看到DSP2812手册上的PWL 部分有这么一句话Do not use all zeros as a password or reset the device after performing a clear routine on the flash. If a device is reset when the PWL is all zeros, the device cannot be debugged or reprogrammed. To summarize, a device with an erased flash array is unsecure. A device with a cleared flash array is secure.这里erased flash是不是是只写0xFF，cleared flash 是指写0x00 我的理解对吗 问题可能有点弱 但小弟还是想确认下 先谢了 |
