Hi Team,

Have anyone tried Ethernet and USB together? I am trying Ethernet with USB VCP example given in example codes of USB. But when i initialise the USB code , My ethernet link broke down . may be some issue with timings ?

Have anyone tried and faced the same issue?

any help will be appreciated.

Thanks,

Dheeraj

Hi,

I have Ethernet and USB Host(HS) together on 100 pin part(f407).

Best to check for pin conflicts. The PHY example code relies on system tick and

own software timers and runs rarely (250 mS is the fastest processing) so there is

not much overload on the CPU if you have both running.

Another idea is to move the init of both peripherals away from implementation

to your main init and check if each works if the other one processing in

the main loop is disabled, but init for both done.
