Hi,
We have our carrier board with nano,now we would like to use Xavier-NX with it.
The debug uart pin are UART2_TXD(236) and UART2_RXD (238).
Our carrier board with nano was working fine at debug uart port.but I got the garbled in my console from xavier-nx.
Hi Karis,
Have you checked the pinmux?
You mean? seems the same.
I mean the pinmux spreadsheet to configure GPIO or SFIO. If you want to enable UART, it has to be SFIO first.
Could you share the step you enable UART on jetson nano? Want to see if anything is not working on NX.
Hi WayneWWW,
set kernel config
CONFIG_USB_SERIAL_OPTION=y
Use USB to TTL Serial Cable,connect to PC and Jetson’s debug Uart pins.
Jetson Nano UART2_TXD → Cable RXD (White Wire)
Jetson Nano UART2_RXD → Cable TXD (Green Wire)
Jetson Nano (GND) → Cable GND (Black Wire)
Use puTTy tool, setting serial port and speed (115200) of Win10
Check console.
Karis
I will check it this afternoon. Thanks for reporting this.
Hi WayneWWW,
Any update? Thanks.
Karis
Hi Karis,
I just checked with NX on my nano devkit and it has the uart log.
Could you take a photo of your carrier board with usb-ttl cable connected?
Hi WayneWWW,
Sorry! My mistake,update the right pin define of TTL.
Cable TXD (White Wire)
Cable RXD (Green Wire)
Cable GND (Black Wire)

Hi,
Are you using jetson nano devkit?
Hi WayneWWW,
No our carrierborad.
Hi,
Could you try your module to nano devkit and test the function first?
Hi WayneWWW,
We resolved the problem.Thanks!
Hi,
How about sharing your solution here for others to take as a reference?
Hi WayneWWW,
We use another TTL cable,the output is the uart log not garbled.
