Posted on July 11, 2011 at 10:50Good question, would be nice to know. But until then, there is a solution:
The OTG FS controller in the F2XX is nearly identical to that in the the F105/F107. Therefore it is possible to use the USB Lib 3.3.0 with the F2XX. (#define STM32F10X_CL).
The only thing that will cause problems is, that NOVBUSSENS in GCCFG has to be set when VUSB is not connected to PA9 (which is the case on most Non-USB-Host boards).
My self written very basic USB host is now working, too. In Forced Host mode I did not discover any difference in the registers/bits between F105 and F205, only some different behaviour when halting a channel. (Maybe my fault). So I think it should be possible to use the ST USB Host lib, too.
But: This will not work with the
OTG HS controller in the F2XX. The differences are much bigger here, one could try to adapt the code, but IMHO this will be a lot of work. So I think, here it will make much more sense to wait for the official solution from ST (at least if it can be expected in the next few months...)
