Interrupt Issues Based on NXP Core imx6ulx

by
Interrupt Issues Based on NXP Core imx6ulx

Requirement Description For scenarios that require extremely high real-time response (such as power failure detection), interrupts must be used. However, for the imx6ulx, which is a Linux platform, there are no convenient interrupt operations like those in RTOS. To achieve the same smooth operation, both the kernel driver and the application layer program need to … Read more
