We are seeing some differences in the communication error rates between the ttyTHS1 serial port nano, and the ttyTHS2 on the eMMC nano. Are there any signification differences between the 2 ports that we should be aware of? Specifically, when we communicate with ttyTHS1 on either an SD or eMMC nano, we can run at 921600 baud, sending 2048 byte messages - no problem!
When we send from one nano (ttyTHS1) to an eMMC nano ttyTHS2, we’re seeing errors if we go above 57600 baud, 200 byte messages.
I’m trying to do due diligence here - there are other potential culprits for this problem (e.g. a non-NVidia carrier card), but I want to make sure that the eMMC2 ttyTHS2 is not a path that needs further research on our part
