How can I update firmware for CPU 315-2DP

vhgod Posts: 1 Rating: (0)	Hi everybody. Now I have a CPU 315-2DP. But it works unstably. A error occurs, all leds lit. With this error, Siemens recommends update firmware (I referenced this link: /tf/WW/en/Posts/12419 ). But I can't. The firmware version is V2.0, the capacity of MMC is 64Kb. But to update the requirements is: the least capacity of MMC is 4Mb or the module in the station whose firmware is to be updated must have firmware version V2.6.1 or higher and be accessible online and the module status of the CPU can be checked with STEP7 in the online mode. Version A0.21.0 or higher must be displayed to be able to perform the firmware update. So how can I update firmware for my CPU. Thanks and best regards
