AI Technical Summary

Technical Problem

In the prior art, memory fuse solutions have problems of waste of human resources and the use of equipment being vulnerable to recall.

Method used

By responding to the startup signal of the boot kernel to start the application process during the device startup process, the device is controlled to switch to the trusted operating system, and obtain the life cycle state of the one-time programmable memory in the trusted operating system, and determine its fuse state. If an exception is caused, a prompt message will be sent and fuse operation can be performed automatically.

Benefits of technology

It realizes that equipment that automatically screens and repairs fuse abnormalities without recalling all equipment in the same batch, saves human resources and does not affect the normal fuse operation.

Abstract

The invention provides a memory fuse detection method and device, electronic equipment and a vehicle. After a starting signal for guiding a kernel to start an application process in the equipment starting process is responded, the equipment is controlled to be switched to a trusted operating system; whether the fuse wire of the one-time programmable memory is abnormal or not can be judged by acquiring the life cycle state of the one-time programmable memory in the trusted operating system, and prompt information is sent out when the fuse wire of the one-time programmable memory is abnormal. According to the scheme, the fuse state of the one-time programmable memory can be detected in the startup process, and a prompt can be given out once the fuse is found to be abnormal. Therefore, the equipment with the abnormal fuses can be automatically screened on the premise that all the equipment in the same batch is not recalled, manpower resources are saved, and work of the equipment with the normal fuses is not affected.
