Interrupt Issues Based on NXP Core imx6ulx

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

Measuring the Precision of High-Precision Timers in Linux Driver Development

Measuring the Precision of High-Precision Timers in Linux Driver Development

Introduction Today, we will evaluate the high-precision timers in the Linux kernel, while also conducting cross-testing using a Tektronix oscilloscope and a DS100 Mini digital oscilloscope. Due to project requirements for precise timing cycles, we need to assess its feasibility and verify whether the oscilloscope from Atomic Clock can support the embedded development process.
