5 years ago This look like the same issue fixed in 6b33f29. I tried the following sequence on the head of dev branch, and it succeeded 10/10 times. `modprobe wilc_spi wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wilc_wpa_supplicant.conf &
killall wpa_supplicant rmmod wilc_spi`

5 years ago That works OK but is not what I listed in the reproduction method. You're also not using an SDIO connected device.
Please try with what I posted, not something else.
modprobe wilc-sdio; \
ifconfig wlan0 up; \
/usr/sbin/wpa_supplicant -Dnl80211 -iwlan0 -c /etc/wpa_supplicant.conf -B; \
rmmod wilc-sdioWhich driver commit is the latest wilc_demo up to? There is no version numbering to be able to tell.

5 years ago The latest demo maps to release 15.01 release as per the commit message. This release is tagged on the driver, firmware and linux-at91 repos, and it doesn't have the fix i'm pointing to.
I'm not expecting much difference between spi and sdio since the warning is triggered from the cfg layer while closing the net interface, so the bus shouldn't differ much.

5 years ago Using -dev "updated demo binaries for release 15.2 RC1" is the commit message so no it doesn’t give the driver version. The master driver is much too old/broken to use.
Have upgraded the firmware binaries to 15.2 RC3 (build 10924) firmware.
Seems to crash every time on the second loop when modprobing module:
# cat wifitest.sh
#!/bin/sh
while true; do
modprobe wilc-sdio
sleep 3
ifconfig wlan0 up
sleep 1
/usr/sbin/wpa_supplicant -Dnl80211 -iwlan0 -c /etc/wpa_supplicant.conf -B
sleep 20
rmmod wilc-sdio
sleep 1
killall wpa_supplicant
sleep 5

---[ end Kernel panic - not syncing: Fatal exception in interruptI didn't get your comment clearly
Using -dev "updated demo binaries for release 15.2 RC1" is the commit message so no it doesn’t give the driver version
the driver version used for this commit is 15.2 RC1 from the dev branch.
Did you update the driver to the head of t he dev branch as well, or only the FW? please note that the fix I was referring to in my comments is in the driver.
I had your script running for ~30 mins, where it did 70 cycles, and I couldn't see the failure. wifi_init_logs.txt

5 years ago @ShonkyCH , are you still seeing this problem?

5 years ago I have also been testing for this issue yesterday and again today. Yes, there is still an issue with this sequence. More in a few hours.... Summary:

5 years ago Yes we are still seeing this. It seems more of a problem when the module is receiving traffic e.g. flood ping it or do a constant UDP iperf from another machine to the module so it's always receiving packets.

5 years ago I had the similar experience with trying to integrate ATWILC1000 with a Raspberry Pi CM3+. I could see the kernel oops saying null kernel reference. When I dig deeper I could see this oops was happening when CMD52 read error occurs. I had wired the two dev kits with wires and I thought this could be a signal integrity issue as my sdio clock was running at 50MHz, So I reduced the sdio clock to 25MHz just to test and it solved the problem. I have tested the driver with iperf, flood pings, wget large files and it seems to hold.

I think the driver is not gracefully handling a CMD52 read failure. This was failing (in my case) in kernel thread "K_TXQ_TASK " and executing wilc_wlan_txq_remove_from_head () function.

@ShonkyCH I have the same problem. Did you solve it?

We never had a 100% reliable way to reproduce it - just it seemed that pulling the module whilst receiving packets caused it. I would say it's better in newer versions but can't 100% guarantee it's fixed. Definitely try the latest release if you haven't already.
We have spent way too much time chasing issues with driver and firmware on this thing, we're just not in a position to burn more time on it whilst it's largely working.
Hardware: SAMA5D4Xplained dev board + ATWILC1000-SD (rev 4) dev board
Software: wilc_demo 15.2RC1 from: https://github.com/linux4wilc/wilc_demo/tree/009b36048d18ffb64b2140eeecd0194cc21cbfd4
There is no "AP" access point in the vicinity i.e. the unit has nothing to connect to. There are quite a few other APs around though as you can see in the log.
Steps to reproduce:
Repeatable every time. Yes this is a somewhat harsh test, but the driver shouldn't be taking down the whole system.
I should note that the wpa_supplicant step is required. Without that step it doesn't crash.

Second stack trace comes a few seconds after the initial one.
