6 days ago I have some updates:
I made some new changes to the nv-l4t-usb-device-mode-start.sh file:

Hello, I am working on the latest Matrice M3TD drone with dock2 right now and we are trying to establish PSDK connection with the M3TD using Jetson Orin Nano. We are using the PSDK version 3.8. Initially I tried to use DJI_USE_UART_AND_NETWORK_DEVICE and I got an error suggesting that I should use DJI_USE_UART_AND_USB_BULK_DEVICE as DJI_USE_UART_AND_NETWORK_DEVICE is not supported in M3TD. I tried to follow this guide for Jetson Nano. But while doing so I am facing some issues as I couldn't see the devices /dev/usb-ffs/bulk1 and /dev/usb-ffs/bulk2. I searched the internet and found another person facing the same issue. That person tried connecting the E-port's USB-C output to the USB A port instead of the USB-C port and he overcame that issue. But I tried the same and it doesn't work.
here is my nv-l4t-usb-device-mode-start.sh code:
I have modified the path of startup_bulk and I have modified the line with
udc_dev_t186=3550000.usbin line 41 since that threw an error.But this still doesn't work. I need some support to fix this.
