![]() I don't know the significance of that - references to "linux-devkit" on the web seem to be TI-centric, and I am naive in rebuilding kernels and what-have-you. I'd rebuild it, except it seems to have come pre-built in the Processor SDK under "linux-devkit", source code not supplied. Meanwhile, this page /./NL80211_TESTMODE.html suggests that this "testmode" thing should not be in our build of wpa_supplicant. I cannot even begin to fathom what that might be, and I can't google up any references that enlighten me. Trouble is, that requires a bunch of dependencies and I'm really uncertain how to get them in place and consistent with the build on this board.Īnother possibility would be to fix the problem so that testmode "membership" does work. So I thought I could build v2.4 of wpa_supplicant and side-step the issue. ![]() In any case, I don't know what "testmode" is, and whether we need it (our design brief is pretty straightforward: connect to a network of known SSID/passphrase). That driver seems to be associated with the related "hostap" project, but I don't know how the two intersect. What is not clear to me is how that branch could make it into the binary that is on my board (it is, grep finds the error message in the binary at /usr/sbin/wpa_supplicant on my device). However, there is a branch of the driver hosted at /./f19c3bbaf916c25344c4bf43e24783c809071dca that does. I've downloaded both versions 2.1 and 2.4 of wpa_supplicant (main branch), and the source code does not include this feature. The key failure point seems to be "Could not add. Wlan0: cancel_sched_scan called when no sched scan ![]() Wlan0: P2P: Station mode scan operation not pending anymore (sta_scan_pending=0 p2p_cb_on_scan_complete=0) Nl80211: Could not add multicast membership for testmode events: -2 (No such file or directory) Initializing interface 'wlan0' conf '/etc/wpa_nf' driver 'nl80211' ctrl_interface 'N/A' bridge 'N/A'Ĭonfiguration file '/etc/wpa_nf' -> '/etc/wpa_nf' Random: Trying to read entropy from /dev/random The problem is that when we try to start wpa_supplicant against our USB WiFi dongle, which is based on the Realtek RT5370 device, the driver generates the following error log and will not wpa_supplicant -B -i wlan0 -c /etc/wpa_nf -dd -Dnl80211 ![]() ![]() In any case, this problem seems to be around the nl80211 driver built into wpa_supplicant, so I doubt the board details are relevant. The board is based on a Beaglebone Black, but lacks HDMI, ethernet. We have got as far as a running Linux system on our bespoke AM335x board. ![]()
