great. Does the SAM7 have an internal pull-down on nWP? If not, we
should add one, just to be sure the power-up default state is LOW.
pull-down added
I am not familiar with USB buffers? How do they work?
It's not a buffer (just
me not knowing what I do).
It's just and emi filter, replacing the R and C for the USB.
So I don't really see a choice but to have a software-controlled USB
reset option. Once again, we know that this part is working in OpenPCD
0.4 (we had a couple of earlier versions, and they all had some
shortcomings). It's really useful to have both the nRESET as well as
the GPIO controlled usb-pullup (called UDP_PUP) in OpenPCD.
That is the part I never understood in openPCD. What was the purpose of
USB_PUP ?
Now I understand (finally). Thus I did the same as openPCD now.
Waiting for next corrections,
