Hello, I am using the Olimex OLinuxino and I find a constant noise at about 866.725MHz or thereabout in every board. While low, at -100dBm, when using it with IoT radios this is the band in India and it is quite a pain in applications requiring high sensitivity. This particular board had it pretty nasty at -86dB. I have tried with changing the DDR frequency as well as the CPU clock, however this nuisance refuses to go away. What can be done to get rid of this noise ? I have tried multiple boards -- Olinuxino (multiple), Marsboard, but each has some noise in exactly same band near 866MHz. Please advise.

Hello, was this resolved ? -- I faced same behaviour.

Hello All, What do I have to do in order to get Armbian on the Marsboard A20 SOM Thanks,

When I build for Olimex-A10 with the sunxi I2S drivers enabled, build fails. Without this driver, its building/ working fine without issues. I am compiling with 3.4.x and with Jessie. I tried compiling it even as a module but with same result. the lines just before the failure are pasted below: " In file included from drivers/staging/wlan-ng/prism2usb.c:5:0: x x drivers/staging/wlan-ng/prism2fw.c: In function âwriteimage.constprop.37â: x x drivers/staging/wlan-ng/prism2fw.c:1115:1: warning: the frame size of 4240 bytes is larger than 2048 bytes [-Wframe-larger-than=] x x } x x ^ x x LD [M] drivers/staging/usbip/usbip-core.o x x LD [M] drivers/staging/usbip/vhci-hcd.o x x LD [M] drivers/staging/usbip/usbip-host.o x x In file included from drivers/staging/wlan-ng/p80211netdev.c:91:0: x x drivers/staging/wlan-ng/cfg80211.c: In function âprism2_scanâ: x x drivers/staging/wlan-ng/cfg80211.c:404:22: warning: ignoring return value of âcfg80211_inform_bssâ, declared with attribute warn_unused_result [-Wunused-result] x x cfg80211_inform_bss(wiphy, x x ^ x x LD [M] drivers/staging/wlan-ng/prism2_usb.o x x LD drivers/staging/built-in.o x x LD drivers/built-in.o x mqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqj [ error ] ERROR in function compile_kernel [ common.sh:236 ] [ error ] Kernel was not built [ @host ] [ o.k. ] Process terminated " Any pointers on what can be the reason here ?
