Firstly, the USB view does NOT show the OHCI registers!
This makes debugging my host application rather difficult.
I had to write code to copy these registers to a 'dump' region.
The USB setup registers (on LPC1778) has upto 5 separate clocks to enable.
Unless ALL of these clocks are selected, the USB peripheral view 'collapses'
complaining about an access violation at 2008C204.
Also, a memory view on the register space (2008C000) shows '??'s even when
all clocks are enabled.
NB: Code that reads individual (appropriate) USB registers works perfectly.
This is increadibly sloppy. Depending on the application, we configure for
one of device, host, or OTG.
There should be separate USB view for these cases (to avoid usless clutter)
and they should be viewable when only the relevant clocks are enabled.
Comments please.
Regards, Mike
