We still have problem to change USB3 to compliance mode by following the tuning guide.
We have a customized carrier board and the USB 3 port w/o hub.
Due to the previous created topic as below is closed, we create a new topic.
Update more information below.
The USB3 could be changed to compliance test mode by the command, as the USB3 with a device.
The USB3 could not be entered to compliance test mode by command, as the USB3 without a device. (Doing SI test, without a device connected.)
Also, we have to test SI now and Jp4.6.1 is not ready yet.
Thank you for any advice,
Which jetpack version is in use now?
Jetpack4.5.1 usb firmware has problem so that it cannot run compliance mode.
When is Jp4.6.1 ready?
Is it possible to use another usb firmware of different JP version？
There is no jetpack4.6.1. I mean rel-32.6.1 which is jetpack4.6.
Thank you for your prompt support.
Due to it takes time to modify BSP for customized carried board, is it possible to use jp4.6 USB firmware on Jp 4.5.1 for testing?
Yes, you need to replace the firmware in initrd and reflash the board.
mkdir initrd; cd initrd;
sudo gunzip -c ../l4t_initrd.img.orig | sudo cpio -i
sudo cp ../xusb_sil_prod_fw-new lib/firmware/tegra19x_xusb_firmware
sudo find . | sudo cpio --quiet -H newc -o | sudo gzip -9 -n > ../l4t_initrd.img
Thank you so much.
We will test it.
