Hi, We have 2 USB 2.0 ports straight coming out from SOM module, even these 2 are not working, when we connect mouse or keyboard. Even power not coming in mouse or keyboard. There are 2 more USB 2.0 ports, which we have customized from PCIe lines to USB using a IC on our carrier board, even t…

You may have signal integrity issues. The different SSDs may have better signal to noise of timing adjustments than others. If they connecting at 3.1 speeds you could try forcing the interface to USB 3.0 speeds in the DT and see if they can connect at a slower speed. To find the speed of the conn…

[image] WayneWWW: I am not sure what is your point to ask me read @BigDon ’s comment here as I already told you the same thing here… since you told flash failure would happen as below, I told that. Just for an experiment. I know it would make flash failure but this is not the point to concern…

We were able to see NVidia CORP being listed with lsusb command on the host PC, when we set to recovery mode It has nothing to do with your hardware design or any device tree. It is a nature of recovery mode. When you put the board into recovery, it is just set jetson to be USB device. This i…

[image] WayneWWW: It turns out that even hardware signal seems not stable enough that your host mode seems not always stable. For the -71 error, please check the tuning guide. Nothing for the device tree for now. Will inform this to our hardware designer to rectify. Thanks.

There is no such method. Your port design does not support to run a true OTG mode. Already explained in previous post. Later Jetpack7 has trick to flash different DTB to the board. But for Jetpack 6, it is not present.

Here in JP 6.0 after doing final flashing, cannot we manually copy the master DTB file to /boot/dtb/kernel-tegra-3737-0000-xxxxxx.dtb and reboot the unit. Wont this work out? This would work. But I am uncertain if your end user would expect that they have to manually do this after their first fl…

Hi,

we have this point of concern now.

After making USB_2_0( flashing port) as HOST mode from OTG , flashing of NVME is no more working. It is throwing No Known UDC device found in the serial console during flashing and USB getting timed out error finally similar to to below link:

Please let us know what is solution for this.

We need use this port both for flashing NVMe( in OTG mode) and later it should work in host mode as normal USB 2.0 port.
