I want to test 40 pin header hardware without external devices,Does have any ideas about it.
Thanks to veryone
There is so much in that header I doubt anyone knows where to start. You might want to narrow the question down with something more specific, or what you want to accomplish.
There are spi \ i2c \uart\gpio\i2s in header, i want to test those pins work or not on carry board by software
there’s a python library that enables the use of Jetson’s GPIOs,
please refer to https://github.com/NVIDIA/jetson-gpio/tree/master/samples for samples to test all pins.
