Rpi 4B with RD09

General
1

I am currently conducting 802.11ah and 802.11s tests using MM8108-EKH19 (ML-GT3000, RD09).
As the next phase, I would like to change the main board from the ML-GT3000 to a Raspberry Pi 4b and perform the same tests.
I performed the following steps on Ubuntu 20.

git clone https://github.com/MorseMicro/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
./scripts/morse_setup.sh -i mm8108-ekh01
make menuconfig
*Target System: Broadcom BCM27xx*
*Subtarget: BCM2711 boards (64 bit)*
*Target Profile: Raspberry Pi 4B*
*Kernel Modules → Wireless Drivers → <*> kmod-morse → [*] USB support*
*Morse micro → essentials → [*] morsecli*
*Morse micro → features → [*] morse_mesh11sd*
*Network → WirelessAPD → <*> wpad-mesh-wolfssl*

make -j$(nproc)

When I booted up this image on Rpi4B, nothing showed up in ‘iw dev’.
When I asked copilot, it told me to set ‘enable_wiphy=1’.
However, on the ML-GT3000, it says ‘enable_wiphy=N’.

When I asked copilot further,
it said that this is because the ML-GT3000 generates a virtual interface using a unique method,
and that on the Rpi4B I should set firmware_type to fullmac and enable_wiphy=1.
Is what copilot is saying correct?
If not, what should I do?

Hi @str

Copilot is telling you lies :slight_smile:

We have a shortcut board target for OpenWrt to get you to a functioning configuration with the USB dongle used in the GL-MT3000 - rpi-4-mmeval. Simply run the following steps:

git clone https://github.com/MorseMicro/openwrt.git -b 2.9.3 # specify the branch here to get the release tag :)
cd openwrt
./scripts/morse_setup.sh -i -b rpi-4-mmeval
make -j$(nproc)

No need to adjust anything :slight_smile: .
Note, you are missing the -b from setup script, so it may not have picked up the correct board configuration.

Thank you for letting me know.

I did the following and the menuconfig display returned to its default state.

sudo apt update
sudo apt install -y build-essential git libncurses5-dev gawk gettext unzip file libssl-dev wget python3
sudo apt install -y python3-distutils
git clone https://github.com/MorseMicro/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
./scripts/morse_setup.sh -i rpi-4-mmeval
make menuconfig

rpi-4-mmeval_menuconfig2
rpi-4-mmeval_menuconfig2747×235 39.4 KB

My guess was as follows:

Target System: Broadcom BCM27xx
Subtarget: BCM2711 boards (64 bit)
Target Profile: Raspberry Pi 4B

Am I doing something wrong?

This should be

./scripts/morse_setup.sh -i -b rpi-4-mmeval

Note the -b.

You also don’t need to run ./scripts/feeds update -a and ./scripts/feeds install -a as the -i flag on morse_setup.sh runs this for you :slight_smile:

Thanks,ajudge.

./scripts/morse_setup.sh -i -b rpi-4-mmeval

When I run it, it says that there is no board called “rpi-4-mmeval”.
Is the morse_setup.sh I’m using incorrectly?
Or is some clear operation required on the Ubuntu side?

Oh that’s interesting, I was under the impression it would pick it up as there is a target defined: CONFIG_TARGET_DEVICE_bcm27xx_bcm2711_DEVICE_rpi-4-mmeval

If the script isn’t picking it up, use

./scripts/morse_setup.sh -i -b ekh-bcm2711

which will build a set of bcm2711 based targets based on the configuration in the boards directory.

Dear ajudge:
By changing the following in menuconfig and building, we were able to confirm that it would start up in the same way as MM8108-EKH19. The GUI is also enabled.
Target Profile: Raspberry Pi 4B

Very very thanks!
