Example:
echo "0 20" > rdeeprom : Read 20 bytes of EEPROM data from offset 0
hscfg
This command is used to debug/simulate host sleep feature using
different configuration parameters.
Usage:
echo "<condition> [GPIO# [gap]]]" > hscfg
cat hscfg
where the parameters are,
<condition>: bit 0 = 1 -- broadcast data
bit 1 = 1 -- unicast data
bit 2 = 1 -- mac event
bit 3 = 1 -- multicast data
[GPIO#]: pin number of GPIO used to wakeup the host.
GPIO pin# (e.g. 0-7) or 0xff (interface, e.g. SDIO
will be used instead).
[gap]: the gap in milliseconds between wakeup signal and
wakeup event or 0xff for special setting (host
acknowledge required) when GPIO is used to wakeup host.
Examples:
echo "-1" > hscfg : Cancel host sleep mode
echo "3" > hscfg : Broadcast and unicast data;
Use GPIO and gap set previously
echo "2 3" > hscfg : Unicast data and GPIO 3;
Use gap set previously
echo "2 1 160" > hscfg : Unicast data, GPIO 1 and gap 160 ms
echo "2 1 0xff" > hscfg : Unicast data, GPIO 1; Wait for host
to ack before sending wakeup event
getlog
This command is used to get the statistics available in the station.
