I have a FPGA with FX3 SDK to collect signal samples and transfer data to tk1 through usb. And I have enabled the USB port as 3.0 in the L4T 21.3 release by editing usb_port_owner_info to 2 in /boot/extlinux.conf.
But when I connect the FPGA to tk1 and download the firmware into the FX3’s RAM, it’s detected as usb2. However, when I do the same thing on my laptop, it’s detected as usb3.0.
Can anyone figure out where the problem exists?
Thanks for your private or public comment/suggestion.
