0. Could you send email to xianjun.jiao@ugent.be to introduce your self? Sent

1. Our image is used directly or you build your own image? I used the image "openwifi-1.4.0-notter.img" unzipped from "openwifi-1.4.0-notter.img.xz".

2. What is your own modification? No modification

3. Versions: OS, Vivado, openwifi/openwifi-hw repo branch and commit revision Ubuntu 22.04.3, openwifi-1.4.0-notter.img , Vivado not used yet

4. Board/hardware type Zed board , AD-FMCOMMS3-EBZ

5. WiFi channel number Not reach this step so far.

6. Steps to reproduce the issue, and the related error message, screenshot, etc

I followed the quick start instruction : a. flash SD card with image openwifi-1.4.0-notter.img; b. copied all files in the folder Boot/openwifi/zed_fmcs2/ to Boot/; c. check these two folders rootfs/root/kernel_modules rootfs/etc/network/interfaces.new and confirm these two don't exist; d. configure the Zedboard boot to enable boot from SD card; e. insert SD card to Zedboard sd card slot with lock switched off; f. connect Zedboard to network switch and connect my laptop to network switch too; g. switch the Zedboard board on and I could login to the board from my PC (SSH) .

I used 32 GB SD card then : raspi-config --expand-rootfs After finishing : reboot I connected to the board again then : ./openwifi/setup_once.sh

After finishing, I manually rebooted the board. Then, I reconnected to the board, and you can see the errors in the following steps:

usage:
  Script for load (or download+load) different driver and FPGA img without rebooting
  no  argument: Load .ko driver files and FPGA img (if system_top.bit.bin exist) in current dir with test_mode=0.
  1st argument: If it is a NUMBER, it will be assigned to test_mode. Then load everything from current dir.
  1st argument: If it is a string called "remote", it will download driver/FPGA and load everything.
  - 2nd argument (if exist) is the target directory name for downloading and reloading
  - 3rd argument (if exist) is the value for test_mode
  1st argument: neither NUMBER nor "remote" nor a .tar.gz file, it is regarded as a directory and load everything from it.
  - 2nd argument (if exist) is the value for test_mode
  1st argument: a .tar.gz file, it will be unpacked then load from that unpacked directory
  - 2nd argument (if exist) is the value for test_mode

8. Describe your debug efforts by Linux native tools, such as tcpdump and "cat /proc/interrupts"

9. Describe your debug efforts by: https://github.com/open-sdr/openwifi/blob/master/doc/README.md#Debug-methods

10. Any other thing we need to know for helping you better? I tested it with a 16GB SD card and used Windows to write the image file on it, but the errors remained the same.

It is working now.
