Kernel problem with openwifi #279

Closed puzhitech closed 1 year ago

puzhitech commented 1 year ago

Hello, Dr. Jiao when we transplanted our SDR board, we encountered a problem that the kernel could not enter. What could be the reason? Porting is based on the latest version of 2021_r1

Is it convenient for you to transplant openwifi based on our board? In addition to the schematic diagram, what files do we need to open the source?

thank you

Hi,

I am afraid that I could help nothing here. We do the wifi part which is after linux porting is successful. Now seems like your linux porting is not done yet. We do not have much experiences on the linux part.

Some suggestions:

  1. You need to be very clear about what is the hardware difference between your board and the ADI/Xilinx reference board. (Which one is your reference? adrv9364z7020? zedboard+fmcomms2?)
  2. If there are any hardware differences, you might need to change the devicetree and some kernel configurations to align with those changes you made on top the reference board.
