Hi Guys,
We are using AM335x custom board + wilink8 chipset with latest SDK ti-processor-sdk-linux-am335x-evm-03.00.00.04/ from ti website, i was able to load all module even added new conf file with firmware checked, we intend to use 2.4Ghz, we ran ap_start.sh, it enabled SSID sitaraAP(default), but we got nat table error,
>>" iptables v1.6.0: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
>> Perhaps iptables or your kernel needs to be upgraded."
as it is latest kernel, by default wl18xx module is inbuilt, so we don't need to load any module but still i checked lsmod all wifi related modules were present, except wlcore_sdio, when i did modprobe i got error saying modules is already present.
i checked cat /proc/interrupts i got wl18xx irq. i have checked all 4 datalines, clk, cmd, en & irq lines everything is present passing required voltage,clock signal, connected 26MHz. checked that too on board working properly.
well even checked driver_state, you can see
cat /sys/kernel/debug/ieee80211/phy0/wlcore/driver_state
channel = 3 (AP)
tx_blocks_available = 44
tx_allocated_blocks = 0
tx_allocated_pkts[0] = 0

chip.fw_ver_str = Rev 8.9.0.0.48
chip.phy_fw_ver_str = Rev 8.2.0.0.232
recovery_count = 0
even after doing all these i'm not getting any signal, checked with wifi analyser tool to see signal strength nothing came into picture.
tried as station but no success, same issue nothing came.
when passed # iw wlan0 scan
>>>>>>>>>>>>>>>>>>>Nothing came on screen
# iw event -t -f &
# iw wlan0 scan
//got message scanning and some 2.4GHz frequency other that nothing, no ssid
Does anybody has any idea or if required more information please do free to contact.
regards,
Ganesh
