Hello, I have two Orin NX modules and two Orin Nano dev kits, also two NVMe SSD disks. One of the modules flashes successfully with all dev kits and NVMe disks. Another module doesn’t want to flash. Tried through the SDK Manager application and through the console. Flashing process gets stuck at the beginning. Maybe you can help, thanks.

Hi,

did you get anything from UART on the Orin NX module that fails to flash?

No, I found the manual for the Jetson Nano ([https://jetsonhacks.com/2019/10/10/jetson-nano-uart/](https://jetsonhacks.com/2019/10/10/jetson-nano-uart/)). Is it suitable for Jetson Orin NX?

Hi,

the concept should be the same.  
Just make sure you connect the TTL cable to right pins on your module (TXD to RXD, RXD to TXD, GND to GND), and you will have `/dev/ttyUSB0` available on your host.
