Listdevicenames output
Based from the output of --devicenames, you can decide if you must 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:~# pltool -listdevicenames
0x0 : CPLD1
0x3e : CPLD2
0x3e : CPLD3
0x3e : CPLD4
0x0 : SMF_FPGA
Read output
root@dell-diag-os:~# pltool --read --devname=CPLD4 --dev=0x3e --reg=0x2
SW_SCRATCH : offset 0x02 = 0xde
7: 0 SW_SCRATCH = de
root@dell-diag-os:~#
Write output
root@dell-diag-os:~# pltool --write --devname=CPLD4 --dev=0x3e --reg=0x2 --val=0xff
Test output
root@dell-diag-os:~# pltool --test
