Some of us are not part of a large organization with a staff of engineers. I’ve been doing embedded design for a very long time but am by no means a Linux programmer expert on device drivers and such. So is it really that much trouble for nVidia to provide basic documentation to make their customers life just a wee bit easier?
I spent a long time just trying to connect the TX1 development kit debug UART to another computer using putty… a task I’ve done many many times. ‘dmesg | grep tty’ lists no less than 5 available devices and of course ttyTHS2 was the correct one AND last one that I tried. Someone at nvidia knew this so why do I have to find out this information empirically? Now I want to use the SPI1 device on J21. Looks like I have to write my own driver and compile my own kernel based on an alternate device tree… Really? you can’t make that available to help get your customers started so that they can concentrate on what ever it is that they actually want to accomplish?
nVidia, PLEASE at least offer basic stuff that you’ve already done so that everyone doesn’t have to start from scratch and hours of research.
