listdevicenames Output
Based from the output of --devicenames, you can decide if you need to use the --devname= option in
the read or write functions. You can access CPLD1 being at deviceaddress 0, using the register value for
the register you want, such as:
root@dell-diag-os:/etc/dn/diag# pltool --read --dev=0 --reg=0x100
CPLD_VERSION : offset 0x100 = 0x3
7: 4 MAJOR_VER = 0
3: 0 MINOR_VER = 3
CPLD2-4 having the same device address, needs to use the devixcename as such
root@dell-diag-os:/etc/dn/diag# pltool --read --devname=CPLD3 --reg=0x10
zQSFP_RESET_CTRL0 : offset 0x10 = 0xff
7 zQSF20_RST = 1
6 zQSFP19_RST = 1
5 zQSFP18_RST = 1
4 zQSFP17_RST = 1
3 zQSFP16_RST = 1
2 zQSFP15_RST = 1
1 zQSFP14_RST = 1
0 zQSFP13_RST = 1
