Hi everybody,

did anybody tested performance with sending some file from USB flash drive with FatFS using USB ULPI to the ethernet LAN ?

what is highest achievable speed ?

i measured roughly 94MBit/s using iperf but it's not an overall performance ...

i tried to receive file but i got some strange errors on USB so the transfer was interrupted after roughly 10kBytes - 20kBytes of file ... :(
