I am running Allstar on a Raspberry Pi 3B+ and both Allstar and Echolink are connecting. I am trying to convert an IRLP node to run Allstar and hope to use the IRLP board for PTT and COS. When I set up simpleusb.conf for using the GPIO
[usb_53017]
; IRLP board support
pp3 = ptt ; out0, out1 or ptt
pp11 = cor
;
pp4 = out0 ; pins 4,5,6 are AUX 1,2,3, default off
pp5 = out0
pp6 = out0
hdwtype=0
rxboost=0
txboost=0
rxctcssrelax=1
txctcssdefault=100.0 ; Disregard this CTCSS section unless you are using discriminator
rxctcssfreqs=100.0 ; audio and injecting PL from the USB FOB directly into the modulator.
txctcssfreqs=100.0
;rxctcssoverride=0 ; If using a typical IRLP setup - muted, filtered receive audio and injecting mic audio
; into the mic jack, you’ll want to do your PL encode and decode
;carrierfrom=dsp ; in the node radio itself, not via Asterisk DSP.
ctcssfrom=no
carrierfrom=ppinvert ; use either pp or ppinvert
;carrierfrom=pp ; depending on the cos logic of your radio
rxdemod=speaker
txprelim=no
txlimonly=no
txtoctype=no
txmixa=voice
txmixb=no
invertptt=0
duplex=0 ; 0=half duplex 1=full duplex
rxondelay=0
rxnoisefiltype=0
eeprom=0
I keep getting the following error when I restart asterisk.
[Nov 16 17:09:01] ERROR[4950] chan_simpleusb.c: Cant get io permission on IO port 0378 hex, disabling pp support
Any thoughts on why I am unable to access the IO port?
Thanks!
