and receiving an interrupt instruction of the Bootloader so as not to test the test sample piece through the interrupt instruction.
Specifically, the interrupt instruction in this embodiment is sent by the computer control program, and when the test of the Bootloader fails, the Bootloader is stopped from testing the test sample, where the test of the test sample includes updating software of an application APP of the test sample.
It should be noted that, if the matching of the test data and the fault data fails, the Bootloader is tested successfully, and the Bootloader is allowed to test the test sample.
Therefore, in the embodiment, the test sample is not tested through the interrupt instruction by receiving the interrupt instruction of the Bootloader, so that the test sample is prevented from being invalid due to software bugs updating the test sample after the Bootloader fails in testing.
Based on the foregoing embodiment, in this embodiment, after matching the test data with the fault data, the method further includes:
