description The invention discloses an ECU program online flashing method, an ECU program online flashing device, a program flashing system, electronic equipment and a storage medium. The method comprises the steps that an ECU program online flashing program is started, and the ECU program is flashed online; wherein the data in the ECU watchdog register are modified according to the start of the online flashing process of the ECU program, and the data in the ECU watchdog register are reset according to the end of the online flashing process of the ECU program. According to the scheme, the resetting and restarting parameters of the watchdog are modified, so that the ECU program can be flashed and written with sufficient time, and the situation that the process of the ECU program flashed and written is damaged by the watchdog due to timeout of ECU program flashed and written is prevented. According to the method, data in an ECU watchdog register are modified when the ECU program online flashing process starts, ECU program
