Linux/AM3358: OTG speed problem

Jackdonald

Part Number: AM3358

Tool/software: Linux

Hello,

We are building a board with AM358 and we have a limitation with USBOTG : we are limited to 33 Mbits/s (far away from the usb 2.0 speed expected). Is here any limitation? something to add / modify on linux debian.

Thanks for your answers !

more details :
we run iperf client from the board
1.- From board to USB port, we connected a wifi : we can reach more than 70Mbits/s
2.- BUT From the board to a computer trough USB otg we only reach 33Mbits/s

Hi,

Debian Linux is not supported by TI. This is a community build supported on www.beagleboard.org

Hi Jack,

Can you do the performance test using the USB drivers provided in the TI processor Linux SDK?
http://www.ti.com/tool/PROCESSOR-SDK-AM335X

With the beaglebone black you can easily test with both Debian distro and TI SDK.

You can look at processor Linux SDK 5.x for Linux Kernel 4.14 and Processor Linux SDK 4.x for kernel 4.9.

Thanks for your understanding.

Hi, I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). thanks.
