PCIE WiFi module driver crashes on Nano but not on TX1

I have a Laird ST60-2230C-PU Wi.Fi module that I’ve verified is fully working on a Jetson TX1 (able to host access point and serve data over WiFi at 200Mbps).

When I connect this module to my custom Nano SOM carrier board I am able to enumerate the device over PCIE and install the drivers, the same way as I do for the TX1, but when I actually try to connect to or host an access point there is a kernel oops/panic:

I see the crash is related to a function in the module’s WiFi driver ([] mwl_pcie_rx_recv+0xb8/0x4b8 [lrdmwl_pcie]), has anyone run into similar crashes on the Jetson Nano for a kernel driver that worked on the TX1? Could anyone provide some suggestions on what to check?

The kernel image is very nearly the same, I am testing with L4T 32.2.0 on the TX1 and L4T 32.2.1 on the Nano. I’ve verified the M.2 slot works fine with the Intel 8265 WiFi card. I guess a device tree configuration difference between TX1 and Nano might be causing the crash?

I am currently unable to test this module on the NVIDIA Nano devkit carrier board due to device not enumerating under PCIE.

For reference here are my approximate instructions for getting the module to work on the TX1:

# Download driver source from : https://github.com/LairdCP/Sterling-60-Release-Packages/releases/download/LRD-REL-7.0.0.84/backports-laird-7.0.0.84.tar.bz2 
# Download module firmware files from: https://github.com/LairdCP/Sterling-60-Release-Packages/releases/download/LRD-REL-7.0.0.84/laird-sterling60-firmware-pcie-usb-7.0.0.84.tar.bz2 
# Download page for other packages: https://github.com/LairdCP/Sterling-60-Release-Packages/releases 
# Prepare kernel sources on TX1 (to get around build error):
sudo -s
apt install git
# copy source_sync.sh script to /usr/src from nvidia's L4T packages or from sdkmanager project folder
cd /usr/src && ./source_sync.sh -k tegra-l4t-r32.2.1
unlink /lib/modules/$(uname -r)/build
ln -s /usr/src/sources/kernel/kernel-4.9 /lib/modules/$(uname -r)/build
cd /lib/modules/$(uname -r)/build
cp /proc/config.gz .
gunzip config.gz
mv config .config
make prepare
make modules_prepare
exit # end sudo -s

# Extract driver source to a folder on device
# See build instructions for source from : https://connectivity-staging.s3.us-east-2.amazonaws.com/s3fs-public/2018-10/Software%20Integration%20Guide%20-%2060%20Series.pdf
# shortcut instructions:
# cd to driver source directory
export CROSS_COMPILE=aarch64-linux-gnu-
export ARCH=arm64
make defconfig-lrdmwl
make -j4

# add two lines to /etc/modprobe.d/blacklist.conf:
blacklist mwifiex_pcie # disable default marvell wifi driver module
blacklist bcmdhd   # disable broadcom wireless (testing on TX1)

# Add pcie_aspm=off to kernel boot args in /boot/extlinux/extlinux.conf to resolve pcie kernel error message 
APPEND ${cbootargs} pcie_aspm=off quiet

# reboot system, open terminal, cd to driver source directory:
sudo -s
modprobe -r cfg80211 # in case it's been installed, need to replace with built version
insmod ./compat/compat.ko
insmod ./net/wireless/cfg80211.ko
insmod ./net/mac80211/mac80211.ko
insmod ./drivers/net/wireless/laird/lrdmwl/lrdmwl.ko
insmod ./drivers/net/wireless/laird/lrdmwl/lrdmwl_pcie.ko

We will check this issue. Thanks for report.

For reference here is full dmesg from boot, including insmod of modules, and finally crashing on starting hostapd or wpa_supplicant

Thanks for the fix, no more crashes! Have working driver now, first m.2 wifi card I’ve found to be working on Jetson Nano (besides Intel)
