Can someone help us to verify USB FileSytem speed?

As we tested here
SD: 500~1MB / Read, Write
USB: 2M~3.4MB / Read, Write

SD looks normally, but USB is weird. We tried few USB still give same values.

as the USB speed goes up without reason, we don’t want it is dropped in next release “without reason”.


Are you complaining that USB is too fast? :grin:

Why not share your example that we can run to rest speed the same what you are?

Is USB host still the slower 12 megabits per second?

Correct. 480mhz requires an external PHY and a lot of pins, like 10. We are still evaluating of we want to support that.

Advanced processors have that built in but not smaller micros.
