Hi,

 

I want some info on the USB OTG of BF54x processor.

 

Does the USB2.0 OTG/Host Controller works similar to the USB2.0 OTG/Host of BF52x. Want to know whether all the supported features of BF52x inbuilt USB are provided in BF54x Series USB OTG/HOST also.

 

Whether all the anamolies related to USB(documented/Non-documented) in BF54x series are fixed or not?? Is their anything pending ??

 

Whether the BF54x inbuild USB2.0 Host support External HUB & other common class drivers like Mass Storage Class & whether this USB Host Controller supports all type of speed (High/Full/Low)???

 

Thanks in advance.

 

 

With Regards,

 

Peter.

the host controller is the same on both Blackfins, so they of course have equivalent functionality

 

you can visit analog.com/blackfin and read the anomaly sheets to see what is/isnt fixed

 

as clearly documented, hubs are not supported and most likely never will be on these parts

 

USB drivers dont care what host controller is in use -- that's the whole point of having a properly defined stack
