Unable to Flash R36 on Orin Nano 8GB Dev Kit Using External Storage

Autonomous Machines Jetson & Embedded Systems Jetson Orin Nano

Thanks for your information.

I succeeded install R36.2.0 by l4t_initrd_flash.sh.
I can continue the installation by reconnect the USB cable, after USB Gadget was enabled.
It seems possible that the USB Gadget is operating in an incorrect USB device mode before it starts.

succeeded_initrd.log (50.0 KB)
succeeded_capture_initrd_flash_usb_reconnect.txt (153.9 KB)
succeeded_hostpc_kernel.log (9.2 KB)

Details are below:
First, I prepared nv_enable_remote.sh with comments and sleep added to make it easier to see the progress.
nv_enable_remote.sh.txt (8.6 KB)
In particular, the process of searching for a UDC device seemed to be a waste of waiting time, so I changed the process to exit the loop once it is found, just like in R35.4.1.
This reduces the waiting time for ssh access.

for _ in $(seq 60); do
	echo "set_up_usb_device_mode: check UDC device"
-	udc_dev=3550000.usb
-	if [ ! -e "/sys/class/udc/${udc_dev}" ]; then
-		udc_dev=""
+	udc_dev_t186=3550000.usb
+	if [ -e "/sys/class/udc/${udc_dev_t186}" ]; then
+		udc_dev="${udc_dev_t186}"
		break
	fi
	sleep 1
done

Second, once “enable_remote_access()” completed, the USBGadget configuration looked fine to me.

bash-5.1# ip a

At this time, a USB connection error message appeared on the host side before Jetson set the DeviceMode.
[25693.010687] usb usb4-port2: Cannot enable. Maybe the USB cable is bad?

At this time, once I re-pointed the USB cable connected to OTG, the USB was recognized normally, RNDIS and MassStorage worked as expected, and the installation was completed.
