ZCU 104 : USB CDC class unable to detect

Jump to solution

Hi ,

I am trying to connect a micro usb IMU sensor to Zcu 104 eval board working on petalinux. In a Linux PC the same IMU sensor is getting detected as CDC data class to a ttyACM device and i tried the same thing here to include CDC class in petalinux by following the below link

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841624/Zynq-7000+AP+SoC+USB+CDC+Device+Class+Design+Example+Techtip

after booting the board with the generated image. My USB port on the Zcu104 cannot power up the IMU sensor that is connected to it .

My target is to transmit IMU data(connected to Zcu104 through USB) countinuously to Zcu104 and read data received .

Can some one help me resolving the issue ?

Please correct me if my approach is wrong.

 

Thanks,

Sai

HI @suddala.s 

ZCU104 board does support only HOST mode and NOT the USB device mode.

So you canot use the cdc class.

Refer this user guide (section:USB 3.0 Transceiver and USB 2.0 ULPI PHY ) :https://www.xilinx.com/support/documentation/boards_and_kits/zcu104/ug1267-zcu104-eval-bd.pdf

 

Thanks & regards
