hello parthm,

are you working with Jetson Nano developer kit, or is it a customize board?
may I also know which JetPack release it is. thanks

Hii,thanks for quick reply
i am using jetson nano developer kit and it is not customised, and i am using jetpack version
l4t archive 32.6.1.
i am able to enable spi1 by modifying dtb file.
but how can i enable through expansion header tool.

hello parthm,

is it a production module. which with internal eMMC version. if yes, Jetson-IO doesn’t support with production modules.
please use the pinmux spreadsheet to change the pinmux setting for production modules. thanks
