Start with Openwifi

[Maxelectronics]

I am currently trying to implement Openwifi on an ADRV9361-Z7035-BOB board and I would like to know where exactly we should copy the BOOT.bin and devicetree.tdb files? One more thing, when we want to connect the board to our PC, should the Ethernet cable from our PC be connected to the board? Or should we leave it connected to the router and then change its address?

Can you fill in the template? We need more information to understand the circumstances. Normally you don't need to do manual copy of .bin and .dtb. You can follow this: https://github.com/open-sdr/openwifi#update-fpga

Normally we connect the board to PC directly via Ethernet cable. But this is standard ip/ethernet thing, you can decide your way.

I don't see where it says to build the FPGA. I followed the instructions, but I encounter an error when running wgd.sh.

cd openwifi root@analog:~/openwifi# ./wgd.sh usage: Script for load (or download+load) different driver and FPGA img without rebog no argument: Load .ko driver files and FPGA img (if system_top.bit.bin exist. 1st argument: If it is a NUMBER, it will be assigned to test_mode. Then load . 1st argument: If it is a string called "remote", it will download driver/FPGA.

The error implies essential issue. In most cases, it is due to some wrong operations.

1. Please fill the issue template.
2. Please describe in details about the exact operation and its output step by step to reproduce this issue. Description should start from you download our SD card img file, and how do you flash it to SD card with all info (OS version, etc, as listed in our issue template).

I need to update my FPGA before this steps ?

raspi-config --expand-rootfs (Only needed when your SD card > 16GB. Run and reboot) ./openwifi/setup_once.sh (Reboot the board. Only need to run once for new board) cd openwifi ./wgd.sh ./fosdem.sh (Use "./wgd.sh 1" to enable experimental AMPDU aggregation on top of 11n) (Use "./fosdem-11ag.sh" to force 11a/g mode)
