Hello all,

This is my first post and new user of the Solidrun som modules. I have a RZV2L Rev1.1 module and am having a hard time toggling pin 43 of the J5001 connector. I believe GPIOP9\_1 works out to be gpio257. Right now:

```auto
echo “257” > /sys/class/gpio/export //Works without error but

```

```auto
echo “out” > /sys/class/gpio/gpio257/direction //Fails giving the error -bash: /sys/class/gpio/gpio257/direction: No such file or directory

```

```auto
echo “1” > /sys/class/gpio/gpio257/value //Never gets to run

```

If anyone can help it would be great and thank you.
