Closed rookiebeotch closed 1 year ago

rookiebeotch commented 1 year ago

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

  2. Our image is used directly or you build your own image? your image directly.

  3. What is your own modification? no modification. only doing ap to client tests in iperf

  4. Versions: OS, Vivado, openwifi/openwifi-hw repo branch and commit revision openwifi-1.3.1-wilsele-1-32bit.img

  5. Board/hardware type zedboard with AD-FMCOMMS4-EBZ

  6. WiFi channel number 44 in 5G

  7. Steps to reproduce the issue, and the related error message, screenshot, etc Here is the kernel dump from serial uart.

  8. Describe your debug efforts by Linux native tools, such as tcpdump and "cat /proc/interrupts" none

  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? was trying to see the performance on zedboard. was running as an AP using scripts wgd.sh 1. ran iperf in client mode to a laptop connected as a wifi client to zedboard(which is AP).
