Hi Guys, I'm further with getting my stuff working on the CAMBRIA xscale boards, but now see this ath1: ath_legacy_rxbuf_init: bus_dmamap_load_mbuf_sg failed; error 12 error when trying to configure a second or third atheros board. Below is the script run with -x with its output. The same is working fine on an Avila board. The Avila has 64M RAM and the CAMBRIA 128M. The userlevel code is the same for both and in trying to see if it is something missing in the kernel config, I have made a common kernel config file with all the common AVILA and CAMBRIA configs and then included that in a new AVILA and CAMBRIA config file. That gave the same result. The output is from a 2 week old -current/head. ############################## ~ # uname -a FreeBSD 11.0-CURRENT FreeBSD 11.0-CURRENT #5 r267954M: Fri Jun 27 14:49:04 SAST 2014 jhay@dolphin.meraka.csir.co.za:/usr/obj/arm.armeb/snaps/arm/11-tst/src/sys/SMALL-CAMBRIA arm ~ # /root/do-wlans + crflags='wlanmode adhoc' + dbgval=0x20000500c + ifconfig wlan0 create wlandev ath0 wlanmode adhoc wlan0: Ethernet address: 00:80:48:4f:24:ea + ifconfig wlan0 inet 10.0.1.1/24 channel 36 ssid ptabb bssid 05:05:ca:fe:ba:be + sysctl dev.ath.1.debug=0x20000500c dev.ath.1.debug: 0 -> 8589955084 + ifconfig wlan1 create wlandev ath1 wlanmode adhoc wlan1: Ethernet address: 00:80:48:4f:24:da + ifconfig wlan1 inet 10.0.2.1/24 channel 40 ssid ptabb bssid 05:06:ca:fe:ba:be ath1: ath_init: if_flags 0x8803 ath1: ath_stop_locked: invalid 0 if_flags 0x8803 ath1: ath_legacy_rxbuf_init: bus_dmamap_load_mbuf_sg failed;
