To address the issue of multiple concurrent system upgrades that heterogeneous systems face,which often take a long time and increase the waiting burden on users.Optimization using OTA upgrade technology.Through a deep innovation of the upgrade process,a parallel flashing method based on A core and M core was proposed,and the Norflash flashing of M core adopted a concurrent flow control method.Experimental results have shown that it can effectively shorten the upgrade time of heterogeneous systems,ensure efficient and safe completion of upgrade tasks under various power conditions,and bring substantial enhancement to the OTA upgrade experience of intelligent vehicles.
