4results about How to "Simplify the troubleshooting process" patented technology

This utility model belongs to the field of power distribution cabinet technology, and in particular to a detachable power distribution cabinet. It includes a power distribution cabinet structure, with a front-end detachable structure on the front side and a side-end hinge structure on the side end. The power distribution cabinet structure is movably connected to the front-end detachable structure and the side-end hinge structure via a splicing structure. By setting the front-end detachable structure and the side-end hinge structure, the front and side ends of the power distribution cabinet structure can be unfolded. Combined with the splicing structure, the overlap between the front-end detachable structure, the side-end hinge structure, and the power distribution cabinet structure is reinforced. This provides comprehensive, enclosed protection while allowing for flexible and controllable unfolding, avoiding obstruction of vision by arms or maintenance equipment, facilitating maintenance work, reducing the complexity and time required for troubleshooting, and simplifying the daily maintenance and troubleshooting process.

This invention discloses a method for full lifecycle debugging of RTOS in AMP systems based on Linux terminal penetration. The core steps of this method include: during system initialization, loading an enhanced inter-core communication driver, configuring multiple functional channels and shared memory, completing interactive terminal application initialization, and adapting to multi-mode interaction; during command pass-through and forwarding, capturing user input and processing it differently, encapsulating it according to a preset protocol, and achieving differentiated transmission through an adaptive window flow control algorithm; during real-time response echoing, ensuring interaction consistency based on bidirectional state synchronization and precise terminal simulation; and during the full lifecycle startup log capture stage, achieving full startup log capture, Linux-side time alignment, and late-start recovery. This invention requires no additional hardware, reduces debugging costs and system resource consumption, improves multi-core collaborative debugging efficiency, achieves full lifecycle debugging coverage of the RTOS, and is adaptable to resource-constrained small-core scenarios.

The invention provides a method for verifying cache validity and a computing device, the method is applied to verification of cache validity of a master device during data transmission between the master device and a slave device of a high-speed serial bus, and the method comprises the following steps: the master device opens a first cache to map a first continuous memory allocation area; the slave device maps a second cache of a second continuous memory allocation area; the master device writes first data into the mapped first continuous memory allocation area; the master device writes first data into a second continuous memory allocation area of the slave device in a first mode; the master device informs the slave device of the data write-in message and the first data in a second mode; data received from the device is used as second data; the slave device reads data in the second continuous memory allocation area as third data; and comparing the second data with the third data, and if different, verifying that the cache of the master device is valid. According to the technical scheme, the cache validity can be verified, the hardware use cost is reduced, and the data transmission efficiency is improved.
