMAGE, rather than the prebuilt folder path (I know its a little strange, but it do works for me…)

I suggest you combine the offical DOC(PYNQ SD Card image — Python productivity for Zynq (Pynq)) and README file in the sdbuild folder to choose the right make command.

Hey Xyin,

thank you for your support. What do you mean by “BSimage”?

Kind regards
