[ts-7000] TS-7260 DIO issues?

[Don Tucker <>]

Using TS's little script,

ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7260-linux/binaries/ts-scripts/ts7xxx.subr

I attempt to toggle the output voltage of DIO0 through DIO4 and see no
change.  I.e.,  after running the shell (export model=2, .
./ts7xxx.subr), I do:

dio_dir_set X 1
dio_data_set X 0
dio_data_set X 1

for X=0 through 4, and the voltage remains the same at 3.3V.  If I try
the same thing on DIO5 through DIO7, the voltage will toggle between
3.3V and 0V.

Has anyone else seen this behavior, or is it an obvious indication of
faulty hardware?  I am getting no response from TS's tech support.
