I am looking at using the TX2 developer kit for a project that we are spinning up. One of our requirements is having 2 SPI slave interfaces (meaning the TX2 is the slave). I see from the documentation that SPI1 is available on J21, and that SPI0 and SPI2 are available on J23. SPI2 is labeled as the ‘touchscreen SPI’. My questions for any of you who have experience with this board are:
- Can both SPI0 and SPI2 be used as generic SPI interfaces? Is there something special or some limitation to SPI2?
- I saw in a thread on this forum that someone had trouble with and SPI interface in slave mode, but there was no elaboration. Has anyone gotten SPI slave to work reliably? If not, what are the issues that you have come across?
Thanks in advance.
