[BUG] RaspberryPi-Pico-W is not getting WiFi with Pi Pico SDK 2.0

[UAV-Pilot]

Description / Steps to reproduce the issue

Except getting the latest Pi Pico SDK 2.0, the rest is the same as #7475, which is closed now.

Similar to the errors in #7475, the following errors occurred:

I set SSID and passphrase in menuconfig, and also tried to set them in nsh.

nsh> renew wlan0
ERROR: netlib_obtain_ipv4addr() failed
nsh> ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 at DOWN mtu 5nsh>
nsh>
nsh> ifup wlan0
ifup wlan0...Failed

ChatGPT suggested to set mac address:
ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX (e.g., 28:CD:C1:0A:38:9A)
but got error:
nsh: ifconfig: argument invalid

nsh> wapi show wlan0
wlan0 Configuration:
IP: 0.0.0.0
NetMask: 255.255.255.0
nsh> wapi scan wlan0
nsh> wapi scan_results wlan0
nsh> ifup wlan0
ifup wlan0...Failed

Besides this firmware issue during setup, along the way I encounter other issues as shown in comments below:

1. When not set during menuconfig, SSID and passphrase entered manually in wapi commands disappeared after reboot
2. ifconfig did not output ip address, etc.
3. ifup wlan0 returned message OK which was misleading when wlan0 was not connected and not up running correctly

On which OS does this issue occur?

[OS: Linux]

Download the BINARY firmware file from this link: 43439A0-7.95.49.00.combined ~220K

Make sure the configuration file variable points to the correct firmware file:
CONFIG_CYW43439_FIRMWARE_BIN_PATH="${PICO_SDK_PATH}/lib/cyw43-driver/firmware/43439A0-7.95.49.00.combined"
When compiling, the cyw43439.firmware.image file is created, and it’s the same as firmware/43439A0-7.95.49.00.combined. Ensure the paths and files match during the build, especially in:
boards/arm/rp2040/common/src/cyw43439.firmware.image
prebuilt firmware nuttx.uf2.zip

@darwinbeing Thanks a lot for your quick help! With that firmware, I got wifi working on pi pico W with SDK 2.0.

Besides this firmware issue during setup, along the way I encounter other issues as shown by the following commands:

1. When not set during menuconfig, SSID and passphrase entered manually in wapi commands disappeared after reboot
2. ifconfig did not output ip address, etc.
3. ifup wlan0 returned message OK which was misleading when wlan0 was not connected and not up running correctly

Note: for the following session, SSID and passphrase were not set from menuconfig.

I see if there is no firmware file present, then the firmware file is initialized with the text "dummy" at boards/arm/rp2040/raspberrypi-pico-w/src/Make.defs line 53.

Did the firmware file used to be generated? Maybe we can incorporate that generation back into the build system, or instruct users on how to build the firmware? This should at least be documented somewhere versus the current documentation which just instructs the firmware repo to be cloned.

[linguini1]

It appears the new firmware file actually allows the blob binary to be included as a C variable instead of requiring the assembly instruction to include the binary.

Maybe we could update the boards/arm/rp2040/common/src/rp2040_firmware.c file to do that? I'll look into it. It would also be good to add a warning for the missing firmware file instead of silently making a dummy file.

Convert WiFi binary firmware for W43439 module to C array format
w43439.patch
OR
w43439.patch

[linguini1]

This patch works in the sens that ifup wlan0 is now returning okay, but it does not work when I try to renew wlan0.

nsh> renew wlan0
ERROR: netlib_obtain_ipv4addr() failed
