Hi at all,
I'm currently planning the support for the FTDI FT2232H and FT4232H with
OpenOCD. They have some new features and I would like to have some
comments for the implementation.
There are two main features:
- Adaptive Clocking: For this feature I would like to introduce a new
parameter for the interface file, e.g.
ft2232_adaptive_clocking {0,1}
- A TCK of 30 Mhz is now possible and that's my main problem. How to
handle this. I thought about three options:
* create a new parameter for the interface file, e.g.
ft2232_device FT2232{C,D,L,H}
* try to implement a sort of autodetect. I currently do not know if it
is possible, just an idea.
* Extend the table of the layouts in ft2232.c with a addional column,
which chip is assembled.
I prefer option 1. What do you think ?
regards
Joern
