Hi all. I set all pins to “high_z” state, but I get only 0, 0, 0, 0 . Pins short to VCC (3.3V). What problem?
io =
tio1 = high_z
tio2 = high_z
tio3 = high_z
tio4 = high_z
pdid = high_z
pdic = high_z
nrst = high_z
glitch_hp = False
glitch_lp = False
extclk_src = hs1
hs2 = None
target_pwr = True
tio_states = (0, 0, 0, 0)
Hi,
Yup that’s the correct way to read the TIO pins. I’ve confirmed the issue; we’re currently looking into a fix and will get that pushed out ASAP.

I think this was just a mismatch between the latest FPGA firmware and the file where that firmware is loaded from (cw1200.py). This should be fixed by the latest commit.

Great! Update firmware and now work fine. Thanks!
This needs to be documented 
https://chipwhisperer.readthedocs.io/en/latest/api.html#firmware-update
Perhaps the python script should include a hardware_type=‘cwpro’ ?
Sorry about that! We added a hardware_type='cw1200' option when we rebuilt the cw1200 fw, but completely forgot to update the docstring as well!
I’ll get that pushed out asap.
