.SH NAME
scsiloop \- Tool for testing the PiSCSI board with a loopback adapter installed
.SH SYNOPSIS
.B scsiloop
[\fB\-L\fR \fILOG_LEVEL\fR]
.SH DESCRIPTION
.B scsiloop
Performs a self-test of the PiSCSI hardware to ensure that the board is functioning properly. In order for this tool to work, a special loopback cable MUST be attached to the PiSCSI SCSI connector.
In addition to testing the GPIO signals, scsiloop will perform a self-test of the hardware timers that are built into the system on a chip (SoC).
The loopback connections for the DB25 connector are shown here:
