'Q1. 'At the very least, how does NXP account for the abrupt abandonment of its chapter on SmartDMA in the reference manual?'
-->This question is out of my scope, and I cannot give a definitive answer. I need to try to find the relevant team and product owner, but I'm not sure if I can, as re-org or unanswerable issues are common.
Q2. The API documentation is incomplete, and the chapter on SmartDMA stops mid -sentence after less than one page. Meanwhile the documentation for the FlexIO says we must use SmartDMA. Nowhere is there any instruction for how to do this unless I want to reproduce the camera examples. We have no list of DMA triggers or request sources. This situation is totally unusable. Here I am midway through a project, the hardware is there and there is no support from the manufacturer ANYWHERE of how to use DMA for a non-standard FlexIO application. This is just too unreasonable.
--> How did you arrive at this conclusion?
