Hi!

I am only getting ~155 Mb/s write speed from the USB port on the RedPitaya. Is it not possible to get somewhere close to the full 480 Mb/s of USB 2.0 on the RedPitaya? What USB PHY is used on the board?

I am using Petalinux. Could it be that I am missing some setting?

Any input would be appreciated!
Thank you

Hello std_logic,

I will check with the team and let you know.

The USB PHY manufacturer number is:
USB3320C-EZK

Thanks alot!

Theoretically it should all be capable of 480 Mb/s or 60 MB/s.

But even here on the Xilinx page only 25 MB/s are given as an example in host mode. Could of course be a limitation of the USB device in their case, who knows.
