Hi Peter,
<snip>
Can you please describe your use case?
Andrzej
I would like to change parameters for function driver through configfs, below is the example for ncm and f_sourcesink cases,
thanks.
if [ "$FUNC" == "ncm" ]; then
mkdir functions/$FUNC".0"
ln -s functions/$FUNC".0" configs/c.1
echo 10 > functions/ncm.0/qmult
echo "12:a5:cf:42:92:fd" > functions/ncm.0/host_addr
echo "5e:bc:ca:27:92:b1" > functions/ncm.0/dev_addr
fi
if [ "$FUNC" == "ss" ]; then
cd /sys/kernel/config/usb_gadget
cd g1
echo "0x0525" > idVendor
echo "0xa4a0" > idProduct
export FUNC="SourceSink"
mkdir functions/$FUNC".0"
ln -s functions/$FUNC".0" configs/c.1
cd functions/$FUNC".0"
echo 1 > pattern
echo 1 > isoc_interval
echo 1024 > isoc_maxpacket
echo 2 > isoc_mult
#isoc_maxburst
echo 1024 > bulk_buflen
echo 16 > bulk_qlen
echo 16 > iso_qlen
fi
Peter
I think I don't quite understand the problem: just postpone issuing
ln -s until after echo <something> > <configfs attribute>.
