LED TX1 SOM

Hello,

We are using the Jetson TX1 SOM (module) with the Leopard TX1 carrier board. We need to drive an LED from our application. Leopard has told us to use the GPIO pin on the SOM directly… where is this PIN located? Has anyone successfully implemented this design?

thanks

Hi, please check the pdf schematic of carrier board, P2597, http://developer.nvidia.com/embedded/dlc/jetson-tx1-tx2-developer-kit-carrier-board-b04-design-files ,connector J21 is the GPIO expander connector, you can choose one GPIO to drive LED.

Refer to this page for detail: https://www.jetsonhacks.com/2015/12/29/gpio-interfacing-nvidia-jetson-tx1/

Thank you for the information and quick replies.

Both replies appear to reference the TX1 dev kit. We are using the TX1 module (SOM) with the Leopard TX1 carrier board:

Leopard has informed us we need to use the GPIO_FLASH_EN pin on the SOM directly. Where is this located?

Is there an alternate solution?

thanks

D7 pin of module connector is FLASH_EN, you should ask Leopard if their board has routed this pin out and if so, how to connect it to your LED.
